MEASURING SWR

Measuring SWR shows you how much of your radio's transmit
power is reflected from the antenna back into the antenna ca-
ble, generating heat and wasting power. With this information,
you can adjust the length of your antenna or antenna cable so
your antenna and radio combination can produce the maxi-
mum power they are capable of producing.
For more information about measuring SWR, see the ARRL
Handbook , available at your local library.

CONNECTING THE METER

To connect this meter to your CB or amateur radio and your
antenna, you need RG-58U coaxial cable (not supplied) with
a PL-259 connector on both ends (such as RadioShack Cat.
No. 278-968). The cable must reach from the back of the
meter to your radio's antenna jack.
Follow these steps to connect the meter to your radio and an-
tenna.
