A TV antenna may seem like a simple device but it is more than a receiving device to get clear images on your TV. This is why even if you can install some types of antennas easily by yourself (such as indoor antennas) it is still best to have a professional cable TV technician install or repair your aerial or TV antenna.
What is a cable TV antenna?
A TV aerial or a cable television antenna is a device made up of (ideally) lightweight metals and cables to receive radio frequencies coming from transmission towers for clear images for your television.
There are several parts of an antenna that may differ with every type, but the most common and basic parts are coaxial cables, reflectors, poles, directors, circuit boxes, and stand or base.
What are the parts of an antenna?
The main cable (which is the coaxial cable) is the electrical cable that connects the entire antenna device to your television. These cables that are made up of electrical conductors are carefully insulated to transmit clear radio frequency signals.
Antenna reflectors and directors are either stand-alone devices or integrated with the antenna set-up. They are parts of the antenna that directs or reflects radio frequencies that could modify, gain, or re-direct the reception of the signals.
The circuit box, poles, and base hold the whole antenna device together keeping it in place for mounting.
What are the types of antenna?
There are several types of antennas depending on how frequencies are transmitted, on its mobility to be routed to just one or numerous directions, on the amount of frequency that it can receive, and on where it is installed.
An antenna can be digital or analogue based on how it receives transmission. Digital antennas receive and transmit signals in a form of compressed data in digital packets. On the other hand, analogue antennas receive and transmit radio frequencies over the airwaves.

Antennas are also classified according to the amount of frequency they receive. Antennas can be Very High Frequency (VHF) or Ultra High Frequency (UHF) or a combination. Very High Frequency (VHF) antennas can receive frequencies from 30 megahertz up while Ultra High Frequency (UHF) ones can receive higher than 300 megahertz. A combiner or splitter can be used to receive transmissions at different frequencies.
An antenna can also be built to receive transmissions from a single direction or it can receive transmission from different directions. It can also be set up indoor or outdoor. An indoor antenna is easier to set up but an outdoor one can be maximized to get the possible reception. It is advisable to have a professional install your outdoor antenna for your safety and proper installation.
How does a cable TV antenna work?
An aerial or a TV antenna receives radio frequencies emitted by the nearest transmission towers of the cable TV provider. These frequencies are then transmitted to your tuner bringing to your TV clear images from different TV channels because of the best TV reception care of your cable TV antenna.
How do you get the best TV signal in Sydney?
Sydney is an expansive city with lots of infrastructures, trees (in some areas), and a relatively dense population that competes with the best TV reception possible. To get the best possible reception, you must consider the following factors:
– your area and its distance to the nearest transmission tower
– the kind of antenna you are using and its components
– your cable TV antenna installation and maintenance
If your location is near a transmission tower, lucky you, you won’t have to do much to get the best reception. If you have a powerful antenna – such as a digital, UHF, multi-directional antenna for example – you are all set. But if your location is a bit far from the transmission tower, you will need a higher-powered antenna and have a professional technician install your antenna for you.
Professional technicians would know where to install your antenna to get the best possible reception, if necessary, remove possible obstructions, choose the right antenna that you need, and provide the proper maintenance.
What are the features of an antenna to get the best reception?
There are features of an antenna that can be maximized to get the best signal for your TV.
First, your antenna must be compatible with your TV transmitter and the transmission requirements of your location – i.e. your distance to the nearest transmission tower, the recommended antenna for you by a professional, etc.
Check if your antenna is properly installed. It should be in the line of direction of the nearest transmission tower with minimal obstructions. There is also a standard height to mount your antenna and a professional technician knows this.
If you are not within the ideal distance from a transmission tower, a TV antenna booster or signal amplifier can be used to improve your TV reception.
What to check if there is a signal interruption?
If you experience signal disturbance with your cable TV viewing, here are what you need to check with your antenna:
- Main or Lead-in Cable. The lead-in cable is the main cable linking your antenna to your device. It should be fully-layered to avoid unnecessary radio frequencies and other interference from other sources.
- High Isolation RF Splitter. You must also check the high isolation splitter if you have it in your cable TV antenna setup. This is the device that allows you to connect your antenna from 2 TV units to as many as 8. However, you must note that whenever a signal is split, it loses power. The splitter is needed so that each split does not impact another port or signal split.
- TV Tuner. Your tuner may be built-in or a separate top-box tuner. This is the part of your TV antenna set-up that drives the other parts to where the best signal reception is. Even if you can easily receive the best signal but you have a defective tuner, you still won’t transmit that signal to your TV.
Poor signal reception or interferences are sometimes easily remedied at home such as a simple re-direction of your antenna to changing a cable. However, for your safety and assurance, it is still best to consult with a licensed professional cable TV antenna technician.
