I lived in northern Colorado for 12 years at Fort Lupton Colorado.
I have been through and to Burlington and the surrounding area many times , nice and flat area.
For a one antenna solution of reception of the Colorado repeater Tv stations to the north west and the Kansas repeater stations to the east.
Install a Antennas Direct , Clear Stream 4 UHF antenna - with a Antennas Direct CPA-19 preamp - aimed at about 300 degree magnetic compass direction.
The 300 degree aiming direction is a in between aim direction so the front and back of the antenna is aim in the directions of north west and east.
Here is how to aim antennas ,

The Kansas Tv stations , KBSL CBS and KWKS PBS are strong signal strength and will most likely be received through the back side of the antenna , KLBY ABC is weaker of signal strength and may not be received through the back side of the antenna.
If not and you will like to receive KLBY then remove a reflector screen from the antenna. Standing at the back of the antenna , facing the reflector screen remove the right side reflector screen. Removal of the reflector screen will let more signal get to the reception loops from the Kansas repeater stations.
Here is what is on the Colorado repeater stations.

K16EK-D UHF channel 16 , CBS.
