Interference with an indoor aerial with sky q box

[Chris602]

We  ve just bought an indoor tv aerial for a tv which doesn't have sky q available to it so it needs it for terrestrial tv channels but when we switch on that tv it knocks the sky q box off in the living room ! Does anyone know if there's an aerial that will work with said tv but not interfere with sky q please ?

What does 'knocks the Sky Q box off' mean?  (IF that's the box with satellite feeds then an RF signal from an aerial would not interfere)

It's all sorted now we ve figured it out it was a switch on the indoor aerial
