- << Hi, I just installed the A3S with 40 m kit and got a problem. The SWR on 10 and 15 m is according specifications. The 40 m SWR is also about to be fine, i.e not bad than 1.8 on 7.0 - 7.1 MHz. The

- Looking for suggestions with a Cushcraft A3 problem. Up till this year it worked well. The swr was minimum at 14.1, 21.2, 28.4. Now it resonates at 14.5, 21.2, 28.0. Compared to a C3E on another towe

- Three things you might want to check: Crappy coax....water got in at the feedpoint. Bugs and/or water in one of the traps. Water is a notorious culprit in the A-3 traps. Rotate the boom 90 degrees on

- Absolutely!! I had the same problem with an A4S--just a few bugs and wet grass in a trap makes all the difference. After the clean-up, it was right on the money. By the way, you only have to clean th

- Tony, I worked on a friends A3 and checked the traps with a dip meter. One trap (can't remember which...doesn't matter) did not dip where it should. If you pull back the inner black cap you will find

- Tony, is the A3's Front-to-Back on 10 meters about the same as it was before the change in 20 meter VSWR (it is probably worth checking front-to-back on 15 and 20 as well)? If the F/B is unchanged, t
