- mikewarot 4y agoA VNA is a vector network analyzer, a device which can make fairly precise measurements of radio frequency electronics networks. These devices used to sell for $10,000 and up, recently someone figured out how to make a reasonably good one for hobby use, and they can be had for $100 or less. You can use them to test antennas, tune filters, find the frequency of crystals, and other things.
