Times are getting harder and money is getting tighter.  Jobs are going overseas and my taxes are rising.  So i'm looking for ways to cut some corners and yet not have the station go down in operations.  In short, i'm looking to put into use Cable TV RG-6 coax as feedline to all the receivers from the switches and wherever else i can use it.  It's cheap for one thing, i've got a source of connectors and it's decently flexible.  I know it's 75 ohm stuff but i can't or haven't seen any difference in received levels nor what my ears could perceive since i started giving it a shot.  

What i'm looking for  is to have you experts that know about this stuff providing some legitimate feedback, shoot it down if you will.   Big thing is , why not?  It's a lot cheaper than RG-8, LDF4-50, LMR-400 etc.  And it's a lot easier to flex.  100 Ft for less than $15 from an auction house.  Cable TV guys will probably throw some extra connectors at you if you need them and the crimpers aren't hard to find either.  I've not had any problesms with reliability either.  Course it's all in the radio shack, but that's shouldn't be to big a concern.  Has any of you tried the same thing in the past or present?  What's your thoughts?

I'm not sure what the loss is at frequencies up to say 50 mc which is about as high as i would use it but typical Satellite systesm run 900Mc and up for down conversion frequencies to the the satellite receivers and use the same stuff.  I installed 100 ft plus runs with it in satellite antenna installations 25 years back.  That's another bit of history in itself so we won't go into that any further.

Bring on the information and i'll try to digest it.
