What is a Cable TV Antenna?

A television antenna or a TV aerial is a device made up of metals (preferably lightweight ones) and coaxial cables. It is connected to your television set to receive radio frequencies from the nearest transmission tower.

What are the Parts of the Antenna?

Parts of the antenna differ with every type, but the most basic parts are reflectors, directors, poles, circuit box, stand or base and coaxial cables.

Part 1: Antenna Reflector

The antenna reflector can be a stand-alone device or is integrated within an antenna that bounces off radio frequency energy. This modifies the radiation or energy and thus increases the gain of radio frequencies.

Part 2: Antenna Director

The antenna director, on the other hand, points or focuses on the emission of radiation in a given direction.

Part 3: Poles, Circuit Box, Stand Or Base

The poles, circuit box, stand or base are what keeps the antenna in place. They are what holds the antenna together for it to be mounted properly.

Part 4: Coaxial Cable

The coaxial cable is the electrical cable connecting the antenna to your television. The coaxial cable or coax are made up of layers of insulated electrical conductors that transmit radio frequency signals.

How Do TV Antennas Work?

TV antennas capture radio waves from the nearest transmission towers from the subscribed cable TV provider and then transmit these radio frequencies to your television’s tuner which then extracts the television signal that brings to your tv, the desired channels and best possible TV signal. 

What are the Types of Cable TV Antennas?

Based on the quality of the signal that you are receiving in your area, you can choose the right type of antenna to get the best possible reception.

Type 1: Digital or Analogue

The difference between the two is how radio frequencies are transmitted from the tower to your cable television. Analogue antennas or analogue transmission transmit radio signals through the airwaves while digital transmission transmits compressed data in digital packets.

Type 2: Very High Frequency (VHF) or Ultra High Frequency (UHF) or a combination

Radio frequencies transmitted by cable TV antennas are measured in megahertz.

30 megahertz are considered very high frequency while it is considered ultra-high frequency if it is anything higher than 300 megahertz. A combiner or splitter may also be used to receive signals at different frequencies.

Type 3: Uni-directional or multi-directional

Antenna types are also based on the direction they receive signals. Some antennas are uni-directional or receive signals from only one direction or they can be multi-directional where they can receive radio frequencies from different directions.

Type 4: Outdoor or Indoor Type

An antenna can also be indoor or outdoor. An indoor antenna can easily be set up inside your home. Though most prefer the outdoor antenna, set up by professional technicians to get the best possible signal reception for clearer images on your television set.

How Do You Choose the Antenna that’s Right for You?

There are several things to consider before installing your TV antenna. First, you must get an antenna that is compatible with your device or television set. Some TVs require a digital antenna, while some still need an analogue antenna to function.

You must also consider your distance to the nearest transmission tower. If you are a bit far from it, you will need a high-powered antenna and preferably an outdoor one. You must also consider if there are plenty of interference to your antenna like electrical lines, trees, buildings, etc.

If you find it hard to choose what’s right for you, you can always call a professional licensed technician, to have your area and your device checked for the right antenna.

It is always safer and better to consult with professionals when it comes to your cable TV antenna. You do not have to climb heights and figure out cable wires and where they should connect to, all these while you are assured of a good TV signal so you can just sit back and relax and enjoy your favorite show.
