VNA does exactly what i needed it to do, ive actually gotten an xtra small ant. turned on the air QSO from ky to cali.

Though the learning curve is a bit steep, this is a great tool for testing and setting up ham radio antennas.A good value as it is considerably less expensive than most of the antenna analyzers on the market.

This is a very important tool works very well

This is for connecting to an antenna. If you transmit through this with a radio you'll fry it.Hook an antenna with whatever adapter you need and this will analyze the swr and find the resonant frequency.

This works great but it does take time to learn all the steps done in the correct order to calibrate and get it to work correctly

if you want to actually see what the SWR curve actually looks like, this is the best product vs an SWR/Watt Meter if your transmitter is working. Also, you can find shorts in transmission lines, too.As the saying goes, in the land of the blind, the one eyed man is king!

This thing works great.

Dang it is small for old eyes. I have only used it in my 'shack' so cannot comment about outside visibility. I have a Diamond 5 band trap antenna and wanted to tweak the radials a tad. There is a menu print out in the box but nothing else. I had already downloaded a couple of how to documents. Both documents commented that there are several versions of the Nano so your screen may look slightly different,I played with it a couple of hours before connecting my antenna (remember to get the adapters if using the vhf 259 type connectors). It was intimidating at first but after running through a SWR set up a couple of times, it started to make sense.I had three bands to set up so used the same trace and changed the frequency range. You have to recalibrate when changing frequency so really not a big deal. You can save four traces.The recalibration is simple. Takes maybe two minutes but if you don't do it, a doubt your readings will be accurate.To me, it is well worth the cost.
