50 ohm aluminum jacketed hardline used to be common, I have had 7/8 inch air
filled and currently have 7/8 inch foam 50 ohm, besides a few hundred feet
of 3/4 inch 75 ohm CATV stuff. I prefer to call this stuff hardline and the
corrugated stuff Heliax to differentiate when I talk about it. Yes, Heliax
is a brand but I have never seen smooth aluminum jacketed cable branded as
Heliax, only the ribbed stuff.
Finding the proper connectors for the smooth aluminum jacketed stuff is
getting very hard, you pretty much have to deal with surplus and used. I
have about 165 feet of Cablewave FXA 78-50 I have been looking for
connectors for.

Are you sure you have 50 ohm coax? The CATV distribution rems are 75 ohm.
Cable Z is the starting point for your research.
Some of the surplus around 0.5" od is SFX500 (bare), IF it is 50 ohm.
The connectors are readily available new, check ebay for N & 7/16 DIN.
UHF are really rare.
Power rating for SFX500 is 5KW to 30MHz and that's the baby size of what you
have.
