Are they acceptable for avionics use?

I wouldn't use them for anything - let alone on an airplane.

My advice would be to get some RG-142 coax cable and the correct
connectors for it. Then invest in (or borrow) the correct crimpers,
and learn how to properly install the connectors. Then do the job in
your plane. You won't be sorry - the RF cables in my plane have been
working fine since about 1979.
