- Run "auto scan" or "channel scan" with the input set to Antenna or Air.
Menu names vary by brand: see antenna setup by TV brand and when and how to rescan.

Plan on an attic or outdoor antenna in Longmont
Antenna type: Attic or outdoor.
- The farthest main network, PBS (KRMA-TV), is 35 miles away
- ABC, CBS, FOX, PBS and The CW are rated Moderate, so placement matters
- Main network towers are south and southeast of the city, so one fixed aim may miss some
Do you need an amplifier?
An amplifier, ideally a preamplifier mounted near the antenna, can help with the farther stations, such as KRMA-TV at 35 miles.
Splitting the signal to more TVs weakens it at each one. With 2 or more TVs, a powered distribution amplifier keeps every TV's signal strong. One antenna, several TVs
Compare indoor, attic and outdoor antenna types, and read the outdoor antenna safety overview before you go on the roof. Older TV without a digital tuner? See converter boxes.

Spanish-language channels in Longmont
Canales en español
6 Spanish-language channels reach Longmont at a Strong or Moderate signal. They come with the same antenna after a channel scan.
Where to point your antenna
Aim south-southeast (157°). Rings at 5, 10 and 30 miles from central Longmont; dots are Strong-signal towers.
- KDEN-TV and 2 other stations: 12 miles east-southeast
- K22NW-D and 2 other stations: 16 to 20 miles south-southwest
- KQCK: 27 miles north
Placement and interference tips
- Place the antenna on a south-southeast-facing window or wall. Higher is better.
- The farthest main network tower is 35 miles away, so an attic or outdoor antenna will do better than one inside the living space. Attic antenna guide
- 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 Longmont
NextGen TV (ATSC 3.0) is on the air in Longmont, 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).
