I live on the step of a mountain range, high above my city and virtually all of the TV and radio antennas are just around the bend from me so we receive - 0 - TV channels in this house (which we custom built 20+ years ago) and just a few radio stations. We do not have cable or natural gas service within 1 mile of this location.
With that in mind, I DO have Dish network and have always done all the installation of equipment myself (or with VERY strict oversight by me).
I wired this house myself for not only electricity but for telephony and RG-6 coax as well. I installed the coax for the Dish dish while building the house.
My friend is a Dish and DirectTV rep in the area and when I need a new box, he hands it to me and I install it, then return the old box to him.
Currently we run a 722 without a ‘Joey.’
I can assure you that Dish has NO special equipment in your house screwing up your coax, unless you have a ‘Joey’ - which could possibly block/override your OTA antenna.
If you have removed the 322 (and your Joey, if you have one) then you likely just need a good RG-6 coax from your antenna to the TV...
Is your TV newer? Does it have a tuner for OTA broadcasts? A few do not have this.
If it does, look through the menu on the TV for digital OTA and see if there is a ‘setup’ or ‘find stations’ menu. That may do the trick.
Best!
Both tvs are 1080p Panasonic plasmas - about 5 years old. Both have digital tuners. After I connected the antenna, I ran the set-up channel scan for both analog and digital signals. Moved the antenna a bit and tried again. I don’t know what a “Joey” is. Is this the model 322 box that feeds one tv a wireless signal? Could there be another component of the system I am not aware of? I did disconnect all the Dish equipment that I know of. But the fact that the Channelmaster rep told me there is hidden equipment in the house that interferes with the antenna is just too weird. He told me to check all the wiring in the house. Oh, for “liability reasons” he can’t tell me what or where it is. Anyway, thanks for helping!
