I used a temporary 3" aerial off a dtt usb stick but will be replacing it with a better amplified one as my rte1 hd sucks and rte2 hd works.Not far from a transmitter .This was an add on sat dish aerial and combiner running one feed down one cable and other combiner to split to sat and aerial splitter.I was told i needed a better product as i still had my triax aerial and to use that instead.
