Date: Mon, 2 Jun 1997 09:53:25 +200
As far as the guy line and the tower are concerned, yes. As far as the concrete and the stake are concerned, no. I cannot comment on the strength of a 4" water pipe. The tension in the guy lines will

Not quite. As an owner of both the 20M4 and the EF420, I can tell you there is a much more important consideration. The 20M4 is built like a tank, with probably a 3" boom in the middle. The Force 12

Sure. But the diameter is what determines wind load (in the absence of traps etc.), and it is a fact, based on the comparable antennas from both manufacturers that I own, that the Force 12 elements a

My experience is that the drill speed is the single most important issue. I wrote off several drill bits while drilling a mast, and my supply of four High Speed Steel bits didn't even get through the

It will snap off, taking you with it. I was faced with a similar situation a few weeks ago. It was one of the most unpleasant tasks I've had to perform on my tower. In my case, I had something like 5

Author: crb@nanoteq.com (Chris R. Burger)
Date: Fri, 4 Apr 1997 09:46:23 +200
I would think, intuitively and therefore probably incorrectly, that this notion would only apply to towers that are high relative to the length. In other words, I doubt if 50' of Rohn 55 would collap
