Rotating it had no effect at all on signal strength. I tried it on 2M and couldnt hit the local repeater with 1 watt normally I can reach it with 100mW. I would say this classifies the antenna as a dummy load. no, i am waiting for the final tweaked design. *if you have built one to art's specs then you are probably measuring just the side/back lobes, which is a very good sign. *if it has a pencil beam on 160m, then by the time it gets to 2m the beam will probably be so thin that it will be like a laser beam, so you'll have to be pointing it VERY accurately on the repeater. *so go rotate it again, very slowly and carefully, and don't forget to aim it in elevation also! LOL I just built the thing out of boredom and the effects of having a really nasty cold. It was obvious that the only radiation to speak of was coming from the coax. I actually heard some pretty strong signals on 11M with it. They were also very non-directional . When I shorted the ends of the feedline together and connected it to my tuner it may actually be mistaken for a viable antenna working about as well as 20 or 30 ft of wire hanging out the window hearing signals on 80 40 20 and 11. It wouldnt suprise me if Art never even built the thing. JImmie |
