LG does not have a list of recommended indoor or outdoor antennas that can be used with the LG 77" Class C5 Series OLED evo AI 4K UHD Smart webOS TV (2025), Model # OLED77C5PUA. AS with all other LG TVs, regardless of type, this TV features an F-Type, 75-Ohm Coaxial connector on the back labeled 'Antenna/Cable In' that you can connect an indoor or outdoor antenna to. Antennas do not use brand-specific technology. Whether you have a Samsung, LG, Sony, TCL, or Vizio, the antenna connects to the standard "Antenna/Cable" threaded input on the back of the TV. Choosing the right TV antenna depends primarily on your distance from local broadcast towers and local terrain. You can use online mapping tools to find tower locations and required signal strength, and then decide between indoor or outdoor setups based on your exact address and HOA rules. Before buying anything, look up your specific address to see how far you are from broadcast towers and which channels are available. An Online tool will give you color-coded recommendations based on CTA standards that show whether you need a multi-directional or directional antenna. DTV Reception Maps is an official FCC tool that predicts signal strength and displays channels available at your location. Indoor Antennas are ideal if you live within 30 miles of broadcast towers and have clear lines of sight. They are usually flat, amplified, or unamplified, and plug straight into the TV. They are best for urban areas, but struggle if there are large trees, mountains, or thick building materials (like concrete/steel) blocking the signal. Outdoor/Attic Antennas are necessary if you live in the suburbs or rural areas (40+ miles away), or if you want to pull in channels reliably from weak signals. These are larger, typically mounted on a roof or in an attic, and offer superior reception and less interference. Mileage ratings are just estimates. If you are 30 miles away, a 50-mile antenna should work well, but beware of over-promising 100+ mile ranges. Most U.S. channels broadcast on UHF. However, check your signal map to see if your local channels are broadcasting on VHF frequencies so you can ensure your antenna supports both bands...^Ivan.
