My father uses a TS 50 and an IC901 in his taurus.  only noise is slight alt whine
on the 901.  Only effect caused by xmitting is changing the speed of the key-in-ignition
chime when xmitting on 440.  He's happy with car.

Of course I hold onto my old 71 VW bus.  Point ignition, generator, etc. all waay in the
back, entire body grounded, lotsa room for rigs, etc.  I'd hate to lose that car!

Subject: Ciruclar Polarized Loops
To: [e-mail]

I was just building a loop antenna from down east microwave and started
thinking:

IF the driven elements were arranged to be CP and the parasitic elements were
attached to a nonconductive boom then this would seem to be a great antenna
for all around use.  A 3 db gain loss from linear to CP would be realized but
the antenna would be much more flexible.

Anyone ever heard or tried this.

Thanks,

Greg

Thanks to those who replied to my earlier message about portable yagis...
so what it looks like is that I want to make one of these "arrow antennas",
if anyone could post the plans it would be much appreciated :)

    With old style Corvettes, I once mounted an antenna in the
flat rear deck. To provide a groundplane, I mounted old aluminium
litho plates under the fiberglass with double sticky tape (The
industrial strength type for carpets). Then I drilled the hole for the
antenna. Worked like a champ.

    Just make sure you use a big enough litho plate to provide a
1/4 wavelength round the hole.
