UK - MA2500D

HI,

I'm in the UK and am looking to replace a pair of PowerLine adaptors with these but have a couple of questions.

1. Is there any way I can tell if the amplifier \ splitter that I have in my loft will work with these?

2. The coax in my house is used for standard UK TV through an aerial. Will it work alongside that, or will I need a filter?

Thanks
