New QO-100 antenna and feed....

 Last weekend I decide to upgrade my QO-100 antenna system. My good friend SV5SKE Euripidis gave me a 1.5m diameter prime focus dish (brand new). Also PE1LWT a year before send me an POTY feed so the gear it was around and ready to be assembled. The only thing that have to carry was the waterproof of feed point and BullsEye LNB preparation. My good friend Vangelis SV5FRV make the 3D printing of POTY parts.Thanks guys...   The construction takes all Suturday long and went just fine. Few final adjustments needed and Im count on the help of my good friend SV5KJO Giorgos as an Satellite expert. With my very fast adjastments, my signal on QO-100 improves and I see signals as 59+ on downlink...

 

Here is the results on air....

 

 

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....!!!
