Antenna Systems FAQ
Q - What kinds of signal does my antenna recieve?A - In TV terminology, there are basically 3 different types of signal - VLF (Very Low Frequency), VHF (Very High Frequency) & UHF (Ultra High Frequency). In Australia, the predominant usage of signal is VHF in major cities & UHF for semi-regional areas or newer transmission towers. VLF & VHF signals can suffer more from interference from things such as electrical or sparking devices, or even from bad weather in low signal situations, while UHF is largely interference free.
Q - What kind of antenna do I need?A - There is no single answer to this question, as there are so many variables which can affect what you will need. There are also a wide variety of antenna types. In domestic installations, the two most common types of antenna are the Phased Array & Yagi type. Taking a look around your local area will give you at least some idea of what kind of antenna will be the most suitable for your particular location. We suggest that a professional installer is the best way to go.
Q - Will I need a signal booster?A - As with the last question, this cannot be answered simply. If you are seeing 'noisy' pictures, then providing that you do not have any faults in your system, it is a possibility that a signal 'booster' or amplifier will assist in gaining better picture quality.
Q - What kind of cable is the best for my antenna?
A - The current recommendation for cabling is for quad-shielded coaxial cable. The extra shielding as opposed to single or dual shielded cable assists ny providing better conductivity for signal pass-through, but also should assist in reducing any outside interference from electrical devices or other external factors.
Q - My pictures are terrible, should I mount my antenna higher?
A - Once again, this is a very complex topic & there is no single answer which can assure you of a solution. If you are recieving VHF signals, then there is a good chance that raising the height of your antenna may help you to receive better pictures. If you are recieving UHF signals, then there is no real benefit in putting your antenna on a huge mast in many instances. Once again, positioning of your antenna is best left to a professional installer.
Q - Can I spread my satellite or cable receiver pictures to the rest of the TVs in my house?
A - Yes, there are a variety of methods whih can be used for this purpose, including wireless AV senders or combining the signal from your reciever to the antenna system in your house.
Q - How do I recieve digital TV, will I need a new antenna?
A - Assuming that digital TV is already being transmitted in your area (visit the Digital Broadcasting Association website to find out), you will need firstly, a receiver capable of decoding digital TV signals & secondly, your antenna system must be in relatively good condition. It is quite possible that you will not need to do anything other than purchase a digital receiver to view digital TV. You will need to bear in mind that many antenna systems contain older style amplifiers & splitters which can prevent or interfere with the reception of digital TV. If your antenna system is relatively new, it is likely that you may not need to do anything for reception of digital TV. If your current analogue reception is good, or at least average, there is a good chance your antenna system will cope with digital TV.
