Weird Mobile Problem
 
You obviously don't have a common ground. The only 'ground' you have is
from the antenna mount, via the coax shield, to your radio. When you hook
your ground post to the chassis you have extended the 'ground' and caused a
higher swr.

Try running a ground strap to a common metal point on the vehicle...if you
can find one these days. Check with ohm-meter and make sure as much of the
car as possible is connected together.

Of course you will probably have to retune the antenna now.

Hi:
I have suddenly developed a weird mobile setup problem. When
my IC-706 is in the car and antenna (HF) is hooked up, everything is
all is ok ie swr. But when I hook up the ground wire from the frame of
the car to the ground post I now get get high swr. I have checked the
antenna system with an analyzer and it appears ok. Any idea's???

Hi:
Probably beneficial to clarify something, the antenna is a Hustler
attached to a 3 magnet mount type system. This type of system has
no physical ground, only capactive type ground.

Why, Dan, you actually know what you are talking about this time!
Inhaling those nerve gas remnants has apparently caused your synapses
to reconnect in ways that lead to valid insights into RF problems.

Next, you'll be registering as a Republican.


Dang, I didn't mean to show off. Didn't mean to ruin my image, and all
that. And BTW I'm not registered but I vote mostly Republican.

Changes nothing, just enhances the problem. My info is still accurate. If
you want to continue using that 'mount'. Fine. But you still need to
GROUND EVERYTHING on the chasis of the vehicle. That is STILL the problem.
Strap it all together.

You could always eliminate the middleman and give your paycheck directly
to people who don't feel like working. Then again, the politicians
would be out of a job of skimming the cream off the top, and they would
join the ranks of people who you would be giving your paycheck to. Oh
wait, they win either way!!! Who makes these rules? Oh, wait!!! I'm
starting to understand.

But to keep this post in line with the rules,...

Here in New Hampshire, I've noticed that there are places between
mountains that we lose cell reception but VHF/UHF is fine, and vice
versa. And 6 meters is almost always better for hilly coverage. The
state police still use low band (46 MHz or so). Anyone else notice in
hilly states (Tenn, Calif, etc.) have more 6m repeaters than usual?

Not these days. After the Demoncrats fielded Clinton Gore I guess Im more
of a anti-democrat.

Quite a common thing Dave. In fact ten meter FM is even better in hilly
terrain. The higher the frequency, the smaller the wavelength. Thus it is
more subject to scatter, reflection, absorption, etc. However in some cases
you will find 70 cm is better for the urban city invironment.
