Do I need to buy a booster? | Installing
Sunday 29 April 2012 10:33AM

When the Rowbridge transmitter switched and increased power we could not tune into the new HD channels and had lots of picture break-up. The signal strength was about 70% and quality was about 50%. It appears that this signal strength was too high and this was causing the problems.

This is highlighted as a problem on your web-site "However, if you are not getting a good signal from your aerial, a booster by the TV set will probably not help as this will simply boost the background interference as much as the Freeview signal. In circumstances where an amplifier that has improved a picture on an analogue, it may be unsuitable for Freeview reception. Sometimes they will block one or more multiplex, where disconnecting the amplifier will restore the channels."

The simple solution was to completely remove the amplifier that I had previously used to booster the signal strength. All that was needed was a simple coaxial cable female-to-female-connector to bypass the amplifier and join the input and output cables. As a result, the signal strength decreased to 30% but the signal quality increased to 100%.

After retuning, all channels were found and we can now enjoy the benefits of watching the available HD channels.
