I have a hershman aerial with a masthead amp and power supply which i get analog bbc and rte it is going into a sky plus box then to a loft box and then it is distributed around the house using magic eyes on channel 48 , rte is comming from carne hill.I just got a new tv with saorview it is running from loft box with a magic eye, all channels ok but no digital .Any sugestions to what the problem is

What model Saorview TV do you have?

Does the TV store analogue and digital channels serarately requiring you to select analogue or digital with the remote control?

Cairn Hill uses Ch 47 for Saorview, try moving the Sky output away from 47/48.

How many aerials do you have for the Irish and UK channels? Is you aerial pointing directly at Cairn Hill? What group is your aerial, B or Wideband?

tv brand blue diamond.Done auto tune it ran through analog then digi .Its a wideband aerial pointing at nothern ireland,all irish analog crystal clear

You probably require an aerial pointing at Cairn Hill, DTT transmits at lower power than analogue (800 kW analogue, 160 kW max for DTT). Group B aerial required.

Take note of this, OP, the Skybox modulator doesn't suppress the lower sideband of whatever channel it's using, so move its output at least 2 channels higher than any wanted broadcast.

Avoid ch 43 to 50 for Sky box. The modulators are poor.

would the masthead amp or power supply cause problems

Did you change the Skybox output channel?
