Today, the call TF4X has been issued for use at the TF4M station.
I have finished the Beverage antenna project for the time being.
I built 4 bi-directional Beverage antennas ranging from 170m to 380m long.
The antennas are connected into the radio shack via 5000 feet of RG-6 CATV cable entering via a patch panel and fed into a K9AY RAS8x2 matrix antenna switch which then feeds the 8 directions available into two transceivers.
The picture shows the center lines of the main lobe of each antenna direction. The lobes are quite broad especially on the lower frequencies, so I believe I have relatively good coverage.
One operating position is ready – position B which has the control unit for all antennas. Some work remains, dressing cables, installing computers and building brackets for Bandpass Filters etc.
