I am new to this forum, but have been reading and printing a lot of helpful notes, and just about finished re-installing a Rohn 25G, ~46 feet. The first level of guys, using 3/16 EHS is up, and the l
Donald Thats a lot of questions. I will attempt to reply to the ones I know the answers too. More experts on this list may have more opinions. I am installing a similar tower right now, so this is my
My 1960s Rohn catalog shows the upper guys usually connected to the top of their towers. Current Rohn literature shows it down about 5 feet from the top. One obvious advantage of this is that it give
Fellow tower/antenna enthusiasts, I chronicled the details of my 45 foot 25G tower install at the AM Forum discussion group - since the main purpose of this is to support AM operation from some boata
I tried the local Fastenal franchise and they were clueless about guy wire stuff, including cable. They seems only intent on selling bolts. After checking various sources, including R&L, I found that
They are sprouting like weeds. Huge things. Today I passed several miles-long wind generation farms along I-40. I noted that about every 10th propeller was not spinning. And it was a windy day, const
Here is a franchise that is growing around the country. I went to the Albuquerque store and picked up some 6061 alum pipe for a project, good price,good service, I watched them cut it. This was on a
I still haven't invested in one of those portable units. i love my Delta Electronics OIB-2, that can measure the Z while 1 kW is transmitted to the antenna. Also, an Hp8751A network analyzer that I g
Exactly Bob. But I wouldn't want to be the one who has to run up the tower for short, back down to press 'SHORT DONE' and back up for open, down to press 'OPEN DONE'....you get the idea! I remember (
They have hand engraved X and R knobs, so the accuracy was very good. No microprocessor, and better yet, no power source, passive only. One can be carried to the top of a tower, not like an 8751 or 8
Rick I wasn't serious, tongue and cheek humor about calibrating a VNA for tower top measuring. Do you use phase stable coax, as you lay it down, roll it up or haul it up a tower, doesn't that shift a
I second what Rudy said, about using the screw in steps for poles. Deer hunters use these a lot in SC where I grew up, in their tree stands. I have climbed a few just for the view. The screw in steps
I use 3/16 EHS for the bottom guys, with strain (Johnny-ball) insulators, and the comparable-sized Phillystran for the upper guys for my 45 foot 25G. It was put up in November 2008, expecting 10 sq f
I have a permanent rope pulley in an elm tree about 22 feet up, that I practice rope ascending (for in-cave climbing, another hobby) with friends. Instead of leaving my expensive 11 mm static rope ou
I agree with all your points except for CPR and having a bystander to call 911. When you contact 13.2 kV distribution line, chances for survival are very slim. CPR isn't the issue, it is destruction
In addition to exothermic chemical reactions that expand in holes to crack rocks, there are some more proven techniques that cave explorers use when opening passages and moving rocks. Get a decent SD
I used a Sawzall to cut off a 25G flush at the ground, just where it came out of concrete. It was fast, and I could bend the blade a bit to make it flat as possible. Wear goggles, it happens quickly.
Yes I am, Steve. I was in South Dakota a month ago, helping to explore the 150th mile in Jewel Cave, 2nd longest in the world. I spend most of my spare time in New Mexico in Lechuguilla Cave, which w
About 15 years ago, I bought some spools of IP-8 Impervion, a Times Microwave cable that was RG-8 impregnated with a silicone goo that was supposed to prevent ingress of moisture and allow direct bur
I just sunk 3 8 foot copper clad steel rods for an electric fence counterpoise, using the handled fence post driver from local hardware (Lowes, etc). It is a steel pipe thing that has two handles on
