> 3 dayIt’s expensive for what it is but it is the best thing I have found for feeding coax through a window. I added suction cups to it, 2 on each connection and it holds tight to the window and doesn’t beat the glass up in the wind.

> 3 dayAt best, this is a stop-gap device. Though I have a good experience with it across the VHF amateur band (1.2:1 SWR) I have issues with it on 70cm. The SWR at the low end of this band is ok but it rises sharply towards the top end to over 1.7:1. The stated insertion loss seems pretty accurate and it too rises shaarply on 70cm. My suspicion is that it was designed for primary use in Hf up through VHF but the manufacturer pushed its use on UHF to maximize sales. Unfortunately there arent many alternatives around (MFJ if your window has an opening up to 48). Otherwise the tape is quite flimsy and will, no doubt, turn brittle in UV light. At best, for my use, I can only rate it 3 stars...and thats pushing it.

> 3 dayWorks 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.

Greater than one weekWhen 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.
