I do close to the same as Gene does for my Trylon 72 ft tower. I use a cage of three wires held out about 2 ft from the tower with PVC pipe. See piks at link below. They terminate about 35 ft above g
Hey, brilliant minds think alike. But, I don't think you have the same high tech lid securing device that I use???!!! <vbg> C all on Top Band, Phil KB9CRY ____________________________________________
I don't think that the guys mean to burn your ears Mark. Your own remarks in your write-up on the website tend to steer us in that direction. You may have been lucky the past 5 years and/or the whole
Why go through the bother of engineering a rotating self supporting tower? You are certainly going to have to have a structural engineer bless any design. Personally I use a rotator and just turn the
Don't take this personally, but IMHO screw anchors are only to be used for a temporary installation. A 70 ft. tower is a sizable structure and needs adequate anchors, meaning, anchors that have concr
I'm sure screw anchors do have a place somewhere. And some folks have successfully used them to hold up amateur radio towers with antennas on them. However, and even if you use deadman concrete ancho
I'm getting ready to trench in a cable line to a new tower, and before I do, I'd like to mark where the existing cables are buried, particularly near the shack where they all come together. Any ideas
Correct me if I am wrong, but I had heard that terminating and tying each of the radials to a common bus line where they intesect it to be the prefered way now; and that is why Com Tek shows this met
I'm joining this thread late and have not read all the previous posts but the Titan Dx is 25 ft tall and per GAP, it does not require guys. That said if the desire is the guy it, 3/8 size rope is way
There is no such thing as a "2 pier pin" base. The Rohn flat plate for use with a pier pin installation is to be used with a single pier pin. These plates are not to be bolted down. I think you do no
Do a Google search on Fall Arrest Reels and you'll find many kinds. We use them at work and have them "permanently" mounted on fixed attachment points where workers routinely have to use fall protect
What I remember from my safety training (Plant Enginner & EHS Manager for major chemical manufacturing firm) is that when you fall without any shock absorbing device, the forces on your body (typical
This should never be done, period. The reason is, think about it, during a major energy surge event, tremendous heat may be present during large current flows and any kind of soldering/brazing/etc wi
DO NOT Solder (or braze or anything like that) any ground connections. NEC only allows mechanical or exothermic connections. (I wonder why?) As pointed out, CadWelds are NOT expensive and you get the
As can be seen from the info below from Wikipedia and from Erico, CadWelds involved much higher temperatures and a totally different joining process than brazing or soldering. This type of connection
Have you thoroughly read through the Polyphaser and ICE (Industrial Communications Engineers) technical articles yet? If no, then do so than ask your questions, please. Also a search through the Towe
IMHO Use solid bare copper wire to connect to the ground rods, #4 bare solid at min. No need to tie each legs' ground radial together, they're already tied together at the tower. Polyphaser recommend
I've had two hawks take up perch on my 120 ft. tower and 40M beam. Keeps most others away as well as squirrels and rabbits. However, I'm not so excited to make my annual inspection climb!! Phil KB9CR
I have a vertical on a large flat metal roof. Around the edge of the building is a lightning rod system using pointed air terminals and dedicated ground wires down the side of the building to ground
My shack is at the other end 72 ft. away. I intend on installing polyphaser coax and rotor protection devices at the bottom of the tower to ground. Do I also have to have the same devices at that end
