Jim: If you ask around you may discover that lots of CATV hardline is
routinely tossed or sold at scrap prices ... especially the end-of-rolls.
You could either use 1.5:1 transformers (have a look at RadioWorks
http://www.radioworks.com/ or Amidon http://www.bytemark.com/amidon for
some options) or live with the relatively small mismatch loss (since you
gain so much in the loss area using hardline) ... the purists will correct
me ... I expect! :-) You may bury the hardline and avoid the potential
weather damage to the 600 ohm ladder line, forget worries about proximity
to metal, etc. All I.M.H.O. -- 73, DavidC AA1FA
