The bottom line: this flat, flexible feed-thru jumper is for radio operators and installers who cannot drill a hole and need a secure, low-loss connection point with UHF female (SO-239) connectors at each end. It delivers a practical workaround for temporary or semi-permanent antenna runs while protecting the seal of the opening.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlat, flexible feedline:\u003c\/strong\u003e The low-profile design lets a window or sliding door close fully while keeping the cable and connectors safely inside the frame.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSO-239 UHF female connectors:\u003c\/strong\u003e Standard UHF female ends simplify hookup to existing CB or two-way radio equipment without adapter fuss.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e50 ohm impedance:\u003c\/strong\u003e Matches common radio systems to minimize reflections and maintain signal integrity for typical HF\/VHF use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow loss up to 500 MHz:\u003c\/strong\u003e Nominal loss of about 0.5 dB up to 500 MHz keeps signal attenuation low for most mobile and base station applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUseable to 1300 MHz:\u003c\/strong\u003e The construction supports operation beyond VHF into higher frequencies when occasional higher-band use is required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1 Year Manufacturer Warranty:\u003c\/strong\u003e Comes with a one year warranty that provides basic manufacturer coverage for defects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Comet CTC-50M is aimed at CB and two-way radio users, portable antenna installers, and anyone needing a temporary or reversible feed through a window without damaging the building.
