Hi all Additionally to the interesting discussion around coax cables and double shielding I have another question. We have re-modelling / extension plans here at ZM4T. The new tower locations will re
Distortion requires a non-linear element in the signal path. Transmission lines are inherently linear. There IS the possibility of distortion in a ferrite core device used to transform impedance at e
I think Holger means crosstalk, rather than distortion. The critical issue will be whether the feedline crosstalk is greater than that from the antennas. There may be ways to estimate the feedline cr

Most 600 ohm open-line is not actually 600 ohms. I remember going through all the math of open line back in my Fields and Waves class in college. It needs spacing from other metallic objects in order
I wonder if twisting one clockwise and the next closest one counterclockwise would aid in any coupling minimization? They say open line is self shielding, but only to the extent described below. I re
Hi Holger We made extensive use of open wire feedlines at ZL6QH to connect antennas scattered over a couple of hundred acres of farmland. We often used the same poles to run up to 4 open wire feedlin
