Hi, I am almost ready to build a Buried section base for a 25G tower. The hole is 2 x 2 ft and almost 3 ft deep...is it ok for a guyed tower?...it is almost half cubic yard...and about 2000 pounds of
I am almost ready to build a Buried section base for a 25G tower. How tall? What will be on it? The hole is 2 x 2 ft and almost 3 ft deep...is it ok for a guyed tower?...it is almost half cubic yard.

How about the center-pin base plate. More better to inspect for rust. I had issues, inside legs of buried section, never seen until it was taken down after 20 years. Sent from my iPhone How tall? Wha
I have 5 sections...so, it will be almost 50 ft high tower but one of the sections has problem in one leg at bottom, so, it is not a perfect triangle at bottom...for that reason i will use that secti
Jim, Thanks for the idea...Are those extra 22 or 23 ft of AWG 4 bare copper connected in some place of the buried section ???.. 73....Douglas, CO8DM "No creo que haya alguna emoción más intensa para
This is prevented by a layer of fairly large gravel at the bottom of the hole, so that it's underneath the tower legs. The water is coming down the tower legs from above, and the gravel allows for it
Thanks for the idea...Are those extra 22 or 23 ft of AWG 4 bare copper connected in some place of the buried section ???.. Just run it generally around the buried section. Concrete is fairly conducti

Don't forget, to provide proper drainage for the buried tower section set in concrete, such as about 6" of pea gravel or crushed rock.in the bottom of the hole. Mechanically, the base of a guyed towe
Jim, This is great...my qth is very small, so, i need optimize my ground system at the base. The base is about 12 ft from my shack and i have the radios connected to a single ground rod. This single
Thanks Jim and everyone with ideas. The buried section is painted...i think i must remove paint for better contact with concrete for good conductivity. 73....Douglas, CO8DM "No creo que haya alguna e
I am totally amazed at how concrete has weakened over the years. When I put up my 64' UNGUYED Heights tower in 1970, 4'x4'x4' was all that was required and that held a tribander and other antennas fo
1/6 of a yard of concrete for a freestanding tower? John KK9A I am totally amazed at how concrete has weakened over the years. For a 50' guyed tower, all I used was 30" square and 8" deep. Ken WA8JXM

The base for my LM470, is the first base where I've used rebar. The guyed 100' 45 G has a minimal (~1.5 sq yds) high strength base in hard clay. 3' in dia and a bit over 5'6" deep. I've had 50 and 60
