    Yes, the H or V question is sorted at installation time, the product is the same regardless.

    Any reason why you can't use an indoor/set-top antenna? Using an outdoor one sounds like a touch of overkill...

    :confused: Overkill? How do you know? Or indeed could it ever be considered overkill to install something better than a set-top aerial?

    If there isn't an existing pole in place, the OP will require a new one, a mounting bracket and sufficient coax to connect to whatever points are required if he uses an external antenna.

    Why spend more than you have to, and involve yourself in climbing onto a roof or other hazardous location when quite often it's not really necessary?

    If an external antenna isn't necessary to obtain a perfect picture, then doing so is really a waste of time, money and effort. That's what you call overkill.

    Quite often it's possible to receive a perfect picture without resorting to erecting an external antenna, no matter how small. It just seems prudent that he might try something internal first to see if it's possible to get decent reception before he invests his hard-earned and risks life and limb...

    If the OP has a dish, it is easy to install an aerial close by and use a combiner to send the signal down the existing cable. At the TV another one is used to separate the two signals. The only difficulty would be if an amplifier was needed.

    It would be preferable to run a separate cable for terrestrial if possible. Sat/Terr combiners introduce loss and may well make the difference between stable terrestrial or prone to breakup!

    The outdoor combiner is also another weak link in the chain that could fail in the future after a lot of extreme weather.

    Not my experience at all. If the OP can get any usable signal from an internal aerial, then there will be plenty of signal from an external aerial. Obviously an external device needs proper protection, but LNBs are available that incorporate a
    combiner, so no problems there.

    The saving on cabling makes such an approach compelling.

    It may be easy for you to install an aerial close by but by the sounds of it,the OP isn't experienced with antennae and satellite dishes....

    It might be interesting to hear how far the OP is from the transmitter and whether there is line of sight to it....AFAIK the Greystones transmitter is 0.5kw.

    I am not an installer but I did install my setup. However, the OP could pay someone if it is beyond his/her abilities.
