2 The jumper cable is a flexible low loss cable (1/2"), which is usedat the ends of the feeder. It protects the connectors from theforces caused by the feeder cable. Antenna side jumper cable(2A) is 1.5m and at the BTS side(2B) is 3m.

3 7/16 connector are made of silver plated brass or a special gradeof copper. All connectors are IP68-classified.

4 The grounding kit ensures that the Antenna line is DC groundedas a protection against lightning.Two grounding kits shall beinstalled in one (1) feeder run,one at the antenna side andanother one before the bend.All grounding kits shall beterminated to alloted busbar with dedicated 35mm2 groundingcable directly terminated to earth

5 The RF-feeder is corrugated coaxial cable. It can be of differentsizesi.e. 1/2, 7/8 and 1 5/8, depending on the length of the

mast and the desired attenuation.6 Supplied Cable clamps are made of stainless steel and plastic

and are easy and quick to install. Design of the clamps preventsover tightening of feeder cable.Minimum spacing of the clampsfor 7/8 feeder cable is 900mm and max of 1000mm.

7 A compact EMP protector protects the BTS against lightning andover voltage that may occur down the antenna line.

2. Hoist the antenna up to the antenna support.

Note: when hoisting antenna in foul weather conditions, it is necessary to control antennamovement to avoid damage. Use ropes etc.

3. Install the antennas on the antenna support exactly vertical or with a specified offset.

4. Use the data specified in the site installation documentation to set the antenna heading,height, vertical and horizontal separation.

5. Connect one end of the antenna jumpers to the antennas, leaving the opposite endsopen.

Note: the open ends should be protected from moisture.

Contact between metals from the opposite group can

generate severe corrosion of the conductor from theanodic section. Care must be exercised whenterminating one conductor to another. Where possiblecommercially available transition sections/joints shouldbe used.

Attention must be given to the following:

Use only copper to copper connections where possible. Ensure that bare copper is not allowed to be placed in

contact with zinc or steel of a tower. In such cases tinplated copper may be used. Alternatively, stainless steelsection may be placed between the copper and zinc oriron surfaces.

Ensure correct fixing of screws, nuts and washers.Copper or stainless steel screws and washers must beused against bare copper surfaces.

If possible, use anti-corrosive compound on the surfacesbetween dissimilar metals. This prevents oxidation overlong periods.

ANTENNA LINELoose RF-connector laboratory test

How loose RF-connector influences to performance:

It seems that also 7/16 connector is very sensitive to fixing torque. Whenyou loosen the connector, at first you'll get intermodulation problems, thenyou loose return loss values. Very easily you'll get 6...12dB return lossvalues, when you loosen slightly the connector (fixing torque 5...10Nm).However most of the power is still passing the loose connector, but you get

VSWR alarms and insertion loss increases easily 1..2dB. Further, think about if you have 1,5m jumper cable with both ends loose

connector. The signal reflects on the both end of jumper and the result is3rd stage reflections. Depending the frequency and cable length(=depending of the phase of reflection), you'll get very very easily VSWR

problems.
