ABSTRACT

The results of attenuation, VSWR, watertightness, stability,pliability and other tests on 33 various sample constructionsshow RG-214/U, RG-217/U and RG-218/U can be redesigned to be water-tight at 1000 psi and have less attenuation, better attenuationstability, be more pliable, and have better abrasion resistancethan the standard designed cable. The new designs would still becompatible with the connectors presently used on the standardcables. The size of the cable can also be decreased, if desired,but then the connector would require redesign. The resultspresented show the technique used to manufacture the braid watertightis good for pressures greater than 2500 psi. The attenuation on allRG coaxial cable can be decreased by an improved braid'design. RG-214/U,which is considered one of the better designed RG cable, has better than20% less attenuation from 10 MC to 10 GC with the improved braid design.The pliability of a cable depends almost completely upon its jacketstiffness. Pliability results are presented that show polyurethanejacketed cables are vastly more pliable at 8OOF, OF and -40OF thanpolyvinylchloride or polyethylene jacketed cables. The programfor the next interval is presented.

1.3.2 Samle discussion - Samples 16 and 19 were canceled because themodified high molecular weight polyethylene is no longer available.Through an identification error the first interim progress reportincorrectly reported sample 9 was manufactured and ready for test. Thesample has now been manufactured and will be tested with other phase IIcables. The first run of sample 14 was rejected because its dielectricwas extruded to the same dimension as sample 13. The impedance resultingfrom this error negated the intent of the sample, The sample is beingrerun and will be available for test during the next reporting period.Sample 31, 32 and 33 were manufactured to examine the effect of the braidangle on the attenuation braid factor. The attenuation of these threesamples were measured but no other tests will be performed. The cableswith polyethylene jackets were not subjected to the abrasion resistancetest since the polyethylene waxes the abrasive rod and makes the testmeaningless.

1.3.3 Attenuation test results - The results of attenuation measurementson the samples are presented in table 1.2 on page 9 and in graphs 1.1 to1.29. The graphs compare the measured results at 10, 50, 100, 250 and 500megacycles and 1.7, 3.0, 5.0, 8.0 and 10.0 gigacycles to a curve drawnfrom calculated results at 10, 100, 1000 and 10,000 megacycles. Thecalculated results were obtained with the following expressions:

1.3.14 Discussion of attenuation test results - Graphs 1.1 through 1.29 show themeasured attenuation of the samples is quite accurately predicted by the expressionsgiven In paragraph 1.3.3 on page 8. Graphs 1.27, 1.28 and 1.29 indicate the braidfactor does not completely describe the attenuation characteristics of the braid. Allthe graphs show a need for evaluation of the contribution of the braid to the attenua-tion at frequencies above 3 GC. The results show a silver plated braid yields a muchlower high frequency attenuation than a bare copper braid. The following paragraphsdiscuss individual attenuation test results in more detail.

1.3.4.1 Discussion of attenuation test results on samples 1, 21 and 30 - Graph 1.30,page 1.0, presents a coQmprison of the measured attenuation of samples 1, 21 and 30.Sample 1, the regular RG-214/U construction, has the highest attenuation of the threeaud increases above its calculated attenuation at frequencies above 3 OC. Sample 21,manufactured with a smaller size silver plated braid strand than sample 1, offersapproximately 4% attenuation improvement from 10 MC to 3 GC . Above 3 GC the improve-ment increases to 440 at 10 GC. This particular sample of RG-214./U (sample 1), how-ever, measured slightly higher than the averase RG-241/3 attenuation from 3 to 10 CC,so sample 21 probably does not offer quite 0 improvement to the cable design at10 GO. The measured attenuation of sample 21 closely follows its computed values.Sample 30, which is RG-_21/u core with a double silver plated ribbon braid, offersover 20% less attenuation than RG-21'I. across the entire test frequency band of 10 MCto 10 GC. The measured attenuation of sample 30 agrees with its calculated attenuationat low frequencies but Is less than calculated at higher frequencies. A comparisonof the measured and calculated attenuation curves (graphs 1.26, page 35) Indicates thedissipation factor used in the calculations is higher than actual. Note the measuredattenuation above 500 MC of sample 30 and the measured value of the RG-217/U is higherthan calculated. This shows the ribbon braid over a .285 inch dielectric yields anattenuation as good as or better than a standard braided .370 inch dielectric, asavings of 23% in core diameter. The ribbon braid also decreases the braid thickness.

1.3.4.2 Discussion of attenuation test results on samples 3 and 22 - Graph 1.31, page41, shows the measured attenuation of sample 3, which is regular EG-2/1 , and sample22, which has a silver plated braid over RG-218ft core. The two samples have approx-imately the seme attenuation from 10 MC to 3 GC. At 3 GC the attenuation of sample 3begins to increase rapidly until, at 10 MC, it is three times the attenuation of sample22, which has followed the curve of its calculated values. This shows the high fre-quency attenuation of the large (.680 inch dielectric) can be improved, even though Itis large enough to transmit higher modes at frequencies above 5.7 GC. (The TEio above5.7 GC and the TE01 above 8.04 GC) Over half the attenuation of sample 22 at 10 GCis caused by dielectric losses.

