    Works great. Better than drilling a hole through the wall. Ive had it about a year and it has been a very good product.

    $60 for this?? I graduated to big power, and even my transceivers running barefoot will not work well with this. I ran a Heathkit HW101, Yeasu FT857D, FT1200DX, FT897, all had more loss using this than using a piece of square tube closed into a window with SO259/239 connectors, and N connectors, as well as ladder line, hard line and window line balanced cables. If you are renting, this is a very viable option, but $60!?!

    This was exactly what I wanted. So far it lives up to its description. It seems sturdy. It was overpriced for what it is, but when youre the only game in town you have that latitude. I wish they made something similar for running my ground line.

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

    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.

    We have double hung wood windows. I did not want a panel in the window frame nor do I want to drill holes through our incredibly expensive siding. I know this is a tradeoff but one I have to make. I got two of these as I hope to try out at least two different antennas. I like that they are long enough to also fit under the outside window screen.

    Great Solution to a Common problem, but it seems too high priced for what it is. I guess when youre the only one that makes these thats what happens. I would Suggest selling for $35......maybe more would be sold. Overall, Im happy with the quality and functionality of the product.

    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.

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!
