HighGear Tips
Antenna Assembly
Screw the mast into the base. Loosen the set screw from the top of the
antenna mast. Insert the whip into the mast until it touches the bottom.
Lightly tighten the set screw.
Antenna Mounting
The metal body of your vehicle serves as the ground plane for the antenna.
The ideal location for the antenna is on the center of the roof or trunk lid, as
far away from any structures like luggage racks as possible. Make sure that
all hardware and connections are tightened securely.
Checking The SWR (Standing Wave Ratio)
Make sure your vehicle is in an open area at least 30 feet from any metal
objects and with the doors, hood and trunk closed. Connect an SWR
meter in the coax line between the radio and the antenna (unless your
radio has a built-in SWR meter). Check the SWR on both channel 1 and
channel 40. Readings under 2:1 are considered acceptable, with 1.5:1 or
lower being desirable.
Note An SWR reading of over 3:1 on both channel 1 and 40 generally
indicates an open or shorted coax or a poor ground connection.
Re-check these conditions before proceeding. Do not use the radio until
the problem has been corrected. An SWR reading between 2.0 and 3.0
generally indicates a problem with coax quality or length, or an
inadequate ground plane.
Tuning the Antenna:
If the SWR on channel 40 is higherthan channel 1: Remove the whip from
the mast and trim it by 1/8
11
to 1/4
11
using a bolt cutter or hacksaw.
Re-insert into the mast, tighten the set screw and again read the SWR. If
the SWR reading is still higher than channel 1, repeat until the two readings
are approximately equal. If the SWR on channel 1 is higher than channel
40: Loosen the set screw, pull the whip up 1/4
11
, tighten the set screw and
read the SWR again. Ifthe SWR is still higher than channel 40, repeat until
the two readings are approximately equal. Then firmly tighten the set screw.
