For some reason I did not scroll down far enough to read the second part of your answer. I'm sorry I missed it.
I redid my TVFool report using my exact address. It is in a rural area and not close to any city. There are tall trees all around my cottage. Here are the results :

You are correct I did mean CIII-DT and CHCH-DT.
I have replaced most of the 300 OHM twin lead with RG6 coax but will replace all as you suggested.
I'll check out where to buy a grounding block and attach it as you suggested.
Thanks again for you help and patience.
