IMPROVING SWR
There are several ways to improve the SWR of your radio/an-
tenna combination. Try these first.
Be sure you are using the type of cable recommended for
your equipment. If the manufacturer recommends a 50-
ohm cable, do not substitute another type that has a dif-
ferent impedance.
Confirm that you mounted your antenna according to the
manufacturer’s instructions. The angle and the base
arrangement can affect the SWR reading.
Adjust the length of your antenna according to the
instructions provided by the manufacturer. A change of
as little as
1
/
8
inch can make a measurable difference.
See your radio’s and antenna’s owner’s manuals.
