How to install a UHF aerial

Installing a UHF (Ultra High Frequency) aerial can be a straightforward process,

But it’s important to follow the steps carefully to ensure that the aerial is properly installed and functioning. Here are the general steps for installing a UHF aerial:

  1. Choose a location for the aerial: The ideal location for a UHF aerial is on the roof, in a location that has a clear line of sight to the transmission tower.
  2. Assemble the aerial: Most UHF aerials come in several pieces that need to be assembled. Follow the manufacturer’s instructions to properly assemble the aerial.
  3. Mount the aerial: Use the mounting hardware provided with the aerial to secure it to the roof or other mounting surface. Make sure the aerial is level and secure.
  4. Connect the coaxial cable: Use a coaxial cable to connect the aerial to the TV or other receiving device.
  5. Perform a signal test: Once the aerial is installed and connected, perform a signal test to ensure that it is functioning properly. You can do this by using the TV or other receiving device’s built-in signal strength meter.

If you are not comfortable with installing the aerial yourself, hire EasyTV to do the installation for you. 🙂

Different types of UHF aerials

There are several types of UHF (ultra-high frequency) antennas that are commonly used for television and radio reception. Some of the most common types of UHF antennas include:

  1. Yagi antenna: This is a directional antenna that is often used for long-range reception. It consists of a series of parallel elements arranged in a line, with a reflector element at the back and a driven element at the front. Yagi antennas are relatively easy to install and are a good choice for those who want to focus their signal in a specific direction.
  2. Bowtie antenna: This antenna is shaped like a bowtie and is often used for indoor or outdoor reception. It has a wide beamwidth, which means it can pick up signals from a wide range of directions.
  3. Dipole antenna: This is a simple antenna that consists of two conductive elements (usually wires) that are separated by a small distance. Dipole antennas are often used for VHF (very high frequency) and UHF reception and are relatively easy to build.
  4. Log periodic antenna: This antenna is designed to have a wide frequency range and is often used for UHF and VHF reception. It consists of a series of elements arranged in a line, with the longer elements at the front and the shorter elements at the back. Log periodic antennas are relatively easy to install and have a good signal-to-noise ratio.
  5. Flat panel antenna: This is a relatively new type of antenna that is designed to be mounted on a flat surface, such as a wall or ceiling. Flat panel antennas are often used for indoor reception and can be hidden behind a picture frame or other decorative element.

What is UHF?

UHF stands for ultra-high frequency and refers to the electromagnetic spectrum in the range of 300 MHz to 3 GHz. This frequency range was first identified and used in radio communication technology in the early 20th century. It was initially developed for military and government applications but has since become widely used for a variety of purposes, including television broadcasting, wireless networking, and wireless communication devices. There is no one person credited with the invention of UHF, as it has evolved over time through the contributions of many individuals and organizations working in the field of radio communication technology.

How far can UHF travel?

The range of a UHF signal depends on a number of factors, including the power of the transmitter, the type of antenna being used, the presence of obstacles such as buildings or mountains, and the type of terrain. In general, UHF signals tend to have a shorter range than lower frequency signals, such as those in the VHF (very high frequency) range. However, UHF signals can still travel fairly long distances under the right conditions.

For example, a UHF television signal transmitted from a high-power antenna can travel up to 100 miles (160 km) or more under favorable conditions. A UHF radio signal transmitted from a handheld radio using a small antenna may only have a range of a few miles.

It’s also worth noting that UHF signals can be affected by atmospheric conditions such as rain, fog, and temperature inversions, which can reduce the range of the signal.
