Well ??? G'day Indy ... and thank you for the correction.
I sort of thought it funny that Roger G0CJM was posting on
this subject...I had a thought he had a TANK or something
for some weekend hunting, or perhaps doing something else <g>.
So ... it is yummy egg..all over my face ... which reminds me
now that Rusty has me awake, it is time for breakie.

Indy ... I helped out , at a radio store in my youth, doing
installs in cars, and then came my first 18wheeler, and that
was a challenge. The cars were easy due to the supression
kits, and now I have found other places that sells them
since mentioning it before. The trucks were another story
and most of my installs had the radio mounted on or in the
dash < mostly on top of the dash> as well a few mounted
on the roof hanging down , to allow the driver to see the
radio while watching the road. All drivers in the trucks
had mounts on the mirrors and they had everything out there
with quick disconnects.

As mentioned, since then, there are now other sources, as
I noted them in two places I visited after posting that
info back to you. I will have a look at them and see where
they are, as well check out local drivers here to see if they
have this problem, and if they did, what they did to cure it.

Always insterested in this. I think most drivers everywhere
might be helped by this topic.

My pickup, as mentioned as a FORD F250 V8 460 and I changed plugs
to cutom type as well wiring and my Antenna and antenna deck were
on the rear bumpers < for RDF> with a few antennas in the cab roof.
I think Bob drives a car... and if a pickup...then it isn't
what a truck driver faces.

aaah yes ... like ...mmmm joy and a pain tooo....

Well Indy ... what can I say? When you mention the copper
pipe laying route, it reminds me of the friend I had who put
all his coax into a steel pipe going to the antenna.
Regarding the power feeder lines, they used to put that in
a soft shield material and that also worked, but then that
was then...not now. So I really think they would have a
better idea today how to end this maddness and frustration.
Hope after all your copper piping this does it ...or or...
mmm we'll all be hearing the howl from the outback.
I will try to do some looking into it today...and if I see
anything, I will post it, for all to look at, and I hope
your friend Bill VK4FW.
ttfn
Peter
