What is the best way to run 450 ohm ladder line through a block/stucco wall, where the stucco has steel mesh behind it? There is no wood, vinyl, or window pane to use for access. I was thinking of a

With the help of my trusty ITT Blue Book, I can calculate the impedance of a balanced line passing through a grounded pipe. If your line is 450 ohms in free space with air dielectric, the balanced sh

the impedance your line is 450 shielded line has None of this matters, because to have a significant impact on line SWR the impedance bump has to be a significant fraction of a wavelength long. On T
