    Works great! Window closes completely. I use one for 2 meters and another for HF.

    Windows in our leased house are the swing-out variety, so the usual slide-window pass-throughs dont fit. I eventually bought three of these, one for HF, one for VHF and one for UHF. Insertion loss is better than I expected, and SWR is acceptable in all three bands. The only downside is that being as thin as they are theyre not the sturdiest. Best used in locations where you can put them in and then dont open/close the windows a lot.

    It does what it is supposed to do, but the price is a bit high. I use this to provide a connection between my patio and my back yard via the patio door. So far, i am only using QRP power levels. Since I install and remove it when I am done, my only concern is how well it will hold up over the long term. So far, it appears to be well built and thus, so far, worth the price.

    Great for feeding antenna around a glass sliding door and still close the door ok. Had one for few years and slamming the door on it so this was a replacement.

    I bought one of those non-descript cell phone signal boosters to help me with the reception in my basement office. This jumper, while a bit pricey (I only paid around $70 for my booster), does the job just fine. I tested the booster with and without the passthrough jumper, and it has no detectable effect on the signal. I had to get a set of UHF/PL-259 Male to N Female Connectors to hook it up, and everything works well. I am in the early stages of planning my ham radio shack, so Ill be buying more of these. My wife takes a dim view of drilling holes in the wall.

    If you follow the directions and treat it like a cable you just spent > $50 on, youll be fine. Being a Chinese copy of the Diamond part doesnt seem to make a difference quality-wise but I only bought one.

    Did not expect to have 1.01 SWR with a 25 foot LMR 400 cable on 2m and 70cm. This saves me anther hole in my wall during the winter, this is a temp setup until its nice enough to drill.

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!
