I've also changed my mind on using a SS whip on the top. 1" copper pipe
would be better, and easier to guy/stabilize.

Chris, a whip could however, be tied-down for streets with low hanging
wires!

Jack:

We're talking about a Semi tractor here.. It's already 13'4" tall, and
in order to get this antenna where it would do the most good, it would
have to be on one side or the other of the truck. Mounting it on the
front bumper would make me over length, and make it impossible to open
the hood for maintenance. Putting it behind the sleeper would raise it
another 3 feet, and allow it to couple to the exhaust stacks, not to
mention the back of the sleeper and the bulkhead on the trailer, and
would kill the signal even more, not to mention the risk of having the
trailer hit the antenna during turns, etc...

A whip will also blow around and change the SWR depending on how
close/far it got to/from the metal sides of the sleeper.

I think a copper pipe will do better, and be easier to guy and keep out
of the way.

Thanks
