Hi guys, A friend of mine offer me a HAM III just used for 3 years only, and I got a HAM IV not so good condition, in fact, I donīt know if it's working effectively. And I wonder if YAESU G-800DXA or
Ham IV is a beefier rotor for bigger antennas. What are you going to spin with the rotor? Ham IV is rated for 15 sqft windload. Ham III is 12.5 sqft. All depends on how big your antennas are. -- Mike
Although the "Ham" series may be rated at 12.5 and 15 for the Ham 3 and Ham 4, in the real world it ain't so. Having used the 4 series and the Tailtwister for years, experience prevents me from putti
The "Ham series" of rotators are good, well designed rotators. they just aren't meant for large antennas and particularly antennas near their ratings in his winds. Other than that they work great and
Bill, et. al., I agree that the Ham series rotors will have problems with big antennas, however, if you are on a budget and you know about the modes of failure, you can make them work. Two of the rul
Having used to old Ham series on antennas as large as full size KLM 5L 20 meter and 6 L 15 meter antennas (42 foot booms) I'd add two points: Don't use the rotator when the wind is strong. If necessa
Hi Roger, et. al., When the wind really blows, I hold the brake down and let the antenna rotate by turning the motor to the direction it wishes to be. I then release the brake lever so the brake is r
I have stayed out of this discussion because things mechanical are not my strong suit, and I have had my share of rotor problems lately. At any rate, several months ago I had a discussion with Craig,
I think that is basically what I've been saying. But as to detail the gears in the Ham series of rotators as well as some of the Yaesu rotators I've seen are very thin, stamped steel. They uses a ser
