Hi Tim,

Here's how I did it.
http://www.w0btu.com/Beverage_antennas.html#transmitting_on_a_Beverage

I left the termination resistor off, and it still had a 5 dB F/B ratio.

I also connected the two wires at each end and added a few extra radials.
It surprised me how well it worked on 75 meters and up. It was fun to try,
but I wouldn't recommend trying to win any contests with it. :-)

73, Mike
