How To Improve Your

Television Reception

Have you considered a member of the Antenna Technicians Association?

To professionally install or repair your television antenna system?

 The member will, prior to the start of the installation carry out a


With the aid of a field strength meter (not a portable television).

This will determine the following:

•     Location of the antenna (the existing antenna mast/position may not be the best location)

•     Height and direction of the antenna on the mast

•     Type of antenna required (combination, phased array, yagi and channels to be received)

•     Available signal strength (a TV requires 45 dB for good digital picture, analogue 60-75dB for clear picture)

• This allows the technician to determine if an amplifier is required, what type (masthead or distribution) and the level of gain. signal strength  less than 45dB means digital picture drops out, freezes or pixilates.Analogue 50dB


•     The Technical Standards as laid down„by the Antenna Technicians Association Inc.

• Isolated wall outlets or sockets. This helps to prevent possible electrocution from faulty televisions. (Outlets connected to low voltage line powered equipment may prevent this)

• RG 6 / 11 quad screened coaxial cable. (Single screen air spaced cable has greater signal loss at higher frequencies‑UHF, with less resistance to electrical and other interference)

You may also request the technician to demonstrate to you, the expected picture quality on a test television prior to giving your approval for the installation. On completion, the ATA member will record the signal strength of each individual channel and the picture quality on your invoice. 

Whilst members will guarantee their own workmanship and materials used for a specific period, no guarantee can be made or given regarding the reception quality. There are several external factors beyond the control of the technician, which can and do affect the quality of the finished installation, some of which include, but are not limited to the following;

•     distance signal must travel (from point of transmission)

•     objects in the signal path (trees, buildings, hills)

•     seasonal changes (co channel interference, deciduous trees, sunspot activity)

•     atmospheric conditions

•     signal reflections (analogue ghosting, digital pixilates)

•     quality of the signal source (relay translator)

•     external interference (power line, radio transmitter, domestic appliances, etc)
