HF Yagi antenna maintenance 2

 A big thanks to SV5/SV2MAC Kostas for his excellent work on my A3S traps (cleaning and retune) New plastic covers from RayCap for traps and check with NanoVNA. Next days will reassemble the Yagi and hook it up again on tower.

HF Yagi antenna maintenance....

 My HF yagi antenna (Cushcraft A3S) is down for meintenance after many years on roof. Trap covers gone by the wind and SWR readings at 10m and 15m moves higher than center frequencies. My good friend Nikos SV5KKN, helps on tower work and guywires change. During antenna disassembly a trap spacer broke. Looking on Internet I found a 3D printer file for it. Vaggelis SV5FRV offer me a quick printing. Now the traps and spare parts are ready to leave for Kalymnos where SV5/SV5MAC Kostas will clean and retune them. Thanks for Ham Spirit and help guys....!!!
