Window/door feed-thru jumper

The CTC-50M jumper allows you to get the antenna coax into the radio room without drilling holes in the wall or leaving a window/door open.
The center core of the flat wire coax is "copper-clad steel" chosen for its strength and resistance to metal fatigue.  The film is made of ALPET (aluminum/PET plastic) also to resist damage due to material fatigue.
25k gold plated connectors are supplied with screws to attach the connectors securely to the wall/window frame.

Close the window and screen freely without damaging the coax!
