AW07A antenna analyzer is a compact battery powered RF impedance analyzer. It can test the SWR status of your antenna, measure the impedance and reactance component and help you to solve antenna problems. Yes, I know they get drifty in UHF and VHF but they do work. Price includes shipping in the USA. Condition is 9 out of 10. I use PayPal for payment . Thanks for looking and 73s.
