Jon, you just made yourself another product. If the expensive ones are
that sloppily made, then there definitely is a market for such an item.
Just one problem. RG178 coax is not 75 ohms, but 50 according to every
goggle hit on the first page.
Searching for 75 ohm ultra-miniature coax, it looks like Canare has that
market sewed up, they have an already bundled product in 3, 4, or 5
individual cables which are nominally .102" per signal, so the end product
is .362" in diameter for a 5 run cable. Each coax in it is color coded,
but the outer jacket comes only in black. Looks like the minimum order
might be 100 meters.
Also, Hitachi Cable in Manchester has a smaller one yet, the 40252, which
may be suitable as individual runs you would have to self bundle to get 5.
But Canare has all the tools for their product if you use their connectors
too.
