12 Mobile Antenna Installation
Tuning the Antenna
NOTE: Tune antenna in an open area at least 12 feet away from any metal objects.
NOTE: Lengths shown on the cutting chart are approximate. Due to antenna variations and mounting
location effects, we recommend cutting the antenna rod 1 1/2” longer than the chart and then
cutting 1/2” off at a time until reflected power is minimized.
NOTE: DUE TO ANTENNA INTERACTION WITH VEHICLE, SOME LOW BAND ANTENNA
MOUNTING LOCATIONS WILL NEVER ACHIEVE 1.5:1 VSWR. In this case, trim the whip
for minimum reflected power. A simple table for converting the radio of forward power and
reflected power to VSWR is shown below in Tabl e 3 .
1. Locate the transmitter frequency on the cutting chart. In the case of multiple transmitter
frequencies, calculate the mid-frequency and locate on cutting chart. Read desired whip
length from the chart. Cut the whip 1 1/2” longer than this length.
NOTE: Trim the antenna rod (Low and High band) from the bottom only. On the UHF antenna whip,
trim the whip from the bottom of the rod below the phasing coil.
2. Use the set screw to secure the antenna whip in the whip adaptor assembly.
3. Using the in-line wattmeter, measure forward and reflected power at the desired transmit
frequency and calculate VSWR using Table 3.
4. If VSWR is >1.5:1, then trim off 1/2” and repeat Step 3.
5. Repeat steps 3 and 4 until minimum VSWR is obtained.
