I'm looking for a source for durable ladder line for making two-wire reversible Beverages for use at the KC1XX contest station. In the past we've used the line sold by DX Engineering but over the yea
Other than measuring some of the stuff years ago I have no real experience with it, but you might look here: https://thewireman.com/product-category/feed-lines/ladder-line/ Wes N7WS On 1/12/2020 8:2
I don't think you are going to find any, John. I had to make my own. Is that something you are willing to do? There are several options for that; most using wider spacing which requires custom matchi
For more then 10 years I use 170 meter long runs of 300 Ohm from www.dx-wire.de. Very small size and very strong. Pe5t Verzonden vanuit Mail voor Windows 10 Van: John Kaufmann via Topband Verzonden:
John, I had exactly the same experience as you with the DXE 450 ohm ladderline. After two frustrating years of repairs, I finally switched it for WD-1/TT mil surplus field telephone wire. I now have
The late Milt Jensen, N5IA successfully used that wire. It takes custom matching transformers (which I made for him*), but he told me that those Beverages worked just as well as his other, wide-space
Interesting. The parallel lengths of wd1a on my beverages are spaced about four inches apart. I use the same DXE matching xformers I used with my DXE ladderline. 73, Jim w8zr Sent from my iPhone ____

I make my own. Using the WD military wire, black zip ties, and tube insulators from Tractor Supply. It is pretty indestructible stuff. Also looks decent. 73 Bill K3SV I make my own ladder line: http:

Probably the most durable two conductor is Military WD-1A telephone cable. available on eBay for $50 for about a half-mile. Special lower impedance transformers are required to match the line's imped

Exactly how much is "a *lot* of loss", Jeremy? Too many knowledgeable Topbanders have used it over the years --with great success-- for it to have enough loss to matter. Extra loss can even improve t
FWIW, other than my HI-Z Rx antennas and my 6M Yagi, all my antennas are WD-1A 73, Gary KA1J _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
we do not use WD-1A wire for our 2-wire beverages @CR3W any more as the attenuation of it (used as a 2-wire-line) is even higher than that of RG-58... we use 180m of the 300 Ohm flat line (of DX-Wire
Theres a good thread on this here: https://topband.contesting.narkive.com/GKD4HWdS/topband-wd-1a-2-way-beverage We have some remote beverages fed via about 700m/2400ft of low loss coax - around 6dB
