[CTSARA] Question

[Jon Perelstein]

I'm not familiar with RG-5X so I don't know how long it supposedly lasts in
open air environments nor what it's impedance is.

One thing to check is the impedance.  With a G5RV, it's possible that the
coax is something other than 50 ohms in order to get proper matching to the
ladder line and antenna.  If it's not 50 ohm, then you kind of don't want
to replace it with LMR-400 because of the impedance mismatch it would
create.

As I understand it, LMR-400 is heavier (weight) than the typical RG-8x or
RG-58.  Depending on what length run you have, it may be too heavy for a
free-standing dipole in which the antenna is not supported in the center.

Check first about what the coax is and its impedance.
