BELOW IS THE BETTER WAY TO HAVE DONE THIS MESSAGE...I MESSED UP IN
REPLYING WITH THAT LAST REPLY, SORRY...

Hey that's another great way to skin a cat!

WorldRadio (a' la the ham magazine) sells a 4 foot collapsible 20 foot
fiberglass pole... but it may not bend enough to get under the
overpasses...it's a tapered pole and about 1 or 1-1/4 inches at the
base...good for mobile/portable, though, I am sure.
