Too bad they are out of production!  Time owned: more than 12 months
I have one now and have had others in the past. The only thing I don't like about them is the lack of a "stop" on the motor. They are very reliable if installed properly and kept under the winload limit.

Works for me!  Time owned: more than 12 months
Hello all. I put this used HD-73 up back in late 2005. I got it on 70' of Rohn 25 with a 3 element 17 meter monobander with 2" od 19' boom made from a couple of DB-224 masts. I also have a 6 meter monobander on it with a 6' boom. I got this stacked on a 9' steel mast. Only problem so far is lightening took out a motor winding and some components inside the control box. I had some spare parts, so I re-built. She is back up and still going strong. I have a HAM 3 and a T2X that needs fixing and I may do that, but why hurry, the HD-73 is working great.

Excellent for the price  Time owned: more than 12 months
I've owned two of these, got both of them at separate times for about $125 each, including the control box.

They never failed to work, are a better design than a lot of other rotators, and I've never had any problems with these unlike I have with HyGain rotators.

Excellent Medium Duty Rotator!  Time owned: more than 12 months
I've had 2 to 3 of these up on towers at one time or another and I've only had to pull 1 rotor and that was only due to a lightning hit knocking out the bearing pot. (I only pulled it as I had to redo everything up there anyway...)It was on that 100 ft. tower for well over 10 years. Presently I have two in use and they just keep on ticking.
I keep a couple extra in storage for that "just in case" situation. The HD73 is underrated in capacity because I have more than 10 sqft of antennas on them and I don't use a thrust bearing. This was one one the best values I've ever found in amateur radio!

can't break'em  Time owned: more than 12 months
4 in the air for 13 years, no problems yet! Wish you could still get them.

Keeps on working and working  Time owned: more than 12 months
I picked up a used one on eBay a couple of years ago and it is mounted OUTSIDE the top of a small tower turning a 2 element 5 band Delta Loop quad antenna. It's been through 60-70+ mph wind gusts and exposed to subfreezing and 116 F degree summer temps and hasn't even flinched.

I had one years ago and same solid results. Only thing that kills these is Mother Nature and a solid lightning strike.

Finally broke!  Time owned: more than 12 months
After years of reliable service turning an A3S at heights anywhere from 20 to 50 foot in the air this rotator finally broke. We had 90 MPH winds come through this spring and the last 60 degrees +/- of due south will not work any longer. Am told by rotor repair place that this is due to gear or drive breaking due to being torqued. Rain or shine, cold or hot it just worked and worked for me. Think I got my money worth

Too light and no brake  Time owned: more than 12 months
I have gone through three of these in five years and rebuilt two of them twice as well. They are rated for 10 square feet, and that's really more than it can handle. I had a TH6DXX (10.7 sq. ft.)with a thrust bearing. The rotor turned the beam just fine, but came apart in 45 mph winds. Granted, I had 10.7 sq. ft. of antenna on it, (7% over rated wind load) but it should have been able to handle this at 45 mph. The lack of a brake is a key issue. Fine for small, 3 to 5 element beams, but that's it.

Great for Small to Medium Beams  Time owned: more than 12 months
I have turned a Mosley MP-33-N WARC (29 pound beam with 15 ft turning radius) with this rotor for almost 13 years. It is accurate, relatively fast, holds up well in winds (up to 60 mph or so in western WA), and is relatively inexpensive. During that time it has never missed a beat. Mine is mounted on a telescoping TV mast right above roof peak and no thrust bearing. I see it's rated to 10 sq. ft. and that's plenty for me. My only other experience is with light weight rotors (e.g. Alliance U-100)for small 6m beams. Norm's Rotor Service ( bought out Alliance and is the source of rebuilt and new HD-73s.
