How do you know if an antenna you bought online is a bad idea or is good? The NanoVNA is a low-cost instrument that is indispensable for any amateur radio enthusiast, and even for those who build their own antennas! It can measure, in addition to these, filters, amplifiers and various types of inductance, allowing you to use it to analyze chokes (baluns). Oh, and one more thing... thanks to everyone for the 500 subscribers!! ???? -------------------------------------------------- ????
