| #341: Ham tip: Safely using a coax switch to connect multiple rigs to a single antenna system
This video answers the question - "Can an antenna switch be used in reverse, to switch multiple radios into a single antenna system and, is it safe?" The answer is - YES, in most cases - as long as the switch grounds the unused inputs, which is usually the case. The video takes a look at the numbers, describes how much isolation is needed, and then shows how to measure the isolation using a NanoVNA, and finally shows the results using a couple of HF radios.