1.3.4.3 Discussion of attenuation test results on sample 7 and 8 - Graph 1.32, page43,, presents the measured attenuation of samples 7 and 6 compared to the measuredattenuation of sample 2, which is regular RG-217/U. Sample 7 shows the improved high

'frequency attenuation characteristic of a silver plated small size braid wire over thelarger size bare copper wire. The increased low frequency attenuation of the smallsize wire is also shown. Sample 8 shows how the high frequency attenuation is in-creased when the silver plate is omitted.

1.3.4.4 Discussion of attenuation test results on samples 1U and 12 - Graph 1.33,page 41•, shows the increased attenuation or the braided center conductor constructionof samples U1 and 12 over the solid center conductor construction of sample 7.

1.3.4.5 Discussion of attenuation test results on samples 10 and 13 - Graph 1.34,page 45, shows the increased attenuation of sample 10, caused by the 19 strand, strandedcenter conductor. It also shows the attenuation of sample 13, which has the samecenter conductor as RG-217A3 but a cellular polyethylene dielectric with a smallerdiameter than RG-217/U. Sample 13 shows how a cellular polyethylene dielectric candecrease the size of the cable and yield the same attenuation. The size may be keptconstant and the attenuation decreased by the same techniques.

1.3.4.6 Discussion of attenuation test results on sample 17 - Graph 1.35, page 46,shows the improved attenuation of the flat copper braid of sample 17 compared to theattenuation of sample 7.

1.3.4.7 Discussion of attenuation test results on samples 31, 32 and 33 - Graph 1.36,Page 47, shows the braid factor does not completely describe the attenuation character-istics of samples 31, 32 and 33. Samples 31 and 32 have the same braid factor assample 7 while sample 33 has a smaller braid factor. Apparently, other variables,such as braid angle, must be considered to accurately predict the attenuation char-acteristics of a braid. The results, however, also show the braid factor predictsthe braid's contribution to the attenuation to accuracies compatible to manufacturingtolerances.

1.3.4.8 Discussion of attenuation test results on other samples - The attenuation ofsample 15 (graph 1.13, page 22) Is much too high for consideration in this application.The increased attenuation is caused by the high dissipation of the elastomeric poly-ethylene and eliminates the material for use as a coaxial dielectric, but it could beemployed in the manufasture of an isolation cable. Sample 18, 20 and 23 through 29vere manufactured for evaluation of jacketing material and their attenuation donot contribute to the discussion. Their attenuation had to be measured, however,to examine the contamination effect of the Jacketing material.

1.3.5 VSWR test results - Table 1.3, page 49, lists the measuredvoltage standing wave ratio (VSWR) of the samples at 1.7, 3.0, 5.0,8.0 and 10.0 GC.

1.3.6 Discussion of VSWR test results - The VSWR of the samples,measured at the same frequency and time the high frequency attenuationmeasurements were made, indicate the cable mismatch at these frequencies.These mismatches indicate the nominal impedance of the cable, theuniformity of the cable, and the amount of the measured insertion lossthat is not caused by the attenuation of the cable.

1.3.7 Stability test results - The stability test results are presentedin table 1.4, pages 50 and 3, and in graphs 1.37 through 1.54, pages52-69. The stability is measured by comparing the measured highfrequency attenuation of the cable after manufacture, after heat aginafter flexing and after cold bending. The contamination test of MIL-C-17Cconsists of the first two steps. The graphs are arranged, with twocable stability test results on each graph, in a manner to aid thediscussion of the results.

1.3.8 Discussion of stability test results - Graph 1.40 shows thestability of sample 2, which is RG-217/U and sample 7, which is RG-217/Ucore with a silver plated 36 gauge strand braid. The much improvedstability of sample 7 indicates a silver plated braid is a more stableconstruction. Graph 1.41 shows the stability of samples 7 and 8 whichare identical constructions except sample 7 has a silver plated 6raidand sample 8 has a bare copper braid. Graph 1.49 shows this is also trueon other size cables since sample 3 is regular RG-218/U and sample 22 isa silver plated braid version of RG-218/U. Graphs 1 51 1.52 and 1.53show the difference between a contaminative type instability and insta-bility that is caused by the braid construction. Samples 24, 26 and 28have polyvinyl jackets while samples 25, 27 and 29 have noncontaminatingpolyvinyl jackets. Heat aging of samples 24, 26 and 28 caused a largeattenuation increase regardless of the braid construction; silver, bareor tinned copper. Heat aging caused little attenuation increase onsamples 25 and 29, which have silver and tinned copper braid respectively,bud did cause some on the bare copper construction of sample 27. Sample27 failed the contamination test of Mil-C-17 because its attenuation at3 GC after heat aging (14 db) is more than 15% of its original attenuation(12 db) even though 14 db is maximum at 3 GC. This is common with barecopper braided polyethylene cores. The two increases apparently havedifferent causes. In one case the polyvinyl jacket affects the attenuationby contaminating the polyethylene dielectric and increasing its dissipationfactor, while the noncontaminating jacket does not affect the dielectricbut the heat affects the bare copper braid, perhaps by corrosion.

