This switching unit will be used to simulate HF antennas in the frequency range 1.5 … 30 MHz. It can simulate two 3-channel Watson-Watt antennas.


The switching unit is housed in a 2 U 19“ subrack with very good RF shielding and consists of the following sub-assemblies:

-    2- and 3-way power dividers
-    solid-state switches SPDT
-    attenuators
-    processor board
-    LAN interface

All the necessary signal, power supply and earthing connections are provided at the rear.
The mains switch is located on the front panel.


The unit is controlled via a LAN interface.

Special features

The unit is constructed using a modular approach utilising 19” plug-in sub-assemblies which enable ease of installation and maintenance.
