Find out where the signal for your HDTV channels are coming from. You can contact the stations directly or use online resources, such as the TV Signal Locator.
Purchase an HDTV antenna that includes both VHF and UHF signal reception.
Check to make sure the VHF reception on the HDTV antenna includes high-band and low-band reception.
Find out if the antenna can be used outdoors. HDTV signals can often be picked up better when the antenna is located outside.
Mount the antenna as high as you can using a 75-ohm coaxial cable. If you're mounting it indoors, try to get it to an upper floor or the attic for installation. Outdoor antennas should be mounted on the roof or as high up as possible. The mounting equipment, such as brackets and screws, should be included with the antenna.
Face the antenna toward the area where the signal is being broadcast. This can help improve reception. Adjust the antenna while someone else checks the channels and tells you how the reception is coming in.
