Something I forgot to mention - don't laugh.

How about a high speed/small wing kite to get the j pole up 20ft or so?
If you get out of range just let the thing stream out behind and above
you for greater range.

The greatest height a car/truck can be on the highways is 13'6". Mount
the ant on a lightweight fiberglass pole with the tip of ant at this max
height?

Thanks for all the responses and tips .... It has to be practical as well
for use when moving at speeds up
to 100 to 120 mph ( not operating at this time) without breaking off (
German Autobahns) as it won't be
possible to stop, remove and stow it safely when motorway/autobahns are
encountered.. and also not
attract unwanted attention from the authorities who may think it is an
unsafe attachment if too big.

Sorry for barging in again Nick! This isn't directly related to your Q.

I guess that you are using the system for general comms as well a
safety. One of the features I think is available using DCS on some
radios is the ability to poll for the other station. The equivalent of
"are you there?" without actually speaking into the microphone.

This feature would be very helpful for safety issues as you at least
know if the other station is in range or not. Cresting a hill at the
same time for example may give you range you wouldn't normally consider
as viable.

This may even be able to be automated to the extent where you can poll
for the other station every minute or so.

I have never done this myself so don't know the full details. There was
a nearby station though that used it regularly to poll his local
interest group. My horrible old VHF/UHF gear is nowhere near as new
fangled as that! grin

Yes, we have that feature - using FT-60s at the moment but if we lose range,
we immediately go to high power and
if that doesn't work, stop at the first opportunity and use the cellphones
to report where we are ( each has GPS )
Never had to use it yet though but that's the back-up plan

FMI interest John which country? (Although I guess it would be similar
worldwide)

I use to guy a mobile fiberglass pole for that purpose. Was ecstatic
over the performance until I smashed some low service station lights..

Bob:

USA here. Yes, I have gotten used to watching for low overhangs when
using the fiberglass pole. I have one I got off ebay, it is hollow and
about 1-1/8 od and telescopes. This is handy for having the vhf/uhf/shf
at any height one wishes ...

You are quite right though, 13'6" may only apply in USA. That height is
established by big trucks, they can't put overpasses lower than that or
the trucks can't get past--and everyone needs the privy paper, now don't
they? ;-)

Warmest regards,
