New 4-Square Switchbox de K8UR.
After designing the ComTek 4-Square Switchbox almost 20 years ago, I've
designed a new improved model.
This one is controllable via the Internet, switches in 8 directions and has
a nulling function for receive.
You can still use your same 4 verticals or K8UR vertical array.
Coming this Spring. Listen for me on 20&80M.
