TV aerial doubled up

[Phillcbr400]

Just been given a brand new high gain aerial. I've already got the exact same version on my roof. Can I put this new one in the loft and join them Together? Can't seem to find any splitter which have 2x inputs too 1 output. Or will this be a wasted effort and not do much?

about as useful as a lifeboat on a submarine. just keep it as a spare or use it to feed a TV in anither room.

Haha cheers tel, Just thought it could possibly boost the reception, all the tv's will be fed off the roof aerial anyway and ill have no need for any more ports in the house.
