Topband: 7O6T Epilogue

Hi Gang While there is always more one could write about a trip like mine to 7O6T, it is time for me to shift focus once again to my other passion in ham radio - which is CONTESTING. CQ WPX CW looms and I need to start directing my energies there now. So I am going to make this my last.

Re: Topband: 2 Parallel Beverages

There's just one possible issue about all this that is conspicuous by its absence, as they say. At least in some installations, having feedlines going to each end of the Beverage supports is going to require laying the coax on the ground under nearly the entire length of the Beverage. And that's n

Re: Topband: 2 Parallel Beverages

Herb, Very common problem, with a simple solution. Ants are attracted to the magnetic field around energized wires. Turn off the power to your Beverages whenever you're not using them, and I'll bet the ants disappear. There ought to be one direction where no power is applied to the coax, and the

Re: Topband: 2 Parallel Beverages

Terro ant kill works well around here. If you cant elevate the RG-6 then find some surplus CATV hardline and remote the switching. There are low cost microwave relays that provide a wiping action that eliminates most switching problems; I bought 100 from Electronic Goldmine a few years ago at .

Re: Topband: 2 Parallel Beverages

Relays, switches, control voltage, cable power insertions etc. are all sources of problems in some climates. With DC running into a remote box I always find zillions of ants with their unusual defection all inside sealed boxes. Failure of DC switching has got to be higher than a Beverage wit

The bidirectional Beverage antenna was patented by Harold Beverage in 1922: http://www.google.com/patents?id=oN5iEBAJ&printsec=abstract&zoom=4&dq=1434984#v=onepage&q=1434984&f=false When Beverage built the huge RCA receiver site at Riverhead, Long Island, the Beverages were built as bidirec

Re: Topband: 2 Parallel Beverages

Mike, You are willing to run 2 coax cables and have 2 transformers, but don't want to bother with remote relays, etc. You could simply have a single wire, terminated at each end by a transformer. Run from each transformer a coax to the shack. Use a DPDT relay or manual switch in the shack to

Re: Topband: 2 Parallel Beverages

John, Yes, if both beverages are to be the same length, a single wire will work in both directions.  I take this approach on the E/W antenna:  It's a single-wire with transformers at each end and two runs of co-ax to the shack.  For this particular antenna, that was the cheapest / most-robust /

Re: Topband: 2 Parallel Beverages

Jeff, EZNEC confirms what you and Neil have found. Modelling Neil G0JHC's antenna with 1000ft beverages at 12ft and 10ft, offset by 30ft length-wise, shows almost identical patterns to a single beverage. Terminating both ends of the unused bev improves the f/b as one might expect, but does not

Re: Topband: 2 Parallel Beverages

I can understand why a fence would be a problem. Theoretically at least parallel Beverages should have no radiation/coupling. But that then means an absolutely perfectly balanced and terminated pair of lines. The closest I had a parallel pair was years ago and with Slinkys. After having one up

Like ZL3IX, I also had very poor results with a Beverage travelling too close to a fence. F/B was bad but even worse was coupling of noise picked up by the fence. WRT a second Bev on the same post, 12"-18" is far too close to space the two wires. I have several Bevs which cross at something o

Hi Mike, I have not tried to run two Bevs like that, but I have tried to run one close to a wire fence. The best F/B I achieved was about 8 dB. I would think that the two scenarios would be very similar. 73, Greg ZL3IX On 2012-05-23 06:20 a.m., rfman45 wrote: > > > > For various reasons I
