Howdy, TowerTalkians -- Tnx to all for their input on the Orion and its mast clamping problems. While I've seen some bolt stretch that is probably a contributing factor to mast slippage, it seems tha
Howdy Steve et all; I think your proposed solution will work with any or all of the following mods: a) Use a locking compound between the inserts and the mast to mechanically bond them together. The
With one M2 2800p/Monstir combination and a second m2 2800p to have a large antenna I am very interested in this thread. However, I wonder if these solutions are a "band aid"? As mentioned by others
Hello Al, Valid questions all. The engineers at Orion would have to provide the estimated failure torques for the various parts of their rotator. Where do you want the weak link to be? I think most p
One more data point.... I had a CrMo mast with three monobanders on it at my previous QTH. I had no slippage in the Orion mast clamp. Antennas were all KLM (20M5, 15M6 and 10M6). Larry Burke WI5A Lim
Hmmm... so you mean kinda like the shear pin on my 5-hp trolling motor? I would much prefer a slip-clutch because once the shear pin goes on your antenna system, well it's pretty much a free-wheeling
G'day, at my all 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 Antenn
To add another thought to the long litany: Here in Texas, a number of folks have improved the gripping power of various rotator systems by adding a small section of tractor implement belt between the
Here is my 2 cents on a long and interesting thread... My original installation was 90' of 25G on a windy hilltop. 20' of 2" schedule 80 mast with 10' in the tower. Antennas 204BA, 4el Cushcraft 15 a
Guys-- But Dave later realized that the method he discussed was not the correct method and that the Cross-Flow method by Dick Weber, K5IU is the proper way to do it, as published in Communications Qu
