Have you tuned the length of the 30m antenna? Out of the box it might
be wrong.
You also need a ground strap, if you don't want a permanent
installation. I hopr your car is metal, not fiberglass. You may need
some straps to hook other parts of the car together, such as roof to
body, or hood to body, to get more metal in the ground plane. If you
plan to operate while the car is running and use car 12v, you wuill have
much more to do, but if you operate when the car is off, this is
enough.
I operate 40, 30, 20, 17, and 15 with similar antennas (Hamstick or Pro
Am) and a tri-mag mount and a short piece of #14 zip cord (both) to a
screw on the car. For feeding the antenna, I use coax to a balun and
then twinlead through the sunroof. I use the WB6ZQZ step-down balun and
usually use it on the 25 ohm setting, depending on what makes the tuner
happiest.

Hi all,
I have a new set of mobile antennas, pro am series with magnet mount.
Most
works just fine but I have one thing I don't understand. I have a K1
and a
K2 and while the K2 (without tuner enabled) shows an SWR of 2:1 on the
30m
antenna the K1 immediately reduces power to 0.1w and shows SWR 9.9. And
what's most stunning, the KAT1 can't even reduce this 9.9...
