Hello all, Anyone have info on the magnetic switches which are used in the Orion rotators? I am using one now with a prop pitch gearbox and looking for spares. It's about 5/16 inch in dia, with a whi
Hello all, Since this thread has turned into quality of the gearbox as much as the pot replacement, thought I would share my experiences. Almost exactly 10 years ago, I purchased a PST-71D for use wi
Hi Jim, It is mechanically strong. This model, at least. If there was good shaft sealing and no water intrusion, I think it would be fine. Pots don't often fail and I have already figured out a fix f
Hello all, This base coil provides the correct amount of inductance to tune the antenna for a low SWR on 75/80. There is no 'magic bullet' to how much this would be. It all depends on each installati
Hello all, As I recall, in a 50 ohm system, 1500 watts is about 400 volts and about 6 amps. Could someone give me an approximation of what I could expect at 2:1 and 3:1 SWR? Or, direct me to a formul
Exactly what I was looking for, Steve. I should have mentioned that I was looking for a max number. Would hate to have the device conduct while running the 'full boogie'. 73 de Steve, NR4M Firstly yo
Hello all, I'm good at some things and not so much, at others and I have problems thinking 'outside of the box', so looking for ideas. Have a multi mult here in central VA, which seems to work well.
Hello all, Thanks for all the ideas. Best i can say now, is that it looks like it will be a long, drawn out PITA. W4TV: Re the pre-selectors in the Flex. They were 'engaged' (turned on; enabled...) F
Hello all, My guess is it's some sort of Mosley antenna. Those cast clamps are exactly like the ones I've seen on the Mosley's I've dealt with. And, those plastic element mounting blocks are very typ
Don, Finally glad to see that someone else is a bit more 'clued in' on tensioning guys using a Loos gauge. So often in the past, I've seen people recommend them, and others, go on and on about how gr
Hello all, Over the last few years, I have added four square arrays for 40 meters and 80 meters, and both work really outstanding. Recently, I added a third one for 20 meters and am having a difficul
Hello Peter, I just don't remember it that way. I guess I'm just getting old. Another told me that I needed to remove the coaxes and short the box end of each coax. I'll kick it's butt tomorrow. 73 d
Hello Charlie. I don't know why. I've done it both ways with each installation working quite well. And it may be something like, depending upon the phasing, unequal currents in the radial wires. if t

Hell all, I think I agree with Wes. How else do you show a prospective customer how it is built and quality of the parts used. Since it's 'built to order', there would not be one in stock to open up
Don W7WLL I find hot dipped galvanized is superior to stainless steel. Too often the stainless is 'one-time-use' stuff because of galling. I have never had a galvanized U-bolt fail in any way. I get
Hello all, I have one of those really large, really heavy Telex/Hygain rotators from a military tower system. It is 12" x 15" x 22" long and probably weighs 120 pounds, or so. Internally there is a A
Peter, It appears that there may have been 'something' on the inside of one of the panels, but nothing now. Steve 73 Peter, DJ7WW Hello all, I have one of those really large, really heavy Telex/Hygai
Joe, A couple of years ago, I built 4 Moxon's for 40, two for me and two for a buddy (actually, he help quite a bit) and could not be happier The boom is 21 1/2 feet as I recall and I know the elemen
Hello Gary, Good luck on finding something. Years ago, I was not happy with my choices. I just can not see paying ~$15 for a SS U-bolt and 'part-the-way-around' saddle. Don't know the alloy of the SS
