Sinclair SD241-SF P Series Installation Instruction

ANTENNA INSTALLATION GUIDELINES
1. Upon receipt of your antenna, please check the material against the parts list enclosed. If shortage or
damage is apparent, notify the carrier immediately.
2. Inspect the antenna feed connector(s) to determine that it mates with the end of your transmission line. Do
not remove any connector or cable from the antenna as they are all part of your antenna.
3. Verify that the frequency to which the antenna has been tuned is the frequency on which your radio system is
to operate. This information is on the label which also shows the model and serial number of your antenna.
4. Assemble antenna including mounting clamps as shown on your assembly sheet. Tightening torques
provided must be adhered to when assembling and installing your antenna. Drain holes in the mast base and/or
radiating element must face downwards and remain unobstructed at all times.
5. Always protect the cable harness and radiating element from damage when moving, lifting or resting your
antenna.
6. A check of the antenna VSWR is recommended prior to installation and measurements should be recorded
for future reference.
7. After checking the VSWR of the antenna, mount the antenna to the tower and ensure that it is solidly
grounded. Do not rely on the feed cable for ground return. Connect the station transmission line to the antenna
making sure that the centre pin of both connectors are centred. Tighten both connectors firmly by hand. Do not
use pliers. Carefully weatherproof the cable connection (Refer to Weatherproofing Instructions 005032, supplied
with Weatherproofing Kit). Failure to weatherproof the cable connection will result in improper operation of your
antenna. Properly secure the feed cable and antenna transmission line to the tower in the best position to avoid
damage.
8. A careful visual check is recommended to insure that:
a) All mechanical connections are securely made.
b) The antenna is mounted on the proper ledge of the tower with sufficient physical clearance.
c) All connections have been carefully wrapped with weatherproofing material to prevent moisture
problems.
