Product Information

If anyone else that has received a NanoVNA-H4 would try the above and let me know the results I'd appreciate it. Mauris eleifend, quam a vulputate dictum, massa quam dapibus leo, eget vulputate orci purus ut lorem. The biggest advantage of the 4" display is the graphics are not as compressed and the larger fonts can be laid out normally so that the screen is more legible (See the attached photos for comparison). GHz vector network analyser designed to measure reflection and transmission coefficients of equipment without the need for a large analyser.

Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item. Reviews of equipment capable of CB/Freeband operation or not FCC Certified/Type Accepted may be removed.In the time since my first review, I have built a 4el VHF/7el UHF satellite beam and completed a VHF installation in the SUV. band is better than 40dB of dynamics;The metal shield is designed to reduce the external interference and improve the measurement accuracy.

I've started looking into NanoVNA so I can understand a bit more about antenna performance and design. This Antenna Analyzer is provides outstanding vector network measurement capabilities and perfect for evaluating antenna resonance and SWR. Took a gamble with this (bit more expensive than direct from China, but got it next day, no customs, etc), and as you can see from the photo's it looks as genuine as they come. Supplied with: 1 NanoVNA-H or Nanovna-H4, with calibration kit, 1 50Ω SMA dummy load, 1 SMA open circuit, 1 SMA short circuit, 1 USB Type-C power cable, 2 SMA Male RG316 15cm cables, 1 SMA female - SMA female adapter.If someone can describe menu changes or point to an image for printed NanoVNA-H4 Menu Structure Map, I will create and updated map for https://groups. the only caveat is that these analyzers may be hard to read in bright sunlight, so keep that in mind for field operations. eHam's Product Reviews are intended to provide an opportunity to share an opinion, positive or negative, of a commercially available ham radio-related product or service. Like I posted earlier, don't consider this a stamp of approval as I only use a very small subset of the firmware's features but still this 1.

Note: other parts of the script were changed as appropriate (or at least to my understanding) for 320x480 resolution. A separate charge pump to power the mixer and tantalum capacitors were added to reduce the power supply noise.I simply suggest that anyone in the market for one of these devices, join the (different) NanoVNA-Groups. eHam considers soliciting and/or rewarding favorable reviews by manufacturers/dealers as unethical and unwelcome. The notes below take you through the setup procedure for checking SWR and aerial resonance and tuned circuits and quartz crystal frequencies. You need high quality leads and adapters, the slightest movement will cause erratic readings with all but the best leads. It's reasonable to assume the OCXO will do a bit of retracing its previous lifecycle until it settles.
