McMaster-Carr has perhaps the worlds best web catalog, good prices, quick shipping. You'll need to buy more than one or two. Fastenal has local dealers in many towns. Dick, K6KR Dick ________________

Someone suggested to me that I might increase the mast to clamp friction by wrapping the mast with something with a little bite. Do they make double-sided emery paper that can tolerate being wet? I h
I may have been that customer. When I initially installed my crankup tower (in a notch in the roof), the (relatively sympathetic) building inspector interpreted it as "attached" since anything more t
I've had very positive experience with Hank Lonberg, KR7X, Lonberg Design Group. If your tower permit application requires engineering certification, you may want to inquire about the licensing requi
I bought an extra rotator plate with a 3" + a bit hole drilled in it and a saddle clamp welded to the plate. The intent was to have something to take the lateral force of the mast bottom and permit t
1) Sounds like one or more of the relays in the box might be welded stuck, perhaps it was hot switched? Can you open the relay box and take a look? Pass a piece of paper between the contacts as a min
You'll get a lot of anectodal responses, including mine. I had a RigExpert AA-54 and loved it. I wanted one with a Smith Chart so I bought a RigExpert AA-1000 and also love it. I also have an Array S
This is a good point. Some devices are more suitable for carrying out to the antenna than others. Some have computer connections for extended charts and graphs. Its hard to recommend "best" without c
What I did was clamp a DXE thru bulkhead connector on a bracket to a tower leg near the top. It's a long barrel connector. Then I connected the rotator loop to that and a straight run from there down
I need to install a heavy ring rotator up at about 60' and the motor weighs more than I can lift easily with a rope, even with a 2:1 mechanical advantage. I could go to 4:1 with a lot more rope. I'm
Lightning aside, overhead wires will look terrible. Over the last couple years I have removed all the visible electric wiring put up by the prior owner of my property. Power came from a pole at the s

I would suggest "none of the above". I've used a 2-element quad and it played well, but I found it difficult to adjust and maintain. I've met a few people that really like multi-element quads, and th
At my last installations I chose option 1), and as I lowered the tower, I guided the coax bundle into a circle on the ground. I added an angular support to the topmost stand-off arm so that the weigh
I bought a spool from Home Depot. Dick I'm installing a k7nv prop pitch rotor in a few months and wanted to know what and where others have purchased their 10 gauge 3 conductor wire from? This will b
I use heavy wire for some of the rotator leads. In my case for a prop pitch, I use direct burial 10-3 Romex (and it's actually in a conduit). Heavy wire is expensive. Another choice is to put a 110VA
I?ve never run anything through conduit before. I have a 100 foot long 3? conduit between house and tower, and in that conduit I hope to run two ½? coax cables, three 3-wire ROMEX cables carrying 24V
This is great advice, Grant! I'm going to make a trip to the local electrical supplier anyway for goop and I'll get some tape as well. Your suggestion of using THHN rather than Romex is a good one. I
In my case it's primarily 1) and 4). When we bought the property we had a power line from the street to one pole, a sagging arc to another pole that was rotten at the base (it came down to about 5' a
