Greetings,
By a long shot, you will be much better off with a Winegard
7694P. Home Depot can get you one, including shipping, for
$48.86 It is very sturdy and quite compact. Works great!

MCM electronics sells antennas inexpensively. You might
wish to consider a 4 bay UHF aimed towards Cheyenne with it's own dedicated cable in addition to an antenna pointed towards Denver.
Be sure to wrap the insulators (plastic parts) with some electrical
tape. At the end of each, twist the tape so you have sticky to sticky
side. It helps keep things neat and it protects against the wind and
summer sun......
