Pat,

I have had my Cobra Ultralite Senior up since May of 2004.  It seems to work 
best for me on 75 and 40, and I get good signal reports from just about 
every station I work on those bands.  The instructions recommend that you 
configure it as an inverted V, with the center at least 30 feet off the 
ground, but in my yard, the antenna is about 20 feet high at each end and 
sags to about 15 feet off the ground at its center.  For this reason, I 
suspect that it doesn't do as well for long distance as it could, but unless 
I figure out a way to raise the center up I won't be able to confirm that.

Although the antenna is supposed to work on all bands 80 through 10, I'd say 
it doesn't perform above 20 meters as well as I'd like to see it.  Maybe it 
would work better as an inverted V, but I have my doubts that it would be a 
great performer on the higher frequencies.

The antenna is made of a light but very sturdy wire that looks very much 
like three-conductor rotor cable.  The lightness of the wire has allowed the 
antenna to stay up in winds around 50 MPH.  It did finally come down last 
October during a freak snow/ice storm, but the wire around the center 
support looked weak so it may have been ready to break anyway.  After all, 
it had been up for over seven years, so I can't complain.

I'm not sure what other information you want about the antenna, but I'll be 
happy to answer any questions you have.

Steve
