I've been offered a quantity of CATV 75-ohm hardline. The radio room will be about 120 feet from the base of the tower, and the highest antenna on that tower will be at 77'. The antennas on this towe
I?m planning a tower installation that requires six guy wires (three pairs of two) at the 50? level. The guy lines will be about 75 feet long. I?m supposed to use some combination of 6700# Phillystra

I find LMR-400 a bit stiff for a rotator loop. You might want to use something like LMR400 Ultra Flex or BuryFlex for the loop. For my 200 foot run from the radio room to the junction of the rotator
I have never personally installed rebar. My tower and guy anchor foundation drawings specify a "mat" of #5 (5/8") rebar , 5 rods each way, top & bottom, just below the top surface and just above the
Well in my case, I contacted the engineer, and he suggested adding 9 vertical rods tied to the mats to suspend the upper mat over the lower. Rohn catalog descriptions aren't sufficient for my county'
Welding can reduce the fatigue life of rebar. It would be difficult for an inspector to verify your "minimum amount of heat". How much heat would that be? How would an inspector verify the adequacy o
I have no special expertise to advise you. I'm planning to include such a device in my next (pending) construction. We have a lot of electronic devices in a modern home and the prices add up. I think
What I have heard so far is: 1) I can get the tower down by removing the safety guard and the v belt and turn the wheel by hand. It will take a long time to do this. Down is much easier than up. Be c
I want to thank all the people that offered advice, particularly W3TX who observed that if it stopped "eorking" I should ask for advice from Winnie the Pooh. Fat fingers on the iPhone and too little
I thought a well-aligned V-block and a drill press would be just the thing to drill the holes straight. Two drill sizes is fine with me... Nice summary! 73 de Dick, K6KR If you get on an airplane, yo
I'm planning to do something like this. I plan only one thrust bearing, at the top, but I plan a second rotator plate (I'm ordering from Custom Metalworks), with a hole slightly larger than the mast,
Although most of us can rent an excavator at a rental place and learn the basics in a short while, this reminds me of getting your college buddies to help move furniture - it might be quite expensive
Hank has prepared permit diagrams for my towers, I can also recommend his work. Island County approved the (hefty) permit applications with no additional to-and-fro. Hank and and I had several rounds
It might depend on what state you live in. Shipping costs and tax might be a significant factor. Dick, K6KR What's the best source for buying LMR 600 coax online? ____________________________________
I think you'll notice the performance improvement of a directional antenna at an appropriate altitude vs an omnidirectional vertical much more than you'd notice the difference between almost any two
I've acquired a used TIC General TIC Ring model 1022. It came without many nuts and bolts, so I'm going through the assembly manual and making up a hardware shopping list, consisting mostly of hex ca
I find myself without a drift pin to align the leg holes in Rohn 55G tower sections (5/16? bolt size). I need to pull together several sections on the ground with a couple of come-alongs. We plan to
Klein Tools 3256 (10" broad head bull pin) has a 1/4" point. That looks like the right one... Rohn 55G tower section bolts are 7/16, so a 1/4" point looks about right. Thanks! Dick, K6KR --Original M
