  On that basis, see if you can get some 75 ohm "hardline" from
  your local cable company - they are pulling it all out in favor of
  fiber optic cable and throwing it away unless the local hams
  ask for it.  We have several hams here who use that to go up
  70-100 foot towers and get out very well despite the apparent
  mismatch.
