The HBU22 was my best suggestion of a 1 antenna that would almost get every thing.
You said that you did not know anything.
Now knowing that you are building a silacondust and etc. system , I recommend a Winegard HD7694P antenna that receives VHF high band channels 7 thru 13 and UHF band channels 14 thru 51 aimed at about 195 degree magnetic compass.
If you would really like to go all out , Install a HD7082P as the first antenna.
The HD7082P receives all the Tv channels , VHF low band 2 thru 6 , VHF high band 7 thru 13 and UHF band 14 thru 51.
There are currently no receivable VHF low band channels 2 thru 6 at your location , how ever there might be in the future.
As I recall a VHF low band channel 5 transmitter recently started transmitting along the front range at another location , I am looking it up and will return with the info.
I am not trying to un decide the situation , The HD7694P antenna is good for now and into the future.
