Lost a channel?

No network has changed stations in the Denver area in the past two years. If a channel goes missing, a rescan usually brings it back.

Rescan in 3 steps

  1. Open your TV's settings.
  2. Find the channel, broadcast or antenna section.
  3. Run "auto scan" or "channel scan" with the input set to Antenna or Air.

Is the station hard to receive here?

KFCT (channel 22.1), K22NW-D (channel 12.1), K24HQ-D (RF channel 24), plus 4 more, are weak in Thornton; they may come and go. If a weak station is the one you're missing, these steps can help.

Recommended for Thornton

A multi-directional indoor antenna fits Thornton

Antenna type: Multi-directional indoor, with VHF reception.

KMGH-TV (ABC, channel 7.1) broadcasts on VHF, so choose an antenna rated for VHF as well as UHF.

How to choose an antenna for VHF channels

  • ABC, CBS, NBC, FOX, PBS and The CW are all within 23 miles
  • Main network towers are southwest and north of the city, so one fixed aim may miss some

Do you need an amplifier?

Try without an amplifier first. Add one only if channels break up. The farthest main network station, KRMA-TV, is 23 miles away.

Splitting the signal to more TVs weakens it at each one. One antenna, several TVs

Where to point your antenna

Aim southwest (235°). Rings at 5, 10 and 30 miles from central Thornton; dots are Strong-signal towers.

5 mi 10 mi 30 mi N E S W Main towers KDEN-TV +2 KRMA-TV +2 K12XK-D +2
  • KMGH-TV, KCNC-TV, KWGN-TV and KDVR and 18 other stations: 20 to 26 miles southwest
  • KDEN-TV and 2 other stations: 12 to 13 miles north
  • KAVC-LD: 15 miles west
  • KXDP-LD: 19 miles west

Placement and interference tips

  • Place the antenna on a southwest-facing window or wall. Higher is better.
  • LED bulbs, especially older or cheaper ones, can interfere. If reception gets worse when the lights are on, that's the cause.
  • Living near a cell tower? An LTE filter can block the interference.
  • Trees and hills block signals (Cord Cutters News covers these and the LED and cell tower problems), and so do metal roofs and foil radiant barriers in attics (Solid Signal). Move the antenna away from them if you can.

NextGen TV in Thornton

NextGen TV (ATSC 3.0) is on the air in Thornton, broadcast from KHDT-LD and KWGN-TV. Any antenna receives it.

  • Your current TV keeps working. Today's broadcasts continue alongside NextGen TV: full-power stations that switch must keep simulcasting their main channel in today's format (CommLawCenter).
  • You need an ATSC 3.0 tuner to watch it. That means a TV or tuner box with one built in. Most TVs don't have one (PCWorld).
  • Some channels are encrypted. Some broadcasters encrypt their NextGen TV channels, and some tuners and DVRs can't play encrypted channels yet. HDHomeRun devices are one example (Antenna Land). Check before you buy, especially a DVR.
  • No shutoff date yet. Broadcasters have asked the FCC to end today's broadcasts in large markets around 2028 and everywhere around 2030. The FCC hasn't set a date (PCWorld).
