I like and use T2X and Ham M rotators. For the first 10 years turning my 3 each 4 element long boom stacked array I had lots of problems with the T2X. Sticky brake, broken ring gear. All problems wen

If the director is about .2 wavelength from the driven element the signal should be S9 + approximately 2 dB. de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA ZX0A VU7RG TX5C A52PP OK, this may be a dumb
You will get slightly more gain with a reflector. Tuning a vertical array is easy. Install a sample vertical antenna about 100 feet away, decouple both antennas from their feed lines and connect your
That is not my experience. When I designed and built vertical dipole arrays for 20, 17, 15, 12 & 10m I found the reflector arrangement always provided better forward gain. de Paul, W8AEF ZF2JI/ZF2TA
As N7RT and I have found, there are horizontal days and there are vertical days. Install both antennas and you are covered both ways. de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA ZX0A VU7RG TX5C A52
That is true but remember you can have one or the other - not both. de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA ZX0A VU7RG TX5C A52PP I suppose a similar scheme would work if you wanted to optimize
When I built the SVDA antennas for Clipperton/Midway/Kanton I used the following procedure: Erect a parasitic element with a length close to a reflector for the desired frequency, just a little longe
I had a similar experience when the drive chain broke on a friends HDX-589. Incredibly poor design to put the weakest link (the chain) in the drive line after the worm drive. It really makes me appre

The multiplier used to be 300%. If a man makes $15 per hour, his time is/was charged out at $45 per hour. And that was a long time ago. de Paul, W8AEF ZF2JI/ZF2TA 8Q7AA FO8DX/FO0PLA XZ0A VU7RG/VU3PYM
I just removed a 25G tower and a Ham IV rotator was mounted inside it and no braces were cut. Maybe you are working with a T2X rotator? de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA XZ0A VU7RG/VU3PYM
You are correct and that is why I was able to remove the Ham IV without any problems. The missing cross braces are between the upper two horizontal bars. de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA
At one time I used a CR-18 roof tower. I had two antennas on it, 15m and 10m 3 elment yagis. I did guy it 4 ways. No problems in the 4 years I used it. de Paul, W8AEF ZF2JI/ZF2TA FO8DX/FO8PLA 8Q7AA X
I prefer that my antennas and towers lose their shiney. They get gray and dingy and just fade into the background and the neighbors cannot see them. de Paul, W8AEF Thanks for the suggestions. FYI the

You will probably not be able to get parts for your Yaesu rotator when it fails. de Paul, W8AEF One of the many puzzles remaining is to decide on the rotor. __________________________________________
