Tom,

Yes, I use the Cobra with my amplifier, which is how I run it on 20.  For 
that reason, I bought a balun capable of handling 1000 watts.

I've got the antenna 20 feet off the ground at both ends, with no center 
support, so it sags to about 15 feet at the center point.  Not the ideal 
setup, but the best I could do at the time.

Steve
