What type of antenna do I need?
|
|
|
|
A friendly Technician will carry out an analysis using a digital strength meter to measure where the optimum signal is received from and can advise you on all that you can receive in your area, and recommend the most suitable Antenna.

UHF Antennas
To receive signals from the transmitters mentioned, a UHF antenna is required and in many cases an amplifier/booster is also required.
Here are a few examples of what a UHF antenna can look like. In general they are much smaller, the elements are close together and are better looking than a VHF antenna

VHF Antennas
Brisbane (Mt Coot-Tha) Also has a beam that broadcasts TV signals to many areas on the Sunshine coast. To receive these signals a VHF antenna and a UHF antenna is required, or a combination antenna that incorporates VHF and UHF signals. An amplifier is most definitely required to receive these signals on the coast. The signals for analogue are acceptable but the digital signals work ok during the day but can often tend to break up when there is a storm, or at night.
Here are some examples of VHF and Combination Antennas

How does it get to my TV?
|
|
|
|
Antenna systems work just like a water system
|
|
|
|
|
Antenna
|
Water Tank
|
|
Collects signal
If behind a tree it does not get good signal
If rusted, or damaged never receives all of the signal.
|
Collects water
If under a tree it does not fill up
If rusted and has hole in side of it. It Never fills up to its capacity

Amplifier
|
Water Pump
|
|
Increases Available TV signal
If power is turned off no signal gets to TV
If poor signal is received then will only amplify the available signal
|
Increases available water pressure
If power is turned off no water gets to destination
If tank never full will only pump what is available in the tank.
|
|
|
|
Splitter
|
T - Joiner
|
|
Splits TV signals to more than one TV point
The more TV points you have the weaker the signal gets at each point
If poorly connected, signal is lost
|
Splits water to other taps
The more taps you have the weaker the pressure will become at each tap
If poorly connected, water leaks and water is wasted

Coax Cable
|
Water Hose
|
|
Allows TV signal to pass through to its destination
If the cable is kinked it restricts signal flow
If cable has a damaged outer shield signal leaks out or interference gets in
If cable is joined with electrical tape significant signal is lost
|
Allows water to flow through to its destination
If the hose is kinked it restricts water flow
If the hose has holes in it water leaks out
If hose is just joined with electrical tape water leaks out.

Antenna Point
|
Water Taps
|
|
This is where we want good signals for our TV
If it is loose or rusted signal is lost
If not connected with digital type fittings digital may not work like it should the TV will never receive all of the signal.
|
This is where we want the water to be available from
If tap leaks water is wasted
If an imperial tap has been fitted then metric hose fittings will not work or fit

Amplifier Power Supply
|
Water Pump power plug
|
|
Provides power to the amplifier
If removed amplifier will not function
Will normally only work from one TV point
Works by feeding a small voltage up the coax cable
When fitted correctly will allow TV signal to flow to all TV points
|
Provides power to water pump
If plug is removed pump will not run
Should only be plugged into a socket with a safety circuit on it
