The Inner Workings
I have received a number of inquires as to what resides within the coaxial junction box for my 10-60 meter portable antenna.
So here is a look at the inner workings, with the wiring routed between the SO-239 connector and the antenna connections.
The wire used is 12 gage tinned buss wire that I also use for building the inductance coils used in the construction of the majority of my HF antennas.
All fasteners used in building this coaxial junction box are stainless steel or brass.
You may be asking why I have 2 external connecting terminals for the ground side and the center conductor of the antenna.
This allows me to install a shunt-coil between the two points on the outside of the housing if required.
The bottom terminal attached to the ground side of the SO-239 coax connector, is also used for attaching the tuned ground radials for the antenna.
In case you were wondering where you can purchase junction-boxes like this one for your antenna building projects, you will find them in the electrical isle at Home Depot or any other hardware outlet that sells electrical hardware.
