    Great product

    Modern windows are tight with no room in the slides. This would not allow my window to close with this either in the side or at the bottom. Great idea, but it didnt work for me.

    When I ordered this, I could find no mention that these feed-through jumpers worked with newer horizontal sliding vinyl double-pane windows. Being very energy efficient, I was concerned our 3 year old windows would seal too tightly for this jumper to work. But I can now tell you, it worked for our windows and very well. I purchased two of these jumpers, one for HF and the other for 2M/440. The cables are one on top of the other and Ive seen no interference between the two signals. This jumper solved my problem of not wanting to drill through our stucco walls. Now I can run both radios (HF & Dual-Band) with the window tightly closed.

    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.

    Still feel its too a little expensive for what it is, but it works well.

    for 50 bucks you get a window passthrough with minimal power loss and you do not have to drill holes in your walls. Update after one year the cable is separating. It still works though

    This is intended as a 50 ohm flat window sash pass-through for coaxial cable used by amateur radio operators or others who need to get the coax from outside to inside without drilling a hole in wall or window sash for coax. It is quite flat with overall thickness of about 1/16 inch so it can use the space between the window sash and frame. It is well constructed with sealed joints on the ribbon conductor.

    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.

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!
