    I understand you can get aerials that are designed to reduce ghosting on analogue pictures.

    Can anyone recomend one or comment on the best way to reduce ghosting?

    Ghosting is simply your TV receiving a signal from multiple sources - this could be multiple transmitters, signals bouncing from another building (or even trees, another aerial in the way etc) or more then likely a badly setup aerial in the first place.

    If it's a rooftop aerial - then get an aerial company to re-set it up (worth changing it for a higher gain aerial if you thinking digital TV btw) - if it's an indoor aerial - then try moving it away from metal objects and walls to see if that improves things. Boosters will NOT remove the Ghost - they will make it worse ...

    Cheers Teeerex.

    It is a rooftop aerial but living in central London makes it virtually impossible to consistently avoid reflected singals. I've heard of aerials that have a special design to eliminate these reflections but it sounds dubious so was hoping someone out their has used one with good results.

    Note, I'm planning on installing/repairing this myself which is why I'm after the advice before risking my neck :rolleyes:

    The antenna type known as a "log periodic" does have better multipath immunity than the standard yagi antenna.

    A decent aerial rigger should know this already.
    You can Google for "log periodic" to find more information.
