I have always put the pea gravel in the bottom as spec'd by Rohn. The way the legs are constructed and assembled on G sections I suspect there is very little water that gets in the legs. Probably mor

On my first Rohn 25 tower that I put up while in college, I had water get into a leg and actually busted outwardly. It left about an inch and a half rip looking seam. This occurred about 4 feet fro

What does the brain trust think about the idea of plugging the ID of tower legs slightly above the top of the concrete foundation and drilling a weep (drain) hole at the top of the plug. It would req
Why do people insist on putting the first section in concrete? If you read the K7NV analysis of guyed towers it is far better to use a pier pin base. Less stress on the tower and the problem of rust

Not everyone's requirements are the same. Rohn actually approves both methods as they sell base sections to bury in concrete. Yes, the tapered section is better but a whole lot more expensive. 73 NJ0
One of the problems with Rohn tower sections,, all of them-25G, 45G, and 55G, when the galvanizing was done at The plant,, galvanize would form inside the legs and create a "plug". Thus the water wou
Patrick: I recall a wise man once admonishing us, both here and in his book, "Up the Tower" (which my kids got me for Christmas and which I wish I would have bought before I constructed mine), " DO w

I guess I am glad that my rebar cage, by my request shipped in advance of the tower which hasn't shipped yet, has no hollow structure. It is all rebar where it contacts the concrete with rectangular
There are no weep holes in my Rohn 65G. John KK9A FYI, Rohn 65 with 4 bolt 5/8" thick flanges on each leg has one 1/4" weep hole on each leg, at both ends right next to the flange. The flanges are dr
I can't understand why so many hams build towers this way, especially a former AM BCB tower. The proper way to erect a guyed tower, particularly one more than about 50' tall, is to attach a flat base
Don, "proper" is a poor choice of words. Towers can be engineered either way, and there are pros and cons for each approach. How the tower is loaded with antennas sometimes affects the base choice as
All of the standard 65G guyed "catalog" packages come with a tapered base section for use with a pier pin. We have a 280 foot 65G at one of our FM clients' sites with a tapered base on a pin, and th
One thing I forgot to mention. With the pier-pin solution you normally don't have the problem of hollow-legged towers filling with water and the necessity of drilling a weep hole in the legs or maki
