Assembled and tested.

This transformer requires a feed line choke to isolate the coax feed line from the antenna.


Grounding at the lug next to the SO239 connector is recommended ! Long wires tend to collect electrostatic charges (usually when the weather is stormy) which can produce ESD (electrostatic discharge) at the end of your cable and damage your equipment.
