Lucky you!  I moved and lost my source.

You can use a coax matching section at the antenna if they are 
monobanders, this works fine and you need a flexible loop anyway.  I ran 
7/8" CATV hardline 350' to a 2m yagi with a very good match.  The 
calculations are in most every handbook.  The transmitter mismatch 
should not be a problem.  A no tune semiconductor linear may foldback 
with 75 ohms but it would be a finicky one. Any PI network linear should 
work fine.

This hardline also makes superb low loss broadband dipoles, using the 
shield as the element and the (usually copperweld) center conductor as 
the messenger wire.

The compression plumbing fittings are the cheapest way to adapt to PL's.
