I'm looking for suggestions to lift mast, with antennas just enough to replace the rotator, which is a Ham III. Rotator is shelf mounted about 2 feet below the top thrust bearing. All ideas are appre

John, Use a lever (large screwdriver) to lift the mast a quarter to half inch. Then clamp the mast above head unit with either a muffler clamp, large hose clamp or perhaps a locking bolt in the Head
Put a clamp around the mast, tight against the thrust bearing to hold the weight, pull the rotor. If you need more clearance to slip the new rotor in, put a bottle or scissor jack under the mast at t
You really don't want to do that without bracing the mast with something like the braces Tim suggested. Years ago, I made something similar out of steel angle stock and U-bolts. BTW, although the DXE
John, As suggested a small piece of angle iron I mad mine out of aluminum angle and drilled it for numerious tower legs You only need to raise the mast ¼ to remove the rotor Wayne ,W3EA Sent from Mai
John - Next time install two bearings that provide both lateral and thrust support. And then install the mast so there is no weight on the rotor. Then you can easily remove and replace the rotor. 73,
I use a shaft collar on the mast just above the thrust bearing. That way there is no weight on the rotor. 73, Les VE3NNT Sent from my Bell Samsung device over Canada's largest network. -- Original me
Another guy just said the same thing you did, and I'm not sure that is universally a good idea. I expect Steve to eventually weigh in here with more authority on the subject, but from what I underst
Dave - My experience doesn't indicate that. My rotors, Yaesu G-1000DXA and Yaesu G-2800DXA, with no weight on them, have lasted for decades. Maybe other rotators are different. 73, Bob - W3YY Another
I am getting ready to install a new Alpha Spid rotator and called them with this question. The Alpha Spids do not require any vertical weight. They will run fine without it. I don't know of a rotator
My 2c, again In terms of number installed I think most rotators have angular contact ball bearings. HyGain, Yaesu, & prop pitch all are angular bearings, which are the only ball bearings designed for
with my 72 crankup, i have to extend the tower to get the rotor out ( orion2800). That puts it even higher than 23 feet ( the collapsed height of the tower). Sooo i tilt it over, extend enough to ge
I have had a fair amount of experience swapping rotators. At one point Hygain/MFJ had a pot problem; mine were wearing out in roughly a year. What I did was procure a 2nd "hot swap" rotator so that I
