Hello Kevin-I have built a few of these antennas over the years. Mostly for 1.2ghz RHCP tx and 2.4ghz LHCP rx for a dish feed. As mentioned the polarization is fixed. The helix antenna is pretty broad banded. I never built one for 70cm or 2m however I have been tempted. Here it comes....Our next HEO will most certainly have L & S band capability. I can only hope I will last that long. If you want some pics I have many. Yeah they do look cool.

Hello all, whats the take on these antennas? I am sure someone on here has used them and they certainly look cool but how do they perform?
Dont you have to switch polerization on a cross polerized yagi?
I know there is not a perfect antenna, just wondering about the Helicoil...
