ANYSECU PS100 UV RF Vector Impedance ANT SWR Antenna Analyzer Meter Tester 140MHz - 2.7GHz N1201SA New Version

Works great. I make several kinds of antennas and this has proven to be a great investment. Easy to use after you look it up on Youtube. It is put out by Anysecu so don't count on getting the calibration package or any kind of instructions with it. You will have to order the calibration package and research how to use it. My experiences with Anysecu and their customer service has been useless.

Awesome testing device with enough features to properly set up an antenna. Could use improved button but works as is. No complaints on the price however. Seller pleasant to deal with and fast shipping.

The minute I unboxed this device I could not help but notice that the rotary switch had broken from poorly soldered connections. Virtually no written instructions. The multi-colored LED's were not from different gases in the semiconductors, but rather the colors were made possible by placing thin colored film in front of each light segment. The film moves about and gets caught sideways if your not careful. I never got to use the antenna analyzer because I could not get it into the proper mode because of the broken rotary switch. All-in-all, a very cheap and poorly made device. Not a recommended buy!

This is an excellent product. Don’t let the low price fool you, this antenna analyzer is a gem costing far less than other comparable products. Using it is intuitive. The didplay is clear and bright. It operates from 137.5 MHz thru 2.7 GHz a very wide range. Just the ticket to test and tune mobile and multi band antennas. Built in rechargablebbattery and included usb charger/cable completes the package. If you are in the field you can use any LiPo USB battery pack top it off for unlimited runtime.

Bought the unit after reading various reviews on the web. For the price it seemed to offer good accuracy when compared to lab equipment class units that cost thousands of dollars. I had SMA cables both 'normal' and RP and the gear to make them as needed. Important to have since the unit comes with no cables (other that for charging). Also no manual included, but fortunately they can be found online and there's also videos to refer to. The display is pretty good quality and easy enough to navigate. Would be nice if it had a keypad, but it is still usable without. Overall I'm very pleased with the performance and it can scan across many hundreds of megahertz is just seconds. Highly recommended if you are working with custom antennas, either HAM or ISM band transceivers. I had some so called (ebay junk) 915MHz antennas that performed poorly. Turns out that they are actually UHF antennas being deceptively sold as 915MHz units. The VNA immediately showed up their resonance point as per the attached picture. Put together a prototype Moxon antenna and then trimmed a little of the wires to bring them to resonance at the nominal 908MHz I'm using. See picture. The VNA also makes it easy to measure the impact of dielectric material in close proximity/contact with the antenna element and to adjust the antenna dimensions to compensate.

Awesome product. Great and accurate. Only reason for not giving 5 stars is due to not being supplied with necessary adapters for calibration and limited frequency range. Other than that? Nailed it!!!

This is a real game changer for me. The easy to use, color screen had me testing antennas right away. You can set a range and see where the SWR curve falls, and then adjust the frequency pointer as you adjust your antenna. Super easy and a great addition to the shack. I'm getting the HF version next.

Reactance (X) and impedance (Z) measurements are inaccurate below 2GHz and super inaccurate in higher frequencies. If you buy this VNA entirely as for SWR measurements, you're not in for a treat either. It's more or less impossible to get repeatable results. User calibration with open, short, 50ohm load results a completely botched profile. Even 50 Ohm load shows SWR of 2.2:1. There is no firmware update. Mine came with v0.83 and searching for a bug fix firmware yields no results. The brand on this, AAI is nowhere to be found. Not even a perfunctory Chinese retail website presence.
