This might be a bit of a newbie question but I have 2 dishes Sky & TV Cabo but only one cable going to apartment. I would normally just swop over cables in the loft to whatever the person renting the apartment requires and was thinking of installing a changeover switch

Switch Switch for BK and SAT Systems F Socket - 2 x F Socket (1 Switch) : Amazon.co.uk: Electronics & Photo

but was wondering if i am better using a splitter or another way or will it not work having both dishes connected to one receiver simultaneously?

thanks in advance. Japn
