Hi Bob,
I've been working on getting my 1983 Long-EZ back to flying
condition. It has RG-58 coax and BNC's with a soldered center
conductor and the screw together compression fitting for the
exterior shielding. There are also splices done with BNC's to
change radios over the years. There have been issues with the
transponder and the com transmitter (copper foil antenna in the
winglet) over the years.

How does the wire look? Still pliable? Are
the connectors on tight (i.e. do not rotate
if lightly twisted). RG-58 is a legacy materials
product with vulnerabilities and performance
issues that have improved with RG-400 et. als.
But it is not a pariah wire to be purged.

RG-58 and replace it with RG-400 and new crimp connectors?
|
If the installed wire is in good shape, the runs
are usually so short in a light aircraft as to
offer little improvement on performance for
making a change. It's a matter for your
personal sense of craftsmanship. If you can
get at the RG-58 runs, the time and cost of
replacing them is small in the grand scheme
of things . . . but there are no technical
imperatives for doing it.
| Quote: | If this is worth doing, how do I deal with the coax coming out of
the BNC's on the radio trays?
|
Those connectors can be opened, de-soldered and
refurbished with new wire . . . assuming you have
the tools and talents.
| Quote: | Can the RG-400 be spliced to the RG-59 just beyond the the tray BNC's?
|
Yes.
