So if 9913 and LMR-400 are discouraged - due to maintenance
concerns - then it is either Davis RF Bury-Flex or some form
of hardline on 6m and 2/440?

HF is much more tolerant of line-losses so I will use my
older RG-8U and RG-8x coax there.

Still have not decided how I will get the 450 Ohm slotted
line for my HF dipole into the steel house ... hmmm.
