Why in Londonderry we only receive a few channels, we do not get things such as Dave etc. even RTE cannot be seen, it comes up then a thing comes on screen saying Not Supported?
Are we likely to receive all the freeview channels on offer in this area or are we to forever have this substandard service. For licence fee payers it is not acceptable coming into 2018!!

BRIAN QUINN: because Dave etc are commercial channels, and your on a Light transmitter - they just dont think its worth broadcasting to you.

The only way you can receive the full Freeview line up is trying to pick up Limavady transmitter which transmits them all. Freeview think that since Limavady is close to Londonderry, it should be reasonable for most of the city to pick up Limavady.
