Generally, you get the strongest signal if the maximum amount of the antenna is exposed to the wave, so you should position your antenna parallel to the wave front and perpendicular to the signal direction.
YAGI-type UHF Aerial
These go on your roof-top. Directed at your nearest transmission tower, it picks up UHF signal sent over the air. If your coverage is "Very Likely" then this is the recommended roof-top UHF aerial for you.
The antenna needs to be placed in the same position as the TV transmitter. Because most of the TV transmitter are horizontal polarized it would be best to start putting the antenna in a horizontal position. One For All antennas receive vertical as well as horizontal signals.
Antennas should all be oriented in the same direction, pointing vertically out of the sensor. If the sensor is mounted flat on it's back on a horizontal surface, you should bend the antenna as close to the sensor housing as possible giving you the most amount of antenna pointing vertical.
The end of the antenna with the short elements is the front of the antenna. You point that end towards the TV transmitter.
Your antenna mount needs to be properly grounded for your antenna to function correctly. Without a solid ground, you're bound to get high SWR levels and extremely poor performance.
Averse weather, interference from building materials or terrain, distance from your nearest cell tower, or network overload can all contribute to poor signal.
If hills, trees, buildings, or other geographic features are in between the broadcast towers and the antenna, the signals might not be able to reach your antenna. Elevating the antenna, either by placing it in a higher location or using a taller mast, will increase the signal reception.
Typically, the higher your antenna is placed, the better your reception will be. That's why outdoor antennas tend to pick up so many channels.
For high gain directional antennas commonly called a Yagi, they should be pointed so that the long axis of the antenna should be pointed at each other, just like you are looking down the barrel of a gun.
Antenna Point will identify your location and provide the TV antenna coverage area within 35-mile, 50-mile, and a 70-mile range pattern. The app will help you find the best direction to aim your indoor, attic or outdoor TV antenna.
Higher is always better. Mount the antenna on your roof or in the attic for optimal performance. These locations are more likely to experience fewer obstacles which cause signal interference between the antenna and broadcast towers. Face the front of the antenna toward the broadcast towers.
If you want to focus all of the signal to direct it to a distant target, then the high gain antenna is definitely the best choice. High gain antennas need to be pointed in a preferred direction to send RF signal so that limited signal can be intensified in desired location, as illustrated below.
How to determine proper antenna spacing. As a general rule Southwest Antennas recommends customers place omni-directional antennas a minimum of one wavelength apart from one another, while three wavelengths apart or greater is preferred. This can be easily calculated by hand or by using an online calculator.
If your TV picture is breaking up, cutting in and out, or pixelating (looks like everything is a bunch of squares), then you probably are experiencing a weak signal. Check all of the connections from the wall to your cable box and from the cable box to your TV to ensure that all connections are tight.
The answer to this problem is an aerial tester. TV aerial installers use these small devices to conduct aerial and signal tests efficiently. There are many inexpensive home aerial testers that you can buy online or in electronics stores.
While a strong signal is often thought of as a plus, a signal that is too high will likely cause pixelation or burn out your TV's tuner. Typically a good signal strength is between 60-65dBuV. You can check the nearest transmitters and signal strength available from your location using the MySwitch website.
Overall, placing the antenna as physically high as possible and near a window to prevent interference will yield the best signal. If signal strength is weaker around your home, you should consider an outdoor antenna that you can place on the roof or against the side of your home.
The height of an antenna has a major impact on its performance. Aspects including the feed impedance, radiation diagram, radiation losses, distance from interference, reduction in possibility of exposure to RF radiation, etc.
