Comet Window Feed-Thru Jumpers are flexible, 50 ohm, flat feedline assemblies with SO-239 UHF female connectors at each end. They are used for routing RF through a window frame without drilling holes for the coax cable or connectors.
These window-gap jumpers are almost 16 in. long and are made from copper-clad steel and PET plastic to allow for a low power transfer of RF with a nominal loss of only 0.5 dB up to 500 MHz, and they are useable up to 1300 MHz!
When drilling through the wall is forbidden, or if there is no way to make a sufficient hole for your coaxial cable, then a Comet Window Feed-Thru Jumper may be the problem solver that you need! Here are the specs that will help you decide if one of these handy flat cable assemblies is right for you:
* Frequency Range: DC-1300 MHz
* Connectors: SO-239
* Impedance: 50 Ohm
* Length: 15.75 inches
* Max Power: HF 100W PEP, VHF: 60W FM, UHF 40W FM, 900 MHz–1.3 * GHz: 10W FM
* SWR: Less than 1.3:1 below 500 MHz, Less than 1.5:1 above 500 MHz
* Loss: DC-500 MHz = 0.5 dB, 500-900 MHz = 1.3 dB, 900-1300 MHz = 1.8 dB
