Has anyone restrung the cables on a Triex 90 ft Sky Needle, or know of someone who has? I will be putting one up in a few weeks but need to replace the lower (main) lifting cable since it is damaged.
Wayne, One upgrade is to use copper clad steel wire for the element loading wires. However, F12 sells coils to replace the element loading wires. There have been several discussions over the past yea
Does anyone have engineering data and/or drawing for the US Tower TX-455? Especially need the detailed concrete/rebar base info to satisfy the County. I'll pay for any copying and shipping charges. T
Guys, Thanks to all who have responded. NR6M was able to find the all the necessary info on their site, he's putting up the tower. Info is attached. Tnx agn, Ray, N6VR On Thu, Aug 1, 2013 at 3:44 PM,
Denis, Look in the Mouser Electronics catalogue: http://www.mouser.com/<http://www.mouser.com/Search/Refine.aspx?Keyword=625-1.5KE82CA-E3> The diodes used in the Green Heron rotator controllers are:
I'm in a dilemma. I purchase a used TM-490 90 ft Sky Needle and recently found some of the 5/16", 7 X 19 aircraft cable lifting cable strands broken. The tower is on the ground and not been in the ve
Grant, This is the kind of information I was looking for. Thanks for taking the time to find it! With the comments and info received so far, I am more convinced now that my only real option is to rep
John, The pull down end of the lifting cable is bolted internally to the bottom of the 3rd section. The only way to get to it is to separate the sections. On later versions of this tower and on the 1
Ray, I had a TH3 and it did not look like yours. I'd say its earlier that the Hygain TH series??? Those insulators are Hygain. Ray, N6VR _______________________________________________ ______________
Has anyone come up with a way to connect flat copper straps to ground rods? DXXE sells copper clamps w/ hardware, but at $35 a pop, I hoping that there is a more reasonable way to get the job done. M
Kirk, There were a several of ways mentioned. Here is a brief summary: 1. Silver solder the copper sheet to the ground rod. Must use a high temp flame source such as MAPGAS or acetylene. 2. Use a "U"
I have an older 90 ft Triex Sky Needle that I have been working on. I'm down to the wiring of the raising/lowering motor. Because of the long distance, I ran four conductors (250 ft) of #10 wire. The
I used an acetylene torch to ignite my one shot plus Cadwell charges. It worked fine. It took about 3 - 4 seconds to ignite each one. Propane and Map-gas were not hot enough. Ray, N6VR On Tue, Nov 5,
The subject of bundling tower coax with a spiral/twist type material was recently mentioned. I cannot seem to find it. I would like to bundle my coax and other cables, hanging from coax arms, to prot
Tnx for all the responses. It seems there are several "Split Loom" tubings available. So far I am looking at: http://www.elecdirect.com/catalog/b2b3f81d-7478-43aa-834c-7ba122bd45d2.aspx . This produc
I am using a K7NV prop-pitch rotator for my almost completed tower project. For the encoder (magnetic pulse counter) that is mounted inside the PP motor, I am using a 2 pair small wire cable that has
Mark and All, I have no problem grounding the foil and ground wire in this encoder cable. I am puzzled though, inside the Green Heron Controller, each terminal lug going to the PP and encoder has an
I filed a claim on a wind damaged 2 el 40m yagi years ago in Calif. Insurance paid for its replacement, however, my next years home owners insurance premium almost doubled! I dumped them and found an
