[TowerTalk] Ferrite beads for LDF4-50?

[Chuck Dietz]

I have been thinking about this myself and I wonder if the connector
between the hardline and the rotor loop might have more loss than the
difference between the hardline and LMR400 ultra flex cable. In other
words, maybe just run LMR400 and not have a connector in line.
I have not done the math, but I think it would depend upon the total length
of the cable. Mine will go from the stackmatch to the bottom of the tower
where it will connect to 7/8” hardline.
