1. Re: Topband: Error in ARRL 160 contest rules? (score: 1)

I beg to differ. The quoted statement inspired me to dig up logs from The Amateur Radio Club of The Ohio State University, W8LT, from 1973, which was the first year that I operated the ARRL 160. I f

Robert: Any 2 parallel wires will do, although matching probably helps to maximize the apparent directivity. If the unused port of the 2 wire Beverage is not matched, then the "other" port is lookin

4. Topband: Phased Vertical Arrays versus Phased Beverages (score: 1)

After reading ON4UN's book, looking at W8JI's web pages, and using EZNEC, one can demonstrate that an array of 8 phased verticals in a broadside/end-fire arrangement would have greater directivity th

Remember, the verticals are all very small (compared to a wavelength) and lossy, so one can assume there is no mutual coupling. The tophat is just 4 wires the same length as the vertical wire slopin

Part II of the project is to steer the beam, which would address that issue. Also, I don't intend to take down any Beverages yet :-) Vic _______________________________________________ Topband maili

Just enough to keep the branches from abraiding your wires to the point that they mechanically fail. I doubt you'd ever notice any affect on the performance of the antenna, so long as there is no me

I would vote for adding another instance of this very enjoyable contest format. Near one of the equinoxes sounds like a very equitable placement. I would also suggest collecting several ideas, and th

I try to listen on the Beverage that points in the direction from which I hope to hear some DX. Then I tune around with the RIT to make sure the ESP isn't manufacturing a signal. If its a mixed dome

I've been building phased arrays recently, and I too have been measuring the velocity factor of RG-6. Some Belden 1189A used for end-fire phasing lines measures 83%, which is consistent with the dat
