...a cheap $3 75ohm to 300ohm converter...been a good while since I played around with this sort of thing, but I thought the conversion used to be from a 300 ohm twin lead antenna line to a 75 ohm coax input line - I'd better brush up before I try hooking up my old attic antenna to the HDTV TV....

You're correct. It's a 300 ohm twin lead to a 75 ohm coaxial input. I stated it incorrectly.
