Of course at low tensions the difference is large. As you tighten the cable, the cable stiffness becomes less of an influence. I'm looking at the chart for my Penn-Tech TM-800. For the wire sizes whe
If your tower is the equivalent of R25, and only 30', there's not much you can do to it to really overstress it, unless you try real hard. But if you really want it straight AND plumb, consider diggi
Douglas, Oh boy, at the risk of getting all the engineers and lawyers and would-be's in a dander, I'll suggest this - with the caveats that I don't really know what kind of tower sections you have ot
I've used that method myself on towers that had suffered vehicular damage near the base, works well. In fact another option for Doug, if he's going to be forming up a new block of concrete above grad
Chris, The forum police have already decided that the thread is closed, so I doubt very seriously that your prediction is correct. BTW, you are in violation sir :) -Steve K8LX Heck, I'm one of those
Hill Radio normally has the best pricing on Rohn 25-45-55-65. -Steve K8LX On a similar note, I am going to install a 150 foot tower ( need to get over tall trees) in South West Oregon. Could someone
A good alternative to schedule 40 pipe is the tubing used nowadays for fence top rails, known as SS40. It's lighter (thinner wall) but stronger and actually less expensive than galvanized sch. 40 pip

I'm guessing that the number on the cable is a US government contract number. Also that the cable is real Commscope RG6 type 75 flooded CATV coax, and that you have nothing to worry about. But did I
There are two items on Max-Gain's web site that you may be interested in. Stock No. 9100 is a 4 hole bulkhead connector for Bird line sections that is about .25" longer than standard. Stock No. 9935-
I've handled many hundreds of reels of Heliax over decades, and never worried much about that warning, which has more to do with creating egg shaped cable (from the weight of the upper layers) than t
Agreed that the main concern has been transportation and rough handling. Fork lift operators are evil people. AVA with it's thinner shield is more prone to fork damage for sure, but it's lighter weig
It's surprising how many commercial towers do not have safety climb systems. I'm talking broadcast towers, cellular towers, you name it. A wild guess around here is 3-5%. The first man up double hook
It shouldn't be a problem to install one on a rotating tower - the safety climb would rotate with the tower. If I wanted one on a tower with ring rotators, I'd probably run it THROUGH the rings (in t
Actually the two scenarios are the same - the safety climb needs to be run inside the rings and you must bite the bullet at each ring and do a little hooking and unhooking. Still relatively easy to m
I mounted my rotator at the same point in 45G and had no problems for >10 years with the antennas/wind speeds in Colorado described previously. If still concerned, you could mount a straight 25G sect

I've been gradually converting to all DINs everywhere that it's reasonable. Why? Are all your systems at UHF? No. In my business we use nothing but 7-16 DIN nowadays and it does not take long workin
You make a jumper with a DIN on one end and a PL259 connector on the other. Or you order a custom made jumper from any number of places that do that, like DX engineering. -Steve K8LX I've been gradua
Here's what I know - or believe I know :-) For LMR400 style cable THEE best DIN connector is the Comp-DM-400, formerly PPC brand but apparently now made by RF industries. This requires a special comp
