That'll really depend on a number of factors.
What frequency are you using?
What kind of cable is involved?
Here's a very slick calculator from www.timesmicrowave.com. Almost all of
the coax I use is LMR cable from them.
I don't know if Andrew or anyone else has a similar mechanism.
Hope that helps!
