KU0DM,

I put up my first loop a few weeks ago. It's a 40 meter full wave at about 40' high fed with ladder line.

The bottom line is it's working amazingly well on all bands > 40, not so great at 40 & pretty crappy lower than that (but I really don't care about 75 & 80).

If you have the room, build out a full wave 80 meter loop, and you'll have a great performer on 40 & up. If you model it out, you'll see as the frequency increases, you start getting nice lobes forming off all sides of the loop in an omnidirectional patter. The higher the frequency gets, the more lobes form & they can give you some nice gain.

Here is a thread I've been writing in to discuss this antenna:

& here http://w9pds.org/loop.jpg is a pic of the feedpoint. I'm on a pretty small city lot but the loop just fits inside my property. It's damn near invisible & you would never notice it from the street unless I pointed it out to you. It is impossible to get a picture of the whole thing, it just doesn't show up on camera.

You won't regret putting one up. I'd like to hear your experiences if you do.
