This VNA covers 1 MHz to 3 GHz and the software offers a number of options for typical one and two port VNA measurements for checking antennas, filters, cable loss, amplifiers, etc. The TDR function ...

I’ve managed to successfully tune a 15.56MHz NFC antenna without a VNA although if I’d seen that article I might have gone for a miniVNA instead.

Even with a VNA it’s not silent, you can hear the signal being injected with your radio nearby. I routinely do this when tuning my magnetic loop antenna because it’s extremely narrowband.

I had a chance to review a new 1-port vector network analyzer (VNA) from Copper Mountain Technologies (CMT). Their model R60 VNA was packaged with a couple dozen test antennas from PulseLarsen ...

Fortunately, dual-purpose analyzers that combine spectrum analysis and VNA are available now, which are designed with a mix ...

Testing Antennas with a Network Analyzer Jan 6, 2013 9:00 AM, By Jeremy Ruck, PE No doubt one of the most revolutionary tools for the RF side of broadcasting was the advent of the network analyzer. ..

You will also need a source and a receiver, which could be a separate signal generator and spectrum analyzer, or a vector network analyzer. Sources such as eBay can be used to locate older used ...
