Hey guys, trying to finalize my setup, installer put in my HR10-250 but he didnt know how to work the signal strength meter for my OTA antenna. I can pickup all of my locals in HD except CBS (which is VHF as opposed to all others which are UHF). I live in Dyer, IN which is just outside of Chicago, I bought what I thought (according to antennaweb) was overkill, the thing is huge. Should I call and have a (hopefully) more qualified installer come out to fine tune it? I cant seem to focus on all of the good things that work well, I just keep dwelling on that one channel I dont have :nono2: . The installer I had claims that CBS is next to impossible to pickup in my area. Thank you very much. Note that antenna is unobstructed and has a clear view far as I can see. Also a side question, should the ground block be in my basement and not attached to anything? The guy has one of the wires that are attached to the coax attached to the ground block, but nothing goes from the ground block to ground??
