I am looking for a Triex Sky Needle or US Tower MA series tower. 72-90 feet. Must be within one state of Florida. If you have one, let's talk. Bob W6TR _______________________________________________

Anyone know what the cable lengths are for the LM-470? Mine was manufactured in 1993 so it's fairly new. I am planning on recabling as I can see some rust on some of the cables. The 2 top sections do
Anyone have a legible copy of t6he schematic for the LM-470 control box? I am trying to wire mine up without the limit switches and my manual only shows the limit switch schematic and it is impossibl
Thanks to all that responded to my plea for help. It is now connected properly and it works fine. Next step is to recable the tower and dig the hole. Bob W6TR Valrico, FL ____________________________
Hi Doug, Your tower question brings back memories. I had (actually a fellow ham in the Rochester, NY area owned the tower and I put it up at my location) a 70' Aermotor tower. I put it up and took it

I am looking for a self-supported tower in the Florida or surrounding states area. My preference is a Tri-ex Sky Needle but a LM470 or a MA type tubular would also work. Please contact me off list or
I'm betting it is the same that Tri-ex used on the LM-470 and that is 3/16" galvanized and has 7 bundles . I think it is called 7/19. The nicopress would be steel or a alloy, certainly not aluminum.

Hmmm, seems like I said that about a week ago. I also said that SS is not as strong as Galvanized. _______________________________________________ _______________________________________________ Towe
Why does the LM354 use 1/4" when the LM470 use 3/16"? I've recabled 3 of these LM470 towers and the cable replaced was 3/16". SS cable is weaker and costs over 40% more. Bob W6TR -- Original Message
BTW, the specs on the LM 354 Tri-ex tower specifies 3/16" x 7 x 19 aircraft cable NOT 1/4". Look it up in Google under LM 354 Tower Specs. It is the first hit on Google. Bob -- Original Message -- Fr
