for 20th April, when most of the antennas will be assembled and
mounting on Tower one. Layout of antennas on tower 1 are shown on picture left..

Antennas are designed by Deni, T93M (tnx Deni) and built by YT6A each
antenna has CMC balun and some of antenna stacks will be switch able

antenna combination, depending on propagation and local static noise
