[TowerTalk] Low loop in a sloping configuration

I'm curious what you desire to achieve from such an antenna.  It's not 
likely to be an improvement over what you already have.

A few years ago, before I was able to put up my current tower and yagis, 
I suspended a 40m diamond-shaped loop from a 55 foot tall pole ... 
sloped toward Europe from here in Arizona and fed at the bottom apex.  
It worked OK, mostly because I live on a steep hillside facing Europe, 
but in my opinion it didn't offer anything special other than it was 
also possible to use it on other bands with a decent tuner.  Keep in 
mind that unless you feed it at one side for vertical polarization that 
half your current distribution is going to be pretty close to the ground.

In my opinion, you'd be better off stringing an Inverted-V from the top 
of your tower if you want something horizontally polarized to complement 
your existing verticals.

I was wondering if anyone has tried this before and can offer some first hand experience or can offer some educated guesses (or even EZNEC analysis) on the expected performance. This would not be the only 80m antenna, it will supplement full size a 4SQ and short verticals RX antennas.
