 That brings up the question, can you use a tightly coupled pair for a reversible Beverage? And would WD-1 wire work? http://www.signalcenter.com/commo/wire/wireinfo/wdwireinfo.html

It will. Confirmed in a number of installation. YMMV as always. Limiting factor is losses in this and similar lines. Affects only reverse/away direction signal level. Depends on particular Insulation

Yes, WD-1 can be used specifically with KD9SV's products available from DX Engineering. DXE also offers a FB quality two conductor alternative to WD-1. 73, Bob K3UL That brings up the question, can y

I use two lengths of WD1/TT (twisted pair), with the strands in each length twisted together. The two lengths are parallel, separated by about 4.5 inches, and threaded loosely through a hole in a cer

Thanks to everyone with some very good advice and good ideas I am now looking for a good place to buy the WD1-TT. I would like to get some even if I don't use it for this Beverage. I found one place

Fred, those transformers are the wrong impedance ratio for WD1! They are for 420-450 ohm wire. WD-1 has a much lower impedance. 73, Mike W0BTU _________________ Searchable Archives: http://www.contes

Mike , I think that WD-1 is 150 ohm someone on here posted that. So I am now looking over your.....Chart of turns ratios paper..trying to understand it. I maybe in over my head on this stuff...not re

Exactly, Dave! It's right in my Beverage antenna page ("145 ohms"), along with several different calculators. :-) And all WD-1* wire is *not* the same. Back when I used to sell Beverage transformers,

I've also heard that the native impedance a twisted pair of WD1A/TT is about 150ohms. In my application, I use two parallel lengths of WD1A/TT, spaced about 4.5inches. Each twisted pair acts like a s

I think you mean Zo, characteristic impedance. I haven't had any to measure, but that sounds high for any form of twisted pair. Twisted shielded pair audio cable is in the range of 70 ohms, a digital
