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!

HELP -- FLAT 50-OHM COAXIAL JUMPER
Flat Cable
About the only flat or near flat cable I have seen is the mini-stuff. I think it is mostly used for internal wiring and I don't know if they make adapters to use UHF connectors or not. Also I'm not sure how much power it would handle, but some of those small Teflon cable can handle a lot more power than you would think. Is this for HF? How much power are you talking? Just the electrical characteristics of impedance would make it pretty difficult I would think. I remember about 40 years ago there was a 72 ohm twin lead made by Belden. It was pretty flat, but overall probably not much thinner than RG58, but if I remember right I believe it was good for a KW.
FOUND IT!
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!
