[CQ-Contest] Hardline adapter 7/8" to 1/2"?

[Raymond Benny]

Does anyone know if there is an adapter made for Andrews 7/8" hardline to
Andrews 1/2" hardline? How about the same using coax DIN connectors? I have
never used them but they get good reviews.

I have several smaller runs of Andrews 7/8" hardline and a large spool of
Andrews 1/2" harline and would like to connect them together for (2) 300ft
runs..

Any other thoughts or comments?
