Simple QRP projects, 10m, 6m, WSPR beaconing, LF/MF, sub-9kHz, nanowaves and other random stuff
Hello,I have a similar unit (http://www.sonigate.com/pt/product/show_details/29932/Rotor-Antenas-ate-45Kg-Peso-Vertical-Completo-com-Comando-sem-Travao) for some years and still works OK, but, it is not placed outside, for outside use and looking from my unit construction I suspect it would not last long (maybe 3/4 years unless frequent maintenance is done) on an harsh or salty climate although it has rubber seal on the rotating part.Has plenty of strength for small antennas like TV broadcast ones.Hope it helps
Roger,I use one very similar to that one for my folded VK2ABQ up 6 meters on a mast. No problems so far and the dial seems to stay properly synchronized. The antenna (see my blog) is definitely larger than recommended length-wise, but it's pretty light. 73,TI2/NA7U
Looks like a bargain to me, for the price its worth giving it a go!
Looks like a Chinese AR-303 rotor.The control panel has got a motor. It moves the bearing pointer in the console's display. So expect some unpleasant noise in your shack from the console when turning your antenna.Take a look here for a modification and pictures of the entrails: http://www.qslnet.de/member/dl5za/And consult youtube:http://www.youtube.com/results?search_query=AR-303
Go for it. The best setup is both a steerable directional antenna and a separate omni-directional antenna. You listen for calls on the omni, then QSO with the directional antenna. This reduces QRM for both you and the rest of the community, and you can use far less power. Plus, looking at the direction of an incoming signal can often tell you something about the mode of propagation. David WB4ONA

At the old QTH (we moved a few years ago) I used my Homebase-10 antenna for 10m. As we are approaching the Es season when 10m springs to l...
