YouTube is your friend. :) ### ⭐⭐⭐⭐⭐ Great SWR for the money *by C***B on July 21, 2023* I have read a little on these devices over the past few months, and decided that for ham radio use, if they worked as well as people seemed to think, the small size, internal battery etc. would make it ideal for field antenna work. I really wasn't expecting that much at this price. However, it arrived in a nice looking box with fitted internal compartments for cables, connectors etc. My first quick play with it impressed me. I was suspicious about using a square-wave and using harmonics for the higher ranges, but if you forgive the reduced measurement range, that actually works pretty well. Not as well as my bench VNA, but that cost just a tiny bit more. The biggest potential problem is the number of sample points. Being fixed at 101 points is rather limiting for wide-band scans. That said, its not that usual outside of microwave use that wide bandwidth scans are used/useful. If you really need that, there is software available (free) for Windows and Mac to control the nanoVNA, and with the ability to split the range into some number (you decide - how long you want to wait) of segments, and scan each segment individually, merging the results into a single view. If I had to find fault, it would pretty much be with the external components: * A guitar pick is better than a finger on that little screen, but a stylus would be better. * There is only one 50ohm load, the proper calibration procedure requires two, although you *can* use just one. * The open and short calibration loads are identical once connected or an adapter fitted. Marking these 'O' and 'S' would be useful. * The box is too nice to toss away, but lacks space for additional adapters/connectors. All that said, I highly recommend this for anyone wanting a VNA for sub-microwave use and not requiring ultra-precision. If you have never used this sort of equipment before there is a somewhat steep learning curve, and most documentation is either at too high a level for a lot of people, and assuming lots of basic knowledge, or really too low level and created by people that are maybe not really grasping what they are doing. I expect that problem to resolve fairly quickly. As an antenna analyzer for ham radio use it blows most of those costing 10 or more times as much out of the water, and is useful for other things too (like tuning filters etc.).only using for SWR across multiple bands, but beats the price on buying multiple meters. ## Frequently Bought Together - SEESII Upgraded NanoVNA-H4 Vector Network Analyzer, Latest V4.3 10KHz-1.5GHz HF VHF UHF 4" Touch Screen VNA Antenna Analyzer Measures S Parameters,Voltage Standing Wave Ratio, Phase,Delay, Smith Chart - DHT Electronics Handheld Antenna Cable SMA Male to UHF SO-239 Female Connectors 6'' Pack of 2 for Amplifier - onelinkmore SMA to UHF RF Coaxial Extension Converter CB Connector kit SMA PL259 SO239 VHF Crimp Coax Adapter for Ham Radio Antenna Walkie Talkie Radio Pack of 4 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/189479846-seesii-upgraded-nanovna-h4-vector-network-analyzer-latest-v4-4](https://www.desertcart.in/products/189479846-seesii-upgraded-nanovna-h4-vector-network-analyzer-latest-v4-4) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-25*
