[TowerTalk] A3S

[Glenn Pritchard]

Mosley, show me any time a Mosley’s traps have failed! You can’t . Oh I put more than 500 watts on RTTY and no issue. Cushcraft has smaller traps and that’s okay as you never know about them ..

After taking it down, testing all the traps, and putting it back up, it seems even worse on that band, consistently 10-12 dB below the other tribander 20 feet above it. SWR is above 2:1 near the center of the band, well over 3:1 at 21.0. It works fine on 10 and 20. I've heard that the A3S has often had problems on 15. I've replaced, rebuilt, retuned, and tested all the 15m traps. (The MFJ replacement traps needed a lot of work.) There are no nearby metal guy wires or antennas. Has anyone seen similar problems and solved them? I'm about ready to scrap this antenna.
