Hi All and a Merry Christmas. Just a quick question on the two wire Beverage as per Jeff Parker, KA1GJ http://members.cox.net/kb1gw/KA1GJ-Beverage.htm Am I correct in thinking that using two wires ve
Tracey, As I understand the principles of the Beverage both conductors should be parallel to the ground to work properly. The good operation of a Beverage depends on a process known as wave tilt. "Wh
No Tracey, one wire above the other works fine. Theorically it might work better if you cross the wires repatedly (the latter valid also for horizontal placement of wires). 73 & Merry Christmas _____
than It makes absolutely no difference. A twist however is slightly better, especially with wide spacing. I'm not sure what is going on with the transformers, but normally calculated turns ratios wo
I'd just like to thank all those who replied to my question on the two wire Beverage. The concensus was that vertically spaced wires will work just as well as horizontally spaced wires. 73s and Happy
I have a 900 foot WD1-A two wire Beverage that runs east and west and works well and has a great FB ratio on 160 and 80 meters. It is fed with a KD9SV box and reflection transformer for WD1-A telepho
Hello Herb, To me, this sounds like a termination problem. If the termination is missing (or defective), there will be standing waves on the Beverage and at certain frequencies it will act like a sho
I'm in the process of building a new two wire beverage control box to replace the one that Thor destroyed the other day. Fortunately the coax lead in was disconnected at the time! The top of the box
Ken, I would avoid any attempts to do relay switching by supplying voltage down a coax cable but rather use two coax runs. The relay, blocking cap, diode and associated circuit in my case with two DX
Like Herb is pointing out, one of the problems with stuff bought off the shelf (from DXE or others) is the lack of documentation. I have been waiting more than 3 years - so far without luck - for a r
Did the DXE board have a conformal coating applied? If it did not (which is poor design considering it is intended to operate outdoors), you can get small cans of the stuff made by Techni-Spray. I've
Feel free to check http://www.ra6lbs.ru/Papers/Bv_RA6LBS.ppt p. 10 and 13 to see the diagram, which is by the way a bit different of the DXE box. And there is no electrolitics of cource, the only sim
While I would never buy anything from DXE that I can do a whole lot cheaper Ive been running voltage down runs of CATV hardline up to 750' for Beverage switching for up to 22 years with no such probl

I believe that capacitor might be to help prevent a loud click in the receiver when the direction is switched. When the voltage is suddenly removed from a relay coil, there can be quite a pulse from
With that trick, you can switch four directions using only one single coax cable, two RBS-1P and another relay that is switched with +12Vdc and 9Vac. With 0V and -12V you control one RBS1-P, with 9Va
Thhanks Niko for sharing your experience with me. I did not find a reason why this takes place so I ran a separate 600 foot Beverage about 50 feet away and parallel to the two wire. The single wire w
My 2 wire Beverages are in the 500-900' range in the air and as BOG's and are used regularly on 30 and 40M with no meaningful degradation. However I wound all my transformers based upon the high RF g
Beat me to the punch. Too long together with transformer particulars can easily produce an unfortunate resonance effect that only appears in one direction in this configuration. Devil in the details.
