But now, 9 years later, i need to do something, because feel, that the system become degrades…
\nMy wishes to do: to change coaxial cables (both, TX and RX feeders), replace LNA, replace RX\/TX coaxial relay, to add one M218XXX yagi in vertical polarisation (and, respectively<\/span><\/span>, to add coaxial switch to change from V to H polarization for TX and RX). Not sure, that the last task is clever, but I will try. And it gave me a lot of additional work!!<\/p>\n

October 2016<\/em>. I started from digging trenches<\/span> for laying all<\/span> new cables underground: RFA 7\/8″-50 (TX feeder), 8DFB (RX feeder) and the control cable. Both coaxial are 28 meters long. Few day later I started to prepared new mast head box for all relays and LNA. Also assembling 1x 2M18XXX for vertical polarization. And preparation of all feeders, jumpers<\/span> and so on…<\/span><\/span><\/p>\n
