144 Mhz array 4x2M18XXX

All this job had been done in August – September,  2007.

But now, 9 years later, i need to do something, because feel, that the system become degrades…
My 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, 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!!

October 2016. I started from digging trenches for laying all 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 and so on…


December 2016. Winter become, but not so much snow yet and not so cold (-2 degrees at the day and -7 at the night). Additional antenna on the frame and mast head box on the place.
