We recommend to get a local, qualified antenna technician to service your reception equipment regularly. High voltage power lines can cause electrical interference. Hot, dry and windy weather can cause power lines to spark. At night, dew falling on power lines with dust, salt or pollution damage can cause interference.
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.
This interference may be caused by equipment in your home, such as hair dryers, sewing machines, electric drills, doorbell transformers, light switches, smartphone chargers, power supplies, computing devices, washing machines, clothes dryers, fluorescent lights, LED lights, or garage door openers.
Repositioning the antenna is the best way to correct this type of interference. Placing it as high as possible will help avoid bounced signals. If you aren't able to install an outdoor or attic antenna, a window-mounted one might be your best bet.
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.
Luckily, there is little chance of that, because Wi-Fi networks work on different frequencies than digital antennas. Digital TV antennas go up to a frequency of 693.25 MHz, according to Into Tomorrow. Wi-Fi routers, on the other hand, operate on 2.4 GHz or 5 GHz. That's a huge gap between frequencies.
Loose cables, incorrectly tuned televisions or set-top boxes and faulty aerials are the most common reasons for reception problems.
According to our research, antenna channels may be lost for various reasons. The reasons include a faulty antenna, lack of digital conversion, coaxial cable signal loss, signal interference, LED light bulbs, TV settings, a faulty TV video card, electric pumps, and thermostat-controlled chlorinators.
If you suffer from reception problems in the evening, this suggests that the signal getting to your television is not quite strong enough. Changes in the weather, temperature or atmospheric pressure can cause an already poor signal to break up or be lost.
The digital TV signal is a 'line of sight' signal. Typically, the higher you have your antenna, the better the reception. While signals pass through walls and other surfaces, the more obstructions the signal encounters, the weaker the signal and this causes signal disruption.
This is often a result of either the TV box being powered off, not being properly connected to the TV, or the TV being set to the wrong input. In some cases, if you are not receiving a signal on your TV, it could be a result of a service outage.
This is an indicator of a poor signal. Pixelation can be caused by weather conditions (thunderstorms), interference from nearby appliances or signal interference from other devices.
If your TV image is pixelated, or broken up, the first thing to do is check all your connections. Loose connections are often the cause. Unplug and reconnect the coaxial connections between your Set-Top Box and your TV and your wall connection. When you plug them back in, make sure all connections are secure.
Everything from elevators to poorly shielded TVs can create interference. When in doubt, move your router 5 to 6 feet away from other electronics.
Larger antennas have typically better performance than smaller ones. Gain/directivity is not available from a very small surface area. Know and understand your antenna radiation patterns. Point antennas gain towards users.
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.
and fair to weak signal areas an antenna should be installed between three to five feet above the peak of your roof to give good line a sight but you want to make sure the mass is stable.
Position the antenna higher on the wall
However, this is just a general rule; the construction of your house, the orientation and position of the wall, and whatever is on the other side of the wall might actually cause worse reception if you mount the antenna high up.
Your TV may need Re-tuning
This is often the case when people move into a new house and lose signal. You will more often than not need to retune your TV so that is tuned into the transmitter that your antenna is aligned to.
HDMI, or “High-Definition Media Input,” is the go-to port for all your modern devices. HDMI ports in your TV are used for both video and audio.
The simplest and most convenient way to check whether it is the aerial socket or TV that is causing problems is to check if everything is working with another TV. If you have a second TV in your home, connect it to the aerial point that you find problematic. After that, wait for the TV to scan for the channels.
