Channel 31 is on the UHF band. The above tuning information applies to both television sets and video recorders. Most reception problems, where interference is suspected, are caused by deficiencies in television/video cassette recorder receivers, by inadequate or faulty antenna installation or by people trying to receive stations that are too distant for reliable reception.
A good outdoor antenna will help resist interference by increasing the desired signal. Generally, indoor antennas are too small to work effectively. They are also more likely to pick up electrical interference from the wiring in your home. Antennas are designed for a particular signal level. If you live near the outer edge of the area serviced by Channel 31 you will require a higher performance UHF antenna than people living close to the transmitter. You will also need to point your antenna at Mt. Dandenong.
A good quality coaxial cable is recommended to receive Channel 31. The common Ribbon types are not suitable for UHF television signals. It is also important that the right antenna lead connections have been used throughout your television installation. The cure for many reception problems is simply to repair the antenna lead connections at either end of the cable.
