Earlier this year I saw a cable & wire dealer advertising flat 50-ohm coaxial cable jumpers with UHF connectors on either end. The jumpers purportedly were flat enough to fit under or around doors and windows and were for transmitting.

I've tried Google searches and several amateur equipment dealers without any success,

Does anybody have a lead on "flat" coaxial jumpers?


Thanks & 73!

All I have seen are RG6 for satellite/cable TV.

An easy solution is to cut a 2X4 (or 1X4 or ???) the width of the window and put bulkhead connectors in it. Then close the window down onto it and put a pin at the top of the window to prevent it from opening from the outside (a screw works well).

A flattened coax cable? I see a huge Impedance change with that. Cant be 50 Ohm.

Thanks to everybody who responded to my question about a flat coax jumper.

I finally found it. It's the COMET CTC-50 WINDOW GAP JUMPER. The jumper is rated at 100 watts HF, dropping to 10 watts at 900 - 1296 MHz FM. I'll be in contact with NCG for more information, especially dimensions and bending/compression limitations.

I may finally get on HF without having to bore through the exterior walls and insulation!
