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....!!!
