I used to have a Concord antenna on my 2000 Country Coach. After getting damaged by a tree limb in a campground I replaced the Concord head with a Jack. It worked fine until I could no longer get power to the head. I purchased a separate amplifier and just ran the antenna lead to this amplifier. Reception was still pretty good but I got really tired of going outside to see which way the antenna was pointed.
I had the Concord removed and the opening sealed with a metal plate and lots of Dicor. I now use an omni antenna. Not as good as the Jack but I don't have to point the antenna. I also stream Youtube TV over the internet most of the time.
For early Concord antenna owners. I was told by Concord that the amplifier does not amplify UHF signals, only VHF. So just about any new directional antenna you get will be better than the Concord.
