    I think Dave meant to say, "it can be low loss". Having a window line run in close proximity or touching metal objects, running window line on the ground, running window line through a structure, and of course window line getting wet. These are all scenarios where window line has potential to incur losses that just wouldn't happen with coax.

    When i first saw your videos, my first question was "why doesn't he just put the camera on a tripod ffs"
    But honestly, the slight movement is very satisfying. Especially at the opening, its absolutely perfect.
    I think you're the first channel who's ever done "shaky cam" in a good and pleasing way.

    Thanks for answering my question, Dave! It was concise enough to give me a place to start, yet left a lot of enjoyable rabbit holes to explore. Nice work!

    You did not even suggest window line with no Balun at the Antenna. An auto antenna tuner with memories would be able to match the antenna in no time. Even a manual tuner could be set repeatably to known settings very easily. With this setup the antenna would be able to operate on all bands ABOVE the fundamental frequency.

    Great stuff to know. Thanks Dave and 73

    Regarding the standing wave not actually being standing -- can you use superposition to describe the voltage along the line as the sum of a true standing wave and another wave? That would make the phrase "standing wave ratio" intuitive.

    Thanks, Dave. Enjoyed the video. 73, AC3HT

    I too have a QRP radio, the IC-705 and my first antenna provided to me is a G5RV 102' that came with window line as a feed line. I was told I would always need to run a tuner so I hook it up to my AH-705 which is connected to my radio via coax. Is this the appropriate way to run this antenna or do I need an additional balun? Also I sometimes struggle to find a tree tall enough to get the window line completely off the ground. I always make sure it doesn't coil and it runs perpendicular to the dipole wires but will touching the ground be badly detrimental? I haven't noticed an issue so far but how much worse is this setup than one where the center of the antenna is at an appropriate height?

    looking to replace my 150' of coax to my CB antenna with 450, and on both ends im going to use a coax balun 4:1 with a 1/4~ piece of 300 flatline which should bring it to 450. be good for monoband operation. not a ham so i don't have to worry about other bands for this one so i can ixnay the loss potential with using ferrite
