My NanoVna SAA-2N VNA gives a top-notch performance, rivaling other analyzers at a fraction of the price. The 4-inch LCD screen is easy on the eyes. The only minus I've found is that you must manually save the calibration data for each frequency band, which is not a biggy if you work mainly in one or a portion of a band. Recalling calibration data is as simple as pressing a button on the touch screen, and speaking of which, the touch sensitivity is perfect. I opted for the N-type connectors with better longevity than (tiny) SMA. SMA-to-N-type adapters are easy to use. The unit is in a strong metal housing and has an easy-to-use zipper-style protective storage/carry case. Highly recommended for ham radio work and experimentation.

I bought the n-type version of this analyser to set up antennas on 144mhz 432mhz and 1.2ghz. Firstly it was an easy choice as it covers these frequencies. It is fairly robust, It is easy to use portable (if you need to get up a roof or tower) as it contains a chargeable battery. The screen is not that bright in sunlight but I was still able to see the swr traces with no problem. It provides many functions via a menu using a touchscreen pen. For instance it will add markers to traces to highlight the lowest swr point so that you can calculate changes that might be required. You can define a freq range easily and it will provide a quick sweep. In terms of accuracy, the swr readouts on my radio match the readings given by the VNA. Overall I am very happy with this purchase. It will be useful for many future measurements.

The analyser works great. I use it for tuning and checking my antennas. After you set it up with the calibration it is easy to see exactly how your antenna looks. I would have given this a higher rating, but my first unit was missing one of the calibration lugs. I was sent a second unit and had the same problem. The supplier worked to make sure I got the need part. It took about a month, but I have the part and the unit works great.

I replaced one of the smaller NanoVNAs with this. I considered those $50 VNAs to be useless junk. I was very pleasantly surprised at the quality and functionality of this one.The connectors and cables are lab grade and very high quality. I had this up and running RL and IL tests in under 5 minutes (including the initial calibrations). It's not a $50,000 network analyzer, but its performance really isn't that far off for 99% of what I do... and for the money?Yes, this could be used for antenna work up on the tower, but modern antenna analyzers (like those made by RigExpert for example) are much more user-friendly than a VNA for antenna work. This is intended to be a bench top analyzer and it performs that function very well.The S11 TX port is essentially an analyzer that does pretty much the same functions as a hand-held antenna analyzer, but the addition of the receive port brings in a new dimension: this can also do RF insertion loss measurements. This was a much needed function on my test bench and allows me to do filter work.Don't waste your money on the $50 VNAs. Buy this one.

The SAA2-N VNA is a ground-up remake (but not of the original NanoVNA team) of the ever-popular NanoVNA featuring female N connectors for both ports (adapted from internal SMA connectors), a larger and easier to read screen built inside a metal case, the male N connector standards, two short N M-M jumpers, a nice hard carrying case with enough room to store the VNA and all accessories, and a higher usable frequency of 3GHz. It also delivers a test kit consisting of a 7x7 row pin header with provisions for six PC mount SMA connectors (included). Careful examination of the PCB will reveal the interconnection pattern between all of the lands. I have yet to discover a use that I would have for the test PCB, but those who are into experimenting with different passive components and filters made from them will find the accessory handy. The N jumpers appear to be of decent quality, and the standards are built well.Unfortunately, like the original NanoVNA kits available, there is no way to enter cal kit polynomial correction factors without using the SAA-2N connected to a PC or Android and supporting software. This makes the NanoVNA all but useless for lab-grade high-precision use, with one exception. This is that the hardware, although capable of enough sensitivity, precision and dynamic range to display complex impedance changes on the order of milli units around the center of a Smith chart, can only give the operator relative differences between different devices under test (DUT) - not an absolutely accurate value; this inability to enter the cal-kit factors mean the actual impedance and reactance will be different than what the SAA-2N reads. I verified this offset using my HP 8753D and the 85032B calibration kit. Using a polar chart at .01 units per division, both phase and magnitude offset from 50-J-0 were apparent when measuring an identical load. This barely factors into a concern though considering that the SAA-2N is aimed squarely at the amateur market, and any error in measurement will be well within most amateur's acceptance range.Keeping with the NanoVNA spirit, this device will go well in the tool kit one can take up a tower to check an antenna or feedline. The metal case, although contributing to less isolation and more noise from internally reflected signals, is a welcome change from the typical plastic construction of other pocket-sized VNAs.Like the original NanoVNA, this one has a strong online user support base, and it was easy to find the forums that the designer frequents.For sure, this VNA has found a home in my test kit.

I purchased this device after reading an article on making filters and testing them with a VNA, I decided I needed one for my home lab. The last time I used a VNA was at work using a commercial very expensive table top unit from a major manufacturer of test equipment. I wanted one that went to 3 GHz since I like to build VHF and UHF ham radio equipment. The use of N-connectors lead me to this one since SMA connectors are fragile. It also has a metal case. Some of the VNAs do not have a case or have a plastic case. I went to the website in the included instruction sheet and downloaded the software for my iMAC and my Windows laptop. The software works great on both computers. The website also has detailed instruction manuals for the computer software and the software on the VNA. It can be used without an attached computer but is easier to use from a computer. Other vendors of VNAs include a set of attenuators with the VNA. This would be a worthwhile extra. There are three cables in the box. 2 are N-N male and one is N-SMA male. It is not clear from the description that the N-SMA is included, since it is part of the test kit. I am glad I spent the extra money to get the 3 GHz bandwidth and the N connectors. By the way, all of these VNAs are copies of an open source VNA project. I have had the VNA for about a week, so I can't comment on long term reliability. But the entire kit including the VNA seems well constructed.
