I do about the same but welded a 1/8", 6 "X 4" flat steel plate to the middle of the mast side of the angle stock. I mark the center of the angle/plate then drill holes about 4 inches vertical apart
I ordered and received two 3PDT switches that I ordered from ebay. They have the spring loaded center off position. I want to use one of them to replace my up/down switch for my old motoroized Trista
Tnx to all who replied. I'm going to purchase a larger switch from Mouser.com that should handle the current. Ray, N6VR _______________________________________________ _______________________________

I recently acquired two 100ft rolls of Andrew 3/4" hardline that I will be using soon. One is LDF5-50, the other is LDF5-50A. I have searched the Web for rating of this coax and the types of connecto
Tnx for the replies so far. I now realize that I am talking about 7/8", not 3/4" hardline. The L45U is not a standard type PL259 connector. It is much larger and has an inner, circular brass ring, it
Speaking of cable pulley bearings, if you care to replace one yourself, instead of paying $80 or so for the pulley and bearing, they (the bearing) can be purchased usually NIB on eBay for $10 - $20 e
It looks like a Japanese Create 15ft'er. I have one much like it and have a one page brochure on it somewhere, but I'd have to do some looking for it. Do a Google search on Create, or Create Towers.
Bill, If you have a schematic, you can see that the center of the rotator motor is grounded as well as the center of the indicator pot. They both go to pin 1. The other bigger wire goes to the brake
Take a look at K5FD site: they have a 12 wire version. http://hr-micro.com/index.html Ray, N6VR _______________________________________________ _______________________________________________ TowerTa
I've witnessed two such failures, both were on older Tristao towers. The first happened during the hayday of the N6DX Mallibu hilltop contest station. We were raising a 72ft Tristao tower using its e
I've been using 30 ft pieces of 2", 3 " and 4" irrigation pipe for30 years. Its cheap (used) and very light. It is not real strong so I guy it twice with dacron. The only difficulty is making the red
I am rebuilding my 35 year old KLM 4 el yagi to put back up at my new location. I was very pleased with its operation as assembled using the 70's - 80's manual. The original design of this yagi was d
Thanks to those who replied to my question about upgrading the old KLM 4el 40m yagi. Apparently, there have been no computer models generated to improve its gain or F/B. It is dual driven element so
Hello Mike, I buy the matching connectors, body, pins, etc from Mouser. They have everything! The corresponding female body PN is at: http://www.mouser.com/ProductDetail/TE-Connectivity/206708-1/?qs=
Several people asked for the Mouser parts to build HyGain/C.A.T.S. rotator quick-connect connectors. The information is below in TXT format. I hope it works. If not, I will ask a friend to place it o
Rich, I think Tashjian Towers has them, but they are expensive. Over the years I have pressed out and replaced a half dozen or so of the bearings from the pulley. They are probably K8 or KP8 bearings
Rick, Do an eBay search on KP10 bearing. There are about 20 listings varying in price of $20 to $40. eBay is where I bought my spare KP8 bearings. GL, Ray, N6VR ______________________________________
I've had only one case where the aluminum pulley itself was damaged. In all other cases, when the bearing froze, the whole pulley assembly rotated around the bolt holding it in place. Take a look at
It is always best to "control" the fall with a lowering device, crane or whatever. I have dropped towers onto a 3 - 4 stack of large used tires. They will take up most of the fall shock, but one time
