Rugged and accurate  Time owned: more than 12 months
I've used the AT-500 for work for 7 years now. It compares favorably to a network analyzer and a service monitor for accuracy and of course is small and very portable. The one and only issue I have with it is it goes nuts when being used in an RF-dense environment, display jumps all over. Of course it's hard to find an antenna analyzer that doesn't. I have to resort to a service monitor and a return loss hybrid to get any reasonable results when there are a few other transmitters around.

Very sensitive to ESD  Time owned: more than 12 months
I think this device is more useful for test and tuning of VHF/UHF antennas than for HF, because it is very sensitive to ESD. There are often problems with damage of the input RF detector at the moment of connection to the stationary HF antenna. Also, it is only possible to get VSWR graph, but there is no opportunity to check active and/or reactive resistance component.

Very handy  Time owned: more than 12 months
My unit is the AT-100 which covers only 2 to 136 MHz but in all other respects is the same as the AT-500. Super excellent for field day and mobile HF antenna checks. The batteries are a major hassle, six AA NiCd cells required and you can't use alkaline. The external 12VDC input can't be used without the batteries being fitted. The input connector is easily swapped with others and uses the same intermediate coupling as the Greenpar Between Series Adapter kit I also use. Overall extremely useful.

Accurate instrument  Time owned: more than 12 months
I've been using the Bird AT-500 for about 3 years and find it to be a valuable tool. Very compact with good battery life. The processor is slower than I would like, but I am used to it and have grown to live with this annoyance. Accuracy is excellent, as compared to an IFR COM-120B and an Aeroflex 3920, both radio test sets. The unit is supplied with an N female connector but others can be purchased from Bird or Pomona. The AT-500 has a somewhat ESD sensitive front end, so users should short the centre pin of the antenna feedline before attaching. Fit and finish is not classic Bird (the unit rattles a bit!) so I was somewhat surprised at this. I also own two similar units, and they all rattle. But despite these limitations, I could not work without my AT-500.
