    Bought to run non amplified loads, works fantastic for HF/VHF. Given the cost of good connectors is about $20 for a pair, and some cable to put between them and a nice chassis for each end, its not hard to price out and justify the overall price. Pros: Easy to install Little modification to pre-existing structures, maybe some screw holes or use double sided tape for mounting. Pretty good construction Works great for window use, my installation closes nice and easy, still seals well with it installed. (modern double pane vinyl) Cons: Not super heavy duty, not designed for high watt/amp use. Other thoughts: Not going to work with storm windows that you want to close. They are a good stop gap to get you on the air until you get a amp and run actual feed lines from your ham shack.

    Able to close window on cable and not lose heat. Very low loss of power. Small db loss when inserted.

    I was surprised by how well built this pass through was. It works as advertised. Great design with zero signal loss. I definitely would recommend this product!

    Works great! Using it for a scanner antenna and getting that antenna outside made a world of difference, I don’t see any notice loss with this product.

    Not exactly what the doctor ordered but the next best thing. Haven’t installed it yet but anticipate that it will work.

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! 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 in the wall or leaving a window/door open 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! Whether you route it through a sliding door or window, you can close the door or window securely without damaging the coax!
