RigExpert AA-55 ZOOM Antenna Analyler .06 - 55MHz

This is the best of the 3 analyzers that I own. I got this because it covers the frequencies I was most interested in. I was impressed by the instructions. Very easy to read and complete. The display is large and bright, the buttons function well and even the case fits well. Overall, great value and worth every penny! Suits my antenna tuning and cable testing needs perfectly.

Just another fantastic analyzer. Price is right. Does practically everything you need.

This is the third antenna analyzer (one just for 2m/440, one a very functional but complicated VNA-H and this one for HF) I've added to my shack, and it's by far the easiest to use. Replaceable batteries, a usb cable and bluetooth PC connections, an easy to read meter, Antscope2 software, and a very good form factor that makes it easy to hold and use. If I had any complaint it would be that the strap for the case is incorrectly assembled, but...since I'm using a foam lined case instead of the included one..that won't affect me much. It's baptism by fire will be installing a new 2 meter repeater and antennas later this season...I'll update this review after that field test.

If your a ham ànd like me do all your own repairs or anntenna builds your really going to need this great meter. Most anntenna work i do i can easily keep the swr at 1:0 or lower..just a awesome tool.

I bought this to tune antennas to resonance and to adjust the matching for lowest SWR. It has a SWR versus frequency plotting feature that makes this easy. It also reads out all of the relevant data. It can display Smith charts. It plots return loss, reflectance coefficient, impedance and phase, resistance and reactance. It can also simulate a time domain reflectance plot. It can determine cable impedance and group velocity. It can even measure resistance, capacitance and inductance. The calibration feature allows the analyzer to compensate for cable characteristics. In short it does everything that a vector impedance analyzer should do. It seems to be reasonably accurate. An antenna analyzer doesn't need to be very accurate just to tune antenna. It is light and compact. It is simple to use. It comes with a good manual. It has a USB interface that can be used for updating the firmware. The USB interface will power the instrument, bypassing the battery. There is a download for a PC that works with the USB interface. The analyzer can be fully controlled over the USB. The download software is capable of more detailed plots than the are possible on the analyzers screen. The instrument is powered by 2 AA batteries, either alkaline, nickel cadmium, or nickel metal hydride. Lithium cells have too high voltage. Rechargeable batteries must be charged outside the instrument. It has no charging capability. The color display is a bit difficult to see in sunlight. This is a great instrument, especially for the price. It is manufactured in Ukraine.

Unit appeared to read high compared to 3 MFJ testers I have so I did calibration on tester and then it fell in line with other testers I have. Unit is easy to use if you read manual first. When I checked my truck antenna it read a 2 SWR, after calibrating it showed a 1.19 SWR reading . little large but not like MFJ testers. After every 3-5 days I have to recalibrate tester or it reads higher than other testers I have a 2 SWR where others read a 1.15 SWR.I recalibrate and it reads close to MFJ and other testers I have.

I wish this was the Bluetooth version. But I didn't know till after I got it. Other than that it's a stellar product. Works perfectly

As a new ham, I was able to quickly find SWR and resonance frequency when tuning and installing a 20/40m dipole. Highly recommended.
