I ordered this NANOVNA for use in my EMCOMM bag for my 2m, 70cm, and 1.25M band radios.This comes with NO instructions, but diligent searching on Youtube will get you the basics to get started. This is not a quick and fast tool. You have to study how a nanovna works. This is not a tool you just pick up and intuitively use.I am at the very basic level of use, so I cannot judge the complete functionality.The display is bright and crisp. The touchscreen is relatively responsive with a good stylus. There is a good selection of adapters and there is a calibration set with the unit. I’m at the level of learning how to use the calibration set.I am going to give this a 5 star rating based upon the initial functionality and potential use. This looks like it will be a great addition to the EMCOMM bag. Thank you to SDRGEEK for offering it.

This is not a meter for the faint of heart who are looking for a way to measure the SWR on their CB antenna or those who want a simple way to check their base station antennas. Yes, it will do that...and much more. However if all you are looking for are simple standing wave readings there are SWR meters available in this price range that are very simple to use. I also purchased an ealier version of this device a couple of years ago which is still available but has a smaller screen. While the screen on this H4 version is not huge the size increase does make a noticable improvement to it in my opinion. Also, the PC software has continued ro improve as well and the H4 paired with a laptop PC is quite pleasant to operate.If you are technically inclined, a radio enthusiast, one who understands and builds antennas and feedlines, then this is definitely a tool you will thoroughly enjoy. Other than a block diagram chart which displays the H4 menu choices there are no instructions provided with this product. Although that is a disappointment it is not a deal breaker as there are a number of online manuals that are easily downloadable as PDF's. Most are 60-80 pages long and detail the various features and measurements that are available with the VNA. There is a learning curve but with the help of a good manual it's not too daunting. Additionally, there is software available to connect this VNA to your computer where you can easily see and print out the changes that occur as you modify the devices you are testing. At this price point it is obviously not 'lab grade' equipment but it's pretty decent and to explain all it's capabilities would be quite a task. If you are on the fence I'd suggest that you download one of the manuals and check it out. It's well worth it's price if you are inclined to really delve into the world of RF experimentation.

This VNA is an excellent tool for analyzing and designing antennas for ham radio and GMRS use. Very useful for checking antennas and coax cables. I primarily use it for checking SWR, but it has so many more capabilities. I use it just about every time I make any kind of a change at all to an antenna or coax cable. I learned to do that after wrecking a couple of inexpensive handheld radios shortly after I got into ham radio as a hobby. This nanoVNA really lets you see how your antenna system is performing, and how safe it is for your radio. The nanoVNA packs a huge amount of capability into a very small and inexpensive piece of test gear.This particular VNA works very well, has a nice bright display and a good touchscreen, and it does everything that it should, but there is a pretty steep learning curve associated with using this device if you have not used one before. The device comes with a single 8-1/2 x 11 sheet of instructions that show nothing but the structure of the many menus. The instructions on how to use this device are spread across the internet in the form of technical papers, videos, and websites. I have found that it is actually kind of fun learning how to use this piece of gear, and along the way you can't help but learn more about antenna theory.If you are into radios and antennas, this is pretty much a must-have piece of gear.

I have an implanted 125KHz RFID chip which I use for various things. Because of its design and size it is not easy to couple with using regular loop type air-core coils, and a few times I have come pretty close to tearing during writing.The solution is to make a winding over a ferrite rod -- if done right this will end up with the field strongest at either end of the rod where I can press it into the skin for a directional signal.This is the perfect piece of gear to have for this, since I was able to (with the help of a certain AI friend named Claude) construct the coil, test it, and modify until ideal.I got some mystery ferrite rods and enamel wire, wound up an antenna, and hooked it to the VNA and had Claude walk me through calibrating the device and then tested it. Got the inductance and reactance and Q factor, and we figured out a good value for a tuning capacitor which got put in the circuit, then gave it a go. Worked perfectly.I have to admit this thing is really intimidating. I think RF engineering is basically magic and looking at the menu the first time makes me feel like a kindergartner walking into a college class and asked to do calculus, but a good guide got me through it.If you need the data this provides, I have to say it is totally worth it.

The VNA works but the screen is only 2.8" and really small. It hard to use the touchscreen without a stylus. Also it only has 4 memory slots so saving multiple calibrations is troublesome. The function seems fine and accurate.

It works. I immediately connected it to my PC with the supplied cable to make it far easier to use. I did not like the design that slaps the PC card to a screen and leaves the case exposed to the elements and the user's fingers.

Works well but no instructions or website information in the box. After playing around with all the little buttons and touch screen I found a web address to a GitHub page.
