Talk to your neigbours in the building You need to ascertain whether the reception problem in your unit is due to a local problem or a building wide problem. If your neighbours say they have good digital TV reception, your reception problems could be due to a faulty or cheap TV fly lead (from wallplate to TV), a faulty or loose wall plate or a cabling fault within your unit. If your neighbours have similar problems, read on. Are you and your neighbours having reception problems with some or all channels? If you and your neigbours in the building are receiving most digital TV channels without interruption, the reception problem may be limited to the antenna, the headend or cabling. If you and your neighbours are not receiving any of the digital TV channels, it could require a major refit of the Master Antenna System. With those overriders in mind, read on... Problem receiving some digital TV channels? Start with the antenna. If the antenna is able to deliver enough signal to the Master Antenna TV (MATV) system, it may be able to overcome other deficiencies within the system. The antenna is probably the least expensive part of an MATV system to replace so it is the best place to start if you have HDTV reception problems throughout the building. Problem receiving some digital TV channels? Check the headend equipment is working properly. The headend equipment is the part of the MATV system takes the digital signal from the antenna and then amplifies and, for larger buildings, processes that signal before distributing through the cabling system. Checking the headend is a relatively straight forward job for an experienced MATV installer. Replacing the headend is relatively inexpensive for smaller 3 storey walk-ups but becomes more expensive with larger buildings where channel processing is required.

Problem receiving some digital TV channels? Check the cabling If the antenna and the headend equipment are working well, then the building may have a number of cabling faults that will need to be fixed. An experienced installer will be able to isolate these faults and, if the cabling is otherwise in good condition, fix those faults. The installer may also be able to rebalance the amplifiers in the cabling system to ensure a more consistent signal is distributed throughout the building. However if cable is generally in a poor condition or is not properly insulated for digital TV reception, it may need to be replaced. This is relatively costly especially if access to the cable risers and conduits is restricted. If replacing the cable, it would also make sense to replace all the wallplates at the same time with screw in F-connector type. Problem receiving all or most digital TV channels? The Master Antenna TV (MATV) system may have been originally designed only for analog PAL TV, and may need substantial upgrade or replacement Your body corporate or owners corporation will need expert advice about the scope and cost of rectification work.
