Any input on a Hy-Gain AR-500 Auto Rotator I'm thinking of using it with a MFJ-1890 moxon antenna mounted on a mast. Is this rotor strong enough or do I need to spent the extra dollars and go with something like a Yaesu G-450A
Compare the specs for both and then you decide if one is 'better' than the other.

I've never had one so can't say anything about it from experience. I have had a rotor or two, one not being a very 'large' one. It would turn the antenna, but the wind also did some unwanted turning!
Just as a very general 'rule of thumb', meaning it's a terrible way of judging a rotor, it it's sort of 'square'ish in shape, and not very heavy, then don't expect much ability to turn and -keep the wind from turning- the @#$ antenna. That unwanted turning is a function of the braking system used. There's a huge amount of force being applied to any antenna by the wind, and keeping the thing 'still' is a major part of a rotor's job. I didn't look at prices (scared too!), but I would expect a 'good' rotor to be expensive. That 'Hy-Gain AR-500 Auto Rotor' just isn't a heavy-duty rotor at all, sorry...

Incoming Region Produces X3 Solar Flare |
May 15, 2024 @ 14:55 UTC |
Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
