Antenna System analysis

At Clay's we do more than slap a meter in line, check the SWR and call it good. We perform a thorough Antenna System evaluation. Eight Antenna System checks are performed. If the Antenna is removed, a lock washer is installed and locktite is used on the threads. If the Antenna stud is removed, a star washer is installed.

Antenna System analysis includes: Checking the antenna for breaks, checking the antenna for proper calibration, checking the antenna height - (Diesel Trucks), check for adequate ground, checking the antenna for proper mounting location, checking the stud mount for corrosion and proper duty, check the coax for breaks, check the coax for proper impedance.

Setting the antenna SWR with an amplifier can get involved. The antenna SWR is calibrated at the back of the amplifier with the amplifier in line and turned off. Once the antenna is properly tuned the meter is removed and re-installed at the radio with the amplifier in line. The antenna SWR level is then measured with the amp off and then with the amplifier switched on. The SWR level must be correct on all power levels of the amplifier at the radio with the amplifier switched to the on position. Most shops don't check the SWR match at the radio with the amplifier turned on. This is a critical mistake. We measure the SWR level with a Bird 43 watt meter. The forward and reflected carrier level is then entered into a hand held computer for a very accurate SWR measurement.
