Hi Rich, I have been using a GAP Eagle for years, and it resonates in every band as advertised (which is not to be mistaken for works miracles in every band). Sure, any small antenna like this is going to be a compromise. I was actually pleasantly surprised by the performance on 40M during the RTTY Roundup last weekend, I expected the Eagle to pretty much suck wind compared to my old full-size dipole, but it compared very favorably. It comes with its own ferrite choke (aka 1:1 BalUn) on the pigtail lead coming out of the bottom. Over the years and with wind, that has chipped and broken, but replacing it returned the original performance. I've got the GAP-supplied ferrite choke protected with heatshrink tubing, and the whole thing secured pretty well to the mast, so I'm hoping not much will flop around and it will last a good long time. By the way, I did have it elevated 10 feet up - this makes a difference. I've got it at the same spot as my old Cushcraft R5, a 10-foot mast on the porch roof secured to the main roof rafters so the mast sticks up about 3 feet over the main roof, the base of the Eagle ending up about 30 feet in the air. This basically is the only spot I have which is both reasonably accessible in case I need to fiddle with the connections and a good distance (at least 20 feet) away from major metal like power/phone lines, etc. It's also just about the midpoint of my lot so I keep the radiation as far away from my neighbors as possible;I figure that has to help with RFI and also helps me do the radiation-exposure self-evaluation with a clearer conscience.
