When the weather is terrible, and there is nothing left to do, we always turn to the television to pass our time and relax. But, unfortunately, bad weather affects our antenna signals. It is frustrating to have something that affects your television reception, and there is nothing you can do about it. We have to accept that weather is one of the biggest affectors of our antenna and our television reception.

Different weather conditions bring various problems, and it is always good to know how they affect your antenna and television reception to prepare for it. Common antenna problems that may occur with weather interference are:

Rain

Rain affects the antenna and the television reception because raindrops absorb power from the signal. As a result, they scatter the signal and cause interference. Imagine a signal hitting a raindrop and then sprinkling in multiple places. The signals will never reach your antenna!

In addition, rain increases the atmosphere’s density and is a natural barrier between a satellite-mounted transmitter and your receiving satellite dish. Aside from that, water droplets on the transducer and the satellite dish mirror, optical lenses, for example, interfere with the signal and affect the antenna. As a result, channels with the weakest transponders stop showing; the pictures then break and fall into cubes, ruining your television show.

Winter and Snow

Certain pressure situations happen during winter. For example, cold air gets trapped in a layer with a temperature inversion instead of the air getting cooler steadily when moving from the earth and through the troposphere. Therefore, if towers are actually inside a cold layer, or if signals hit the bottom of a cold layer, signals from outside your normal viewing area may reach your antennas and cause interference.

At lower temperatures, rain or snow can also freeze and interfere with reception. Due to foreign bodies like snow, satellites can no longer reflect signals properly. When signals are not reflected correctly, they will never reach the receiving unit. How can your television shows play when your antenna never received the signal?

Wind

Winds cause poor reception because of the electrostatic charge of storm clouds which block the signal from the satellite system and the transmitter, generating poor television reception. Likewise, when thunderstorms occur, the atmosphere becomes electrostatically charged, interfering with the movement transmitted to the receiving satellite dish, resulting in a static television show.

A strong wind can affect the signal, but it can also loosen screws of the satellite dish and cause the pans to move over time. It may not be noticeable at first, but the parabolic mirror is no longer appropriately positioned over time. As a result, you can start getting poor television receptions even during perfect weather conditions. When this happens, make sure to call Sydney Cabling https://www.sydneycabling.com.au/ and let them handle your antenna problems for you, especially if you are in the Sydney area. They are widely known as Sydney antenna installation specialists and would be the professionals to call during such occurrences.

Thunderstorms

During thunderstorms, flashes of lightning are bound to happen, and there is a heavy static charge in the air. Due to the heavy static charge in the air, temporary disruptions of service may arise. It is not only the signal affected by thunderstorms; our electrical devices are at risk of getting destroyed during thunderstorms. It is advisable to disconnect electrical appliances from the outlets as lightning strikes can cause electrical devices to malfunction due to overvoltage. We recommend turning off your television sets and grab a book instead.

Heat

High-pressure conditions sometimes occur in hot weather that can create bad television reception. This is because hot weather causes high altitude conditions, causing tropospheric air to cool faster than the air near the ground, trapping lower warm air. When lower warm air is trapped, it creates a border between cold and warm air layers. Signals can then skip along with the cold air layer and travel much farther than they usually could, causing disruption and pixelation from unwanted signals. This phenomenon is called tropospheric ducting.

During summer, people also have difficulty receiving channels due to the phenomenon called “the fading effect.” This phenomenon is even worse for people who are living in coastal areas. Due to the heat, much water evaporates into the air on the sea surface, affecting the television reception and causing antenna problems.

Heat hitting the ground creates different conditions. When a signal passes the heat, it comes off very degraded. Other signals cause echoes that overlap with similar ones; overlapping signals then reach your receivers. Unable to reconstruct a valid signal, your antenna receives a mixed signal, causing static to your television show.

It is very complicated how weather affects your antenna. All I know is that when problems occur with my antenna, I am calling the experts.
