    Hi All,

    Wondering if anyone has any experience with clamp-on aerials https://www.powercity.ie/?par=30-72-130020
    Bought one for Newcastle Co.Wicklow and can't seem to pick anything up with it, according to the picture below I should be using an aerial in group C/D and pointing to Kippure.
    Greystones is also close and within the same group but a different polarization.
    I thought a wideband clamp-on aerial would be ok but I don't seem to pick anything up at all. Just wondering if anyone has used one? I was starting to think it's my setup/cabling but pick virtually nothing up on the signal meter directly connected so wanted to get some opinions 
    The house is a bungalow and close enough to the sea meaning it would be low enough but it's still only 22Km from Kippure. Obviously there's not much I can do in the way of moving this aerial directionally, most I can do it rotate it to the side of the dish which seems to make no difference 
    Appreciate any pointers you folks might have!

    Go for one like this.

    It is a naturally wide band log periodic. Cost about €25. You can diplex it onto the sat cable so saving running a new cable. You can then optimize its direction for best signal. You can also turn it to be either H or V depending on the preferred transmitter.

    I agree with Sam.

    That clamp on antenna is absolutely restricted in terms of direction adjustment as the dish has to be south facing for satellite reception. The rounded dipole design would offer no adjustment potential for specific direction or polarity. Is your dish on a south facing wall? if so I would reckon that the antenna you have would be useless for trying to receive from kippure with a wall or entire house in the way behind it.

    I live in Kilpedder and have an antenna similar to the one recommended by Sam pointing at Kippure with no local obstruction. I get perfect reception even though the Saorview coverage map says I should be using Greystones. I had the antenna up since before Greystones was introduced as a local option and I never had any reason to change it.

    I have also used a terrestrial antenna clamped to the mounting pole of a satellite dish where the antenna had enough space to swing around and be positioned to receive from the nearest Saorview transmitter. That may not be an option for you if the dish is mounted on a south facing wall (you may not be able to direct it backwards)

    Bottom line is you need an antenna that can be directly polarised (H or V) and specifically pointed. Depending on your exact location, you might need to direct the antenna in the opposite direction to the dish. The antenna you have can't do that and would most likely only work effectively in extremely strong local signal areas.
