should this aerial be ok?

Hi folks,

Have to buy and install an aerial for a friend to get the irish channels on (already installed a freesat system). I reckon this aerial should do the trick nicely? I'm in the ashbourne are so judging by the covers maps on irish-tv.com i should be able to get Clermont Cairn and Three Rock pretty easily!

I realise there might be cheaper alternatives but theres an argos only up the road!

Thanks in advance for any advice!

Are we talking DTT reception or not? Clermount Cairn and Three Rock you mention make me think you maybe.

Thanks for the swift reply foggy.

No i'm not talking about DTT, just plain old analogue for the 4 irish stations. Only looking to feed one tv from the aerial at the moment as well. thanks.

Digital & Analogue is no issue, aerials are aerials. It just a matter of the correct group.
Note that group W or "wideband" versions of the any big aerial are really best on B/C groups and progressive poorer on A (as frequency lower) and on D as frequency higher. They can be as much as 3dB lower at top of Group C

That aerial is not a high gain type so is wider band than higher gain models. The large reflector is always good.

Its hugely better than any set-top or amplified aerial rubbish.

cheers watty...i think i'll give it a go. Just to clarify something...u said its better than any amplified aerial...did you mean just indoor amplified aerials or outdoor aerials with an amp as well?

Thanks,

Kevin

The amp 1m below the aerial is only to overcome loss on the downlead. The gain should equal downlead attenuation. Unless you are in weak reception or a very long downlead you don't need an amp.

Note some places the 900MHz can overload an amp but a TV/Sat diplexer (about 5 Euro) with 75 Ohm terminator on the Sat port will greatly reduce the intermodulation if between aerial (common) and amp (TV port).

Indoor amplified aerials are pointless as there is little connection lead, TVs are sensitive enough and you will just amplify noise as much as signal. Maybe if it is in an attic with 50m of coax to tv...

should this aerial be ok?
