Author: crb@nanoteq.com (Chris R. Burger)
Date: Thu, 11 Dec 1997 18:37:43 +200
I saw a reference earlier on the Reflector that reminded me of something I'd wondered about--often. I've noticed that come-alongs and other hoisting gear are often rated differently for pulling and l

A few weeks ago, I posted a request from ZS6AWK for help with a rotator problem. His meter was fluctuating during rotation, so that he could not see the actual position of the antenna before it stabi

That's EXACTLY what I did with my 402BA (2 el Shorty Forty) above a 205BA (5 el 20 short boom) for several years, without a problem. I moved the same tower to the new station, this time with a C3 tri

Two points: 1. Any idea what would have happened under these conditions if the mast was not pinned? I would think that the kind of torque that could cause this much play would have allowed the mast t

My point is simply: Why does someone who is prepared to repeatedly climb the tower to re-align the beam (because it was not pinned), not climb the tower to do routine maintenance to avoid the kind of

This is a very personal decision. I thought I would just point out the facts, so that you can take the best decision for yourself. 1. The Alpha has a very low risk of plastering you all over the road
