I've been reading about these and am intrigued. These antennas are often mounted in a sloping configuration, but how steep can the angle be? I'm sure the steepness of the angle is going to effect the antenna's radiation pattern, but will how? Does it cause the antenna to become highly directional as the angle increases? Actually, the idea behind the slope is to make it more omnidirectional. The ideal slope is something like 30 degrees, but there's no hard-and-fast rule on this. Set it up as best you can. How do these antennas perform in relatively noisy environments? I've read that they're relatively slow to pick up local noise, but I'd like to hear about some people's first hand experiences with them. I absolutely love mine. Or loved -- it came down and was heavily damaged in a windstorm, so I've been stuck using an end-fed wire instead. It seems to be far less sensitive to near-field noise than the longwire, and yet had nearly the same signal strength from most directions. The longwire is 400 feet long and has an extensive grounding and radial network, so it's not exactly a slouch in the receive department... but the T2FD was a better overall performer. I just have to rebuild it now. Are these antennas inevitably eyesores to those philistines who don't appreciate the beauty of a good antenna? Is there a way to make them less conspicuous? Mine was quite visible, and I thought of it as an eyesore, but my neighbors didn't even notice it. It is heavy, visible, and provides a lot of wind loading with all the spacers it needs. I live in a *very* high wind area and mine would always come down. I ended up with a counterweight system to allow it to get blown out of shape by quite a bit and then return to normal when the wind died down... but that may not be necessary where you live. I don't know of a good way to make them less conspicuous unless you want to play around with using very high strength material with a dark color for the spacers -- something that doesn't have to be too thick. Mine used PVC spacers and was ugly, but I live in the boonies and could get away with it. Thanks, Steve Hope this is helpful, Eric -- Eric F.
