	Unfortunately, some cable companies seem to go out of their
way to make things hard.  Since you seem to be saying that they transmit
at 500 ohms, then you will either need their box, or a simple transformer
to convert from 500 to either 300 or 75 ohms. Sorry, but the only
transformers I know of for certain go from 75 to 300 and vice versa.

					Hope You find one that works!
