Oh, OK. It is also weak and has the same problem of the curvature of the earth. Hold off on Tin Lee until you make a test with the UVSJ and the Juice preamp. If you do need a filter for a separate antenna just for ABC, it would then be for real channel 15.
If you don't get a hint of either ABC with your C4, a UVSJ and the Juice preamp as a test, then it would be a gamble whether an upgrade to a separate antenna just for ABC with more gain and a custom filter would do any better. I don't want to give you false hope and waste your money.