1.3.9 Watertightness test results - Table 1.5, this page, lists the watertight-ness test results after eanufacture and after conditioning on samples U,, 5 and 6.

1.3.10 Discussion of watertightness test results - The watertightness resultsshow the techniques for making a cable with a solid center conductor and a dia-meter of less than 500 mile over the braid is acceptable for 1000 psi applicationsbut the technique to watertight stranded center conductors and the techniquesused on larger cables must be improved. A stranded center conductor increasesa cable's attenuation and really does not make the cable more flexible because ofthe stiffness of the Jacket. Improving the vatertighting techniques on this typeconstruction, hovever, should be investigated because the techniques used onsolid center conductor cables make the cables watertight at pressures greaterthan 2500 psi but the smooth solid center conductor extrudes out of the core onshort lengths. The stranded center conductor might improve this bond strength.Attempts to watertight without the tape over the braid should be investigatedsince cable could be manufactured with a smoother Jacket if the polyethylene tapeculd be eliminated.

1.3.11 Flamiability test results - Table 1.6, pages 71 and 72, lists the flam-mability test results.

1.3.12 Discussion of flammability test results - The results show that all theJacketing materials burn or melt but the polyInyls are self extinguishing whilepolyethylene and polyurthane jackets are not self extinguishing. The resultsalso indicate the noncontaminating polyvinylchloride is a little harder to ignitethan the standard type polyvinylehloride (about same to ignite as polyethylene)but the standard type extinguishes itself sooner.

1.3.13 Other test reaits - The results of the dimensional measuriemets, capsaitanoesIpedance, cold b~end abrasion and corona test results are lasted in Table 1.7,page 73 MAd 711.

1.3.14 Discussion of other test results - The abrasion results mit be ompensatedfor Jacket wail thickeess and braid construction but the results show an outstandingabrasion resistance for polyurtbane. The abrasion resiatance test Mn polyethylenvas meaningless as the wax like material filled the abrasive rods and then wouldnot wear because of its low coelcient of friction. Several samples failed the coldbend test but a pattern of failure was not established.

1.3.16 Discussio lity test lt - The pliability testresults show the p lab lity or a ca) e, at thd present state of the art,depends mostly upon the jacketing material. The results on sample 18compared to results on other samples, show polyurethane is more pliablethan any of the other material tested. The effect of solid vs strandedconductor stranded braid vs. ribbon braid i hidden by the stiffnessof the polyethylene Jacket. The effect might be noticeable on sampleswith polyurethane Jacket. The results also show the polyurethauejacketed sample was not much stiffer at -40OF than it was at 807F.

1.4 CONCLUSIONS

1-.41 General conclusions - While the results are not completelevaluated it can be concluded that with slight design changes allthree cable types can be manufactured watertight at 1000 psi andhave decreased attenuation, decreased size, more abrasion resistanceand greater flexibility.

1.4.2 Conclusion from attenuation test results - The attenuation ofRG-21H4/U, RG-217/U, and RG-218/U can be slightly decreased across thefrequency range of 10 MC to 10 GC by designing to a minimum braid factorand can be decreased considerably by using a flat ribbon braid. ;Thehigh frequency attenuation can be greatly improved by using silverplated braid strands.

1.4 .3 Conclusion from watertightness test results - All the cables can bemanufactured watertight at 1000 psi if RG-214/U is redesigned with asolid center conductor. Since a solid center conductor tends to extrudeout of the dielectric core at higher pressures it is necessary tocontinue to improve the watertighting techniques on stranded centerconductors in the hope the stranded conductor will have better bondstrength to the core and produce watertight cables at even higherpressures.1.4.4 Conclusion from abrasion resistance test results - A Dolyurethane

Jacket has vastly better abrasion resistance than any of the otherJacketing materials investigated. The size of the cable can beecreased by using a thinner wall of polyurethane and still have greater

abrasion resistance than cables manufactured with the usual wall thicknessof polyethylene and polyvinylchloride.

1.4.5 Conclusion from pliability test results - While polyethylenejacketed cables are more pliable at room temperatures and cold tempera-tures than polyvinylchloride jacketed cables, a polyurethane jacketyields a cable that is much more pliable at all temperatures.

2.1.1 Phase I

2.1.1.1 Evaluate test results on study samples - The test resultspresented in this report will be completely evaluated during the firstportion of the next reporting period.

1. 2.1.2 Phase II

2.1.2.1 Desiln of preliminary cables - All preliminary cables will beIj designed and manufacturing will be started.

2.1.2.2 Improve watertightness - Techniques will be perfected formaking stranded center conductors watertight. Techniques will also beperfected to make RG-214/U and RG-218/U watertight at 1000 psi. Thetechniques will be similar to those used to make RG-217/U watertight at1000 psi. Advance cable designs similar to RG-214/U, RG-217/U and RO-218/Uwill lb manufactured in an attempt to make cable watertight at 2500 psi.
