DIY Remote Antenna Switch Upgrades V 2.0 : Coax Mods & Power-Off Safety!

Join me, Jerry (KM4ZKB), as I upgrade my remote antenna switch! In this video, we replace long wires with RG316 coax for better RF performance, add a ground bus bar, and implement a power-off default to a dummy load or antenna for safety. Watch as I test insertion loss and SWR using a NanoVNA, then do real-world checks with antennas like a 40m delta loop, ZS6BKW, and Off-Center-Fed dipole. Perfect for ham radio enthusiasts looking to reduce signal loss and clean up their setup. If you missed the original build series, check the playlist in the cards or description below. Thanks for watching! Drop a like, subscribe, and comment: Should unused antennas be shorted to ground? Let's discuss!
