OVERVIEWBlackheart nternationals imited Visibility Concealable

Antenna VCA is a roundbreakin tactical antenna that issmaller, lihter and less obtrusive than conventional externalcombat radio antennas, yet delivers maximum field performancefor battlefield communications

he imited Visibility Concealable Antenna VCA is basedon the proven patchpanel antenna confiuration, but exceedstraditional patchpanel antenna performance in several areasirst, the VCA is a broadband antenna effective for operationswithin the z frequency rane Second, in spite of itsbroadband operation, the VCA requires no tunin or operatorintervention hird, the VCA transmits via circular polarizationto eliminate dead zones or the need for any directional alinment Because of its omnidirectional transmission and compact

desin, the VCA can be worn discreetly and efficiently anywhere on the operators bodytucked in a pocket, or attachedvia hookandloop patches to the radio or radio pouch o morewhip antennas pokin the operator in the back, catchin on doorframes or snain on obstacles when enterin or exitin a vehicle

he Blackheart nternational VCA is available with , and inch lenth RAU cables, and blackstandard or optional, extracost camo patterns ultiCam, Universal Camo, Desert ier Stripe and WoodlandCamo he cable delivers Watts peak, Watts continuous with no amp C connectors fit hales, arrisand SCARS units SA connectors fit otorola units

BACKGROUND & CURRENT STATUShe Blackheart nternational imited Visibility Concealable Antenna was developed specifically for militaryspecial operations applications he objective of the VCA project was to produce an antenna which would914-#%4155#$41#&4#0)'1((4'37'0%+'5(14/#:+/7/(4'37'0%;%1/2#6+$+.+6;4'&7%'9'+)*6(146*'12'4#6142418+&'#564'#/.+0'&241(+.'6*#6917.&$'.'551$6475+8'#0&4'&7%'+06'4('4'0%'9+6*6*'12'4#6145

PERFORMANCEraditional antenna desins use either monopole or dipole antenna elements that are tuned to a specific frequency rane The LVCA, on the other hand, is comprised of an array of monopole antenna elements coupledin a dual-offset array that allows the antenna to receive and transmit on multiple frequency ranges. hecumulative effect of the individual antenna elements coupled toether enable transceiver operations on multiplefrequency ranes that monopole or dipole antennas cannot operate on because they are tuned to a sinle frequency rane urthermore, traditional antennas are typically metal tubin or wire, whereas the VCA is embedded in a Printed Circuit Board in a pattern that is impossible to create in freestandin metal or wire

he VCA performs exceptionally well in the field, and exhibits above average field results when compared tostandard whip antennas which are supplied with the subject transceivers or example, in one overseas theateroperation, the VCA delivered flawless ten-mile line-of-sight communication on a arris radio between theoperator and an aircraft

n sum, while the broad frequency VCA wont o headtohead with a tuned and frequency specificwhip antenna, it covers 90% of the operational requirements of urban and open battlefield troops and operatorsallwith reduced weiht and a more discreet, tacticalfriendly profile

Due to the new technoloy and application desin of the VCA,

this antenna exhibits neative ain in a laboratory environment

a partial result of incompatability between this new technolo

y and conventional testin processesequipment ield testin, however, has proven the VCA to exhibit aboveaverae

field results when compared to standard whip antennas, and

covers of operational requirements of urban and open

battlefield troops and operators his antenna is currently be

in used intheater by special operations teams

*TEST NOTES:

he complete structure is radiatin, and therefore is considered part of the antenna durin the ain calibration erriteloaded cables were used to mitiate R

radiation from test cables

he calibration was completed usin a ain Standard ransfer easurement S A standard ain loperiodic antenna was used for the radiator and

another standard ain loperiodic antenna was used as the ain standard he antennas were alined to the peak of the beam and the Received Sinal evel

RS data was recorded usin ARA proprietary software he differential RS is used to calculate the ain of the Antenna Under est AU
