At moderate heights (70-80') and assuming mechanical concerns are not a factor, I vote for the tribander on top. If you do HFTA for the antennas at around 80 feet, you will find that for usual arriva

I really don't understand why it is a subject so hard to understand. A self-supporting tower will have certain forces on its legs from a wind pressure. Supplied with guy wires the forces from the win

Hi Rick, I have used the falling derrick system on towers up to 60ft. I am not familiar with the tipping point phenomenon so you might elaborate on that a bit. 73, Gerald K5GW In a message dated 10/1

FYI... My 60ft R25 uses the falling derrick method. W3GM had four 100 footers that used this method. W3EA presently has several and N2TK uses this method for his R45 tower. 73, Stew K3ND Hi Rick, I h

Doug, I have to correct one of your statements: Any metal structure, in general, is stronger in tension than in compression. This doesn't change your point, though. Hans - N2JFS I have a hard time, l

You are right, Doug When it comes to structures like towers you have to take in consideration the buckling effect. Just an extreme example; a long steel wire cable has no strength in compression but

What would work if you bury it deep enough. I would believe 8 feet of strap buried 4 feet down should be equal to an 8 foot rod pushed down 8 feet. Any comments? I do think it is less work to push th

John, Wouldn't the soil condition have the same effect on a rod pushed in and a buried strap? Hans - N2JFS That depends on your soil conditions. Some of us have shale, rock and/or hard clay making it
