Great tuner

Time owned: more than 12 months

I bought this tuner back in the early 90's for my trap 80-10 dipole. I could always tune it for 1.5:1 or less, and marked the settings down for future use. It gave me no problems, and I liked the cross needle meter. It does only 80 thru 10, and not 160, but my old TS530sp liked it. Large case, and High Q. No loose fittings on mine at all. Great tuner for me.

Works well for me

I bought this used quite a few years ago and it continues to serve me well. I've used it with a 55' inverted-V low above a one-story townhome roof, and now with a 140' inverted-V up 38 feet-- both fed with ladder-line. I have had no trouble tuning the former from 40 - 10 meters, and the latter from 80 - 10 meters. There just have been no issues with it. I was previously using an MFJ-948 for which I had to build a much beefier internal balun to make it work properly (and not heat up) with my 55-footer; the AEA experienced no such issues. It's just too bad it's not designed to work on 160 meters.

Picked up at a bring and buy as new in box thought i had made a good find but its the worst tuner i have ever used it won`t tune anything right, another person below said his won`t tune anything it must be wired wrong i would say its down to poor components and build another £35 down the drain.

Nice Tuner

Have been using one of these about a year, no problems. Tunes my Cobra antenna and the G5RV with no problems. I like the detents on the 18 position inductor selectors, gives you almost as many choices as a roller inductor. The MFJ-949 has only 12 inductor tuning positions, so the AT-300 has 50% more postitions. The lighted 2 1/2" wide swr dual needle meter is easy to read. Ran it at up to 350 watts with no problems. The antenns connectors on the rear have large insulators for a balanced line. With tuners running close to the $200 mark if you can find one of these used it is a good buy.

waste of money

Time owned: 3 to 6 months

I bought this tuner second hand and it was in mint condition. I dont know what is up with it. It has a very poor tuning range. In fact. it has no luck tuning a 80 full wave loop or helping on a 5 band vertical. I have not been able to find a wiring diagram. I suspect it must be wired up wrong internally as it doesnt tune any antennas I am using. This tuner has 2 switched coils and one variable capacitor. I would love to have this tuner work... anyone else have any luck? Mine is destined for the next swap and shop.
