I'm not familiar with the Rohn HDBX 48 ft tower, but the only advantage that I ever saw to having your rotor located at the bottom of the tower was just the fact that you didn't need to climb the tow

I almost agree with all that but I do think better of using Braded instead of solid since it is the surface or skin that carries everything and that being the case braded has a lot more surface or sk

This has been my solution and it has worked very well for the past years. For each tube of your antenna take 2 pieces of PVC pipe that is just a little undersized for your antenna tube size. Each pie

Why Use Forms? A lot of people ask that question but I can tell you why I use them when I pour a tower base. The Earth sucks the moisture from the concrete and causes it to have weak spots becase it

While 2 days is good setting time for a pour that is only 4 - 6 inches and everyone says at least 2 days, because of the extreme thickness of the tower base I always allow a full week for it to dry.

One final suggestion - Make your tower base a few inches higher than the surrounding earth. I always make my pours 4 inches higher. This will allow water to run off the base during a rain instead of

It's too bad that you don't have the bottom section. I understand the weight issue with placing it there for the pour. We have 2 iron horses that are placed outside the base hole and use 2 heavy angl

Steam pipe has lots of good uses but I don't think you will find it any good for your plans. The weight of the stuff is about one and a half times the weight of a normal pipe the same size. You said
