4.3" Nano VNA-F V2 is a Great Value for HF/VHF/UHF Anrenna Field Work
A remarkable piece of engineering. Only 101 point data "samples" do limit performance (can miss signals entirely if scanning a very wide range); hence you have to understand how FFT's work to properly configure the device for certain measurements.
For the price, it's been an excellent value and performed well in testing thus far. Also functions very well as an HF/VHF/UHF antenna analyzer and has helped characterize some of my Ham radio antennas. It's small size make it a valuable tool for setting up and maintaining antenna systems during field days, etc.
The all-aluminum case is durable and protects the device very well against accidental drops, bench handling, etc. The on-off switch appears delicate, and I can see how it might be easily damaged in use. Thus far I've had no problems with that switch; but intend to treat it carefully (so I don't have to replace it). The foam-filled case allows extra room on the side for clearance to all of the switches (including the on-off switch). Carrying it in it's original packaging/shipping case seems more than adequate for providing reasonable protection. All in all, its been a very satisfying product and already helped solve some antenna performance problems.

A great time saver in RF work.
Helped me diagnose and fix a problem with a receiver in just minutes. Frequency and amplitude appear to still be very accurate. Fine control (10Hz increments in tuning and 1dB in amplitude) greatly helps in testing other RF components and devices. A great time saver in RF work.
