I have dipoles at home, no endfed stuff at the house.  I will have a 
chance to experiment with this on my next trip out of town staying in a 
hotel.  My plans then are to dangle the antenna out of the window, etc.

What i'm trying to do is just for use either in the woods or sitting in 
the car, predominantly in the car.  I have a preeeemo spot for operation 
at lunch time sitting on top of a very tall hill (there are no mountains 
in massachusetts) with a clear view of the ocean.  There is a large oak 
with a perfect branch sticking out about 60 feet above the parking lot 
surface.  I plug my portable rig into the cigarette lighter and pull the 
antenna up with the other end attached to a male BNC plug connected to 
the back of the radio.  The car is the counterpoise.


I wish I had the chance to use my portable rig when I was at the 
Mandalay Omni at Las Colinas (Dallas area).  I was on the 20th floor I 
believe.  Oh boy oh boy...
