Topband: Source for durable ladder line?

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 years we've found that the plastic spacers between the wires become brittle and break off. It may be

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 8:26 AM, John Kaufmann via Topband wrote: I'm looking for a source for durable ladder line for ma

Re: Topband: Source for durable ladder line?

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 matching transformers at each end. 73, Mike W0BTU On Sun, Jan 12, 2020, 9:27 AM John Kaufmann via Topban

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: zondag 12 januari 2020 16:27 Aan: 'topband' Onderwerp: Topband: Source for durable ladder line

Topband: Receive chokes

I have a pair of Pennants and a couple BOGS. The Pennants I dual feed. At each end I have a small box with a terminating resistor, relay and BN-73-202 binocular core transformer. I feed 12V through the RG6 which is all underground to select which direction. Without 12V the relay is not energized t

Re: Topband: Source for durable ladder line?

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 four lengths of 720 ft each for my beverage antennas, which have been in the field for four years, w

Re: Topband: Source for durable ladder line?

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-spaced Beverages. AFAIK, his club still has those Beverages up. *I no longer sell them. 73, Mike W0BTU

Re: Topband: Source for durable ladder line?

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 > On Jan 12, 2020, at 2:27 PM, Mike Waters wrote: > > The late Milt Jensen, N5IA successfully used t

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 -- From: "Marty Ray" Sent: Sunday, January 12, 2020 5:13 PM To: "TopBand List"

Re: Topband: Source for durable ladder line?

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 impedance. It is also a great source for very durable single wire Beverages with both ends connected to

Topband: Musings on multiple 160m QSOs

Regarding multiple QSO's I too am guilty. I will say that the contacts are short and have signal report. This is not to say I am not respectful of the new guys trying to work a new one. Furthermore, I spot DX frequently and post links to audio files collected on the reflector because I can hear

Re: Topband: Source for durable ladder line?

*Don’t* use the two conductors of a single run of twisted pair WD-1A as the transmission line - you’ll get a *lot* of loss in the transmission line. Instead parallel the two wires and run two lengths WD-1A (as Jim Garland says). 2 inches / 50mm spacing between them will give a line impedance o

Re: Topband: New Modes, Systems, etc

It's easy to appreciate why many people - who are passionate about the hobby - get upset about some of the things they see as being very negative to the hobby. Here in Britain there were LOTS of well-respected Amateurs who were actively involved in Jamming the VHF Repeaters when they first came o

Re: Topband: Source for durable ladder line?

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 the F/B ratio! One famous Topbander (Earl Cunningham, K6SE; SK) replaced his galvanized steel electr
