A Perfect Picture in an Imperfect World
Why do signal reception problems happen?
The answer to this question belongs in the endless list of reasons why things don’t work perfectly in an imperfect world. Without being too technical and taking you through Electromagnetism 101, here are the reasons why most digital TV signal problems arise.
Digital TV Antenna Problems and Specs
An antenna with an improper gain, direction, height or bandwidth is likely to lead to reception problems. The following information can help you choose the correct antenna for your digital television.
- VHF and UHF Antenna: Your rooftop (or indoor) antenna receives TV signals transmitted by free to air TV stations. In Australia, digital TV signals are aired on both VHF and UHF frequencies (the signals are electromagnetic waves and the frequency is the number of waves transmitted in one second). UHF signal has a higher frequency than VHF and is vertically polarized in Brisbane, while VHF TV signal travels in the horizontal plane. VHF and UHF TV signals thus require horizontal and vertical antennae respectively. Also, VHF antennae are generally bigger in size than UHF antennae. In Brisbane, you require a hybrid VHF/UHF antenna if you are in the city, while a UHF antenna will do at most places in the suburbs.
- The ‘Gain’ of the antenna is a reflection of its reception capability. You need a lower gain antenna if the signal at your location is strong, mostly when you are close to the transmitter. Conversely, a higher gain antenna is more suitable when the signal is comparatively weaker. Moreover, you also need to mount the antenna higher if you are located far from the origin of the TV signal. Australian government recommends the following guidelines for deciding the installation height and gain of your digital TV antenna.
Antenna Gain and Mount Height Urban/Suburban Rural Band III 5 dB at 5 meters 8 dB at 10 meters Band IV 8 dB at 5 meters 11 dB at 10 meters Band V 9 dB at 5 meters 12 dB at 10 meters
- Bandwidth: Bandwidth tells you which particular frequency bands the antenna can receive. In Australia, digital TV signal is transmitted in Bands III, IV and V. Band III falls in VHF and has channels from channel 6 to 12. Band IV and V are UHF frequency band that contain channels 27 to 35 and 36 to 69 respectively. All these channels are being used for digital TV reception in Australia, with the exception of channel 27. Depending on the specs of your digital equipment, you should get an antenna that receives on all or most of these bands.
- Direction: The backend of the antenna must point straight towards the direction of the signal. While it may be easy to see the direction by looking at the TV station if you can see it, finding the precise direction of the signal may be problematic at locations farther away from the transmitter.
- Condition: Old, dilapidated or messy antennas are likely to have poorer reception. Bird droppings, rust or broken rods deteriorate the quality of signal.

Cable and Connectors
If you are sure there’s nothing wrong with the antenna, the next thing you need to look at are the connections between the antenna and your digital TV (or set top box) if the reception problems persist. Australian government recommends an RG-6 cable or above for optimum reception results. Make sure that the cable is securely connected with the roof or wall socket at one end and your antenna at the other. Any connectors you use must be F type, dye cast connectors so that signal quality does not suffer a loss. Use only powered splitters if you must. Check the connectors on your wall socket and behind your TV or set top box. See that there are no loose joints, broken cables or bad connectors.
TV Signal Boosters
It may be possible that the digital television signal at your location is too weak to be picked up by the antenna alone. You may require a booster to step up the signal strength. A mast mounted signal booster is usually used in Brisbane and the Sunshine Coast areas; however, a set top booster may also be used in some locations. It is better to rely on professional help for deciding the type of booster you may need. Be careful to check the signal strength before you install a booster, as a booster may amplify an already strong signal beyond receivable limits and worsen your problems.
Interference or Blind Spots
Other common reasons for poor digital TV reception can be the electromagnetic interference from your household appliances or cell phone signals. Interference from ground obstacles or other strong transmitters in the area can also distort the digital television signal and cause blind spots in its coverage. The solution may be to change your antenna location, height or both.
