| One more data point.... I had a CrMo mast with three monobanders on it
| previous QTH. I had no slippage in the Orion mast clamp. Antennas were
| KLM (20M5, 15M6 and 10M6).
Maybe they are properly torque balanced. There was quite a thread on this
subject in January 2005. The David Leeson spreadsheets derived from his
book "Physical Design of Yagi Antennas" provide a method whereby mast
torque and appropriate compensation can be calculated/designed. Seems
more sense to me that trying to make stronger and stronger more grippy
clamps and bust gears.
The book is a good read too.
