September GARA Meeting – Inexpensive VNAs in Action
A number of club members have recently purchased a vector network analyzer called “NanoVNA” off of eBay and we will be demonstrating how it works and measuring various antennas to show how well they’re tuned. These devices can measure many different electrical parameters including complex impedance, reflected power and SWR to show you the performance of your antenna or antenna system. If you’d like to see how your antenna stacks up, bring it along! This will be a fun and educational demonstration of an inexpensive piece of measurement equipment at work.
Update: here is the link to the NanoVNA on eBay if you are interested in purchasing one. Many of us have been successful offering $41.00 for the device, so you might try a lower offer than the standard price: https://www.ebay.com/itm/NanoVNA-Vector-Network-Analyzer-HF-VHF-UHF-Antenna-2-8-TFT-Screen-50KHz-900MHz/333311602300

I regret not being able to make the meeting but I did get a NanoVNA for $32. This is an awesome piece of equipment- thanks for sharing! W4VU
