Lately we have noticed the majority of new TV Antenna Installers and Electricians are using cheap hand held TV Signal Meters as some of them can be up to 20 times cheaper than professional TV analysers, and due to their lack of experience and not knowing the down side of these meters can lead to unnecessary call backs.
The first and most important function used when doing an analysis of the digital TV signal is the spectrum Analyser, and because of the slow sweep speeds, low resolution and limited frequency range of cheap hand held Analysers, this makes it impossible to see any potential problems that may develop in time.
The limited Frequency Range of up to 860MHz means we are unable to measure mobile phone frequencies above 870MHz or any other potential issues at the higher frequency range, doing Installations without making checks at these higher frequencies would be guessing and could lead to potential issues in the future.
North Coast TV & Antenna Service only use Professional Digital Field Strength Meters for all TV Antenna Installations and TV Reception Repairs. We use proven technology that’s fast and does a thorough Signal Analysis of the Digital TV Signal as this will guarantee the future reliability of your TV Reception.
If an Installer shows up at your door with one of these instruments it is highly likely they are not Professional TV Antenna Installers and most probably an Apprentice, Electrician or an I.T Guy. If they do the job you should ask for a guarantee in writing, that if the same problem starts again in 3 to 6 weeks they will come back and fix it at no charge.
