Topband: WD-1A Dayton
I need to buy some WD-1A ex military telephone wire. At least one and preferably two 2km (6600') drums. Or possibly more smaller reels. I wonder if anybody has any that they would sell to me and could bring to Dayton? Obviously I am happy to pay the going rate. Please contact me privately. Thanks in advance.

Re: Topband: WD-1A wire
Roger I run my four 900 foot beverages in parallel (E/W and N/S) with WD-1A. They are generally about 1m apart, but the N/S beverages are much closer than that at various points. They also pass through electric fence insulators and I use cable ties to attach them. The wire is very strong; more so than the wooden posts and electric fence insulators. It is those that break if a cow decides to have some fun with the beverage. I have had instances where cattle have become tangled in the WD-!A and pulled it across the field. The wire does not break. It just pulls out from either the termination or connection boxes. 73, Ian G4IIY PS It's a right pain to untangle 900 feet of WD-1A -Original Message- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of Roger Parsons via Topband Sent: 08 June 2015 14:44 To: Topband Subject: Re: Topband: WD-1A wire Thanks for all the replies received both direct and on this reflector.

Re: Topband: WD-1A wire
And if one needs a heavy duty solution for installations with a folling branches and trees then 2 of WD1A at your favorable spacing is a good choise 2 x WD1A 500 mm apart is very close to 800 ohms and easy to match 2015-06-07 23:09 GMT+03:00 jeremy maris jer...@maris.plus.com: Yes WD1A works very well with the conductors strapped. I've built a 300m long reversible beverage up at about 2.4m with two parallel runs of strapped WD1A about 50mm apart. Impedance of this line is around 450 ohms at that spacing so transformer design is simpler than one twisted WD1A and losses considerably less.

Re: Topband: WD-1A wire
I'm amusing WD1A for a 900 foot East Beverage and its performance is awesome allowing me to work VU4KV, E30FB, and EP6T with good copy. The same antenna in the reverse direction is not so hot compared to a singal wire 600 footer. Don't know why but there must be some simple explanation for this.

Re: Topband: WD-1A wire
I've used WD-1A wire here for years for my Beverages, which are all over 600' long. The receiver preamp handles loss OK in the forward direction. In the reverse direction I use a W7IUV external preamp due to extra signal loss. This is no problem on 160 or 80 meters. Be careful with this wire, as if the insulation gets scraped somewhere along the antenna the iron core will rust through and the copper wires can then open. This has happened to me on several occasions. Dave, W5UN On 6/7/2015 4:40 PM, K1FZ-Bruce wrote: A lot are using it Roger, The I squared R losses are low because signal currents levels are so low..

Topband: WD-1A
I use several 900 foot reversible made from WD-1A and found this as a good solution and a good price for wire itself. I use the KD9SV boxes that Gary designed. My big problem is that I have huge 2500 foot roll where the cardboard core disintegrated leaving a mass of tangled WD-1. Maybe someone has an idea on the best way to unravel this without cutting it?

Re: Topband: WD-1A
If you're lucky, you might be able to grab the innermost end of the wire and pull it out of the center of the coil (I'm assuming your rotted-away reel left a coil of cable). There are actually commercial pull-out type packages of wire made similarly to this. The wire will come out with extra twists in it though. If that doesn't work I think you're stuck with a lot of untangling work if you want to make use of the wire. -Bill I use several 900 foot reversible made from WD-1A and found this as a good solution and a good price for wire itself.

Re: Topband: WD-1A
I purchased from surplus, six each of the larger 3 foot diameter reels of WD-1A a few years ago. One of the reels was damaged by the freight company and all of them have not weathered well in my storage area. I am in the process of using from the broken reel and have set up in the following manner to single handedly unspool the wire without tangling. With the reel laying on end, the other end is removed so the reel of wire resembles a spool of thread on a sewing machine. I used a tripod with a 5' extension pipe placed along side the reel to hold a loop made of #6 solid copper wire over the center of the reel, about 3 feet above the center of the reel. The outer loose end of the reel of wire is fed upward, through the loop of wire held by the tripod, and then outward to where I set up a take up reel to roll off the amount of wire I require for the current project. In this manner the wire unspools readily without any complications. It does have the twist representing one twist per revolution of wire unspooled. For me that has not been a problem. I am currently using WD-1A for 2-wire Beverage experimentation AND for radial wire under antennas at a new 'vertical farm'. Another method of paying out the wire I may pursue for the other reels as I use them, or respool them, is to make a heavy duty lazy susan. A heavy duty, light friction bearing, such as using a wheel housing from a dismantled vehicle, would be required under the 'table' upon which the reel of wire would be placed. I am sure there are other methods.

Re: Topband: WD-1A
Great idea Bill. Unfortunately the yard man, every time he would cut the grass with a string trimmer he would pick up the mass of WD-1A and move it to another spot. it is in a Gordian Knot that would even be a challenge to Alexander the Great! 73, Herb, KV4FZ On 7/23/2012 10:47 AM, Bill Wichers wrote: If you're lucky, you might be able to grab the innermost end of the wire and pull it out of the center of the coil (I'm assuming your rotted-away reel left a coil of cable).
