    I have three of these in use and I love them! Im using them on 40 through 10 meters and they have virtually no impact on SWR. Im using them as a temporary measure until the weather improves, but they have been working so well that I can see them being used in permanent installations.

    Expensive, but well made. No noticeable negative effect on SWR. Two more connections in the run, so has be some added signal loss, but I have no way to measure just how much. It certainly seems low enough that it does not matter to me; I didnt want to have to drill holes in the house walls, and this is a great solution.

    This though cable works great. Can actually close Windows on it.

    I was a bit leery at first, but after installing two of these, one at my house and one at anothers house, I looked at the feed on my analyzer, and I didnt see any detectable difference in loss or impedance bump with the feed-through, compared without it. People I tested with also noticed no difference.

    Absolutely garbage. Doesnt work at all, and its extremely flimsy.

    Works fine. No need to butcher your house.

    Meets all expectations

    Fairly expensive for what it is, but it works. As previous reviewers have noted, I dont think you would want to raise and lower a window on this device too frequently. I operate HF, and I dont see any negative SWR impact with this cable.

    Works as intended with little or no increase to SWR. I added some all-weather electrical tape to both sides of the flat strap to give it increased protection from the tight fit.

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!
