Well I have managed to get two more channels, 3 to go. Little cold windy today so I'm not going to mess with it until tomorrow. We even had a little bit of light sleet this morning.

This sounds like the next issue and would explain why that black box made it worse at my Grandmother's house assuming it's an amp.

Be aware that amps and pre-amps will actually cause you to lower your Noise Margin. No matter how much gain an amp or pre-amp claims, it will actually reduce your Noise Margin by the amount listed as the Noise Figure (NF) in its specs.

Amplifiers can also overload the receiver if the broadcast signal is strong.

I use a pre-amp on my system to make up for a long cable run and a splitter. A few channels will occasionally drop out if the amp is not used...no problems with the amp on.
