DTT In Naas

mjsmyth

Morning all, I am just back from the UK where I picked up a cheap Tecnnosonic STB 2008 receiver.

I got to pay a visit to b&q to buy an aerial this weekend. What type should I go for? It is going to be placed in the attic. Is bigger always better?

Has anyone around the Naas area tried DTT yet? The aerial will not go to waste as my tv reception with small set top aerial is crap.

Are these aerials any good?

Which one should I go for. As I said, even if the STB does not work, the aerial will not be wasted.

Thanks,

My opinions about picking it up in Naas haven't changed since this post. I don't think we have seen a report from Naas, and really, its at best marginal. As I said there, a condition of getting DTT is getting either transmitter with analogue in the first place, and at that, its not a done deal.

Tell us what stations and on what channels can you get the analogue stations on? Even with the ropey bunny ears.

(And the 48-element over the 18)

I shall check when I get home tonight with regards to the channels and the bunny ears!

I notice that the TV in the bedroom gets exceptional quality for the 4 terrestrial channels when using the bunnies. The TV in the sitting room does not, using in the same bunnies.

I also need to find the right direction to point it!!

For Naas a giant BBC pole with vertical C/D group for Clarmont Carn added. Three rock is impossible there. But I CAN pickup and work the Dundalk 145MHz repeater (same TX site I think) of and on all the way from Kildare to M50, Mobile.

As said before I lose the Three Rock repeater leaving Dublin on N7 passing the Rathcool Service Station (a few km before Kill turnoff). This is somwhat past the Rathcool junction leaving Dublin.

When Brougher goes to high power instead of 200W to 400W at present in 2012, it may be good as I get the West Tyrone repeater intermittantly from Dundalk, N2, to M50, to N7 as far as the Western side of Roscrea.

Hi Watty,

What is a "a giant BBC pole with vertical C/D group for Clarmont Carn added" ??? I have a feeling I wont like the answer

As for 3 Rock, is it a power issue that stops Naas receving from it or something else. some parts of the town have a good view of the Dublin Mountains.

Its geography.

This map from Richie's site for analogue Three Rock. If you look closely at the N7 road, you will notice that its more green and blue for fringe coverage, the more you turn 90° past. You will see more of Kippure than Three Rock from Naas. If you look at where the N7 placename is on that map, thats roughly where Naas is on that map, and it is fringe at best.

Google Earth file which plots the sites of Three Rock and Kippure, and the associated topography.

Fair enough, does anyone have a spare digger and a few sapre hours, I just want to shorten Kippure....

As you go out the Naas road the masts for BBC/Claremont are about Chimney Height at Red Cow (yes some appear to be vertical C/D so they must be in back spots for Three Rock/Kippure). Others are massive Quad Group A/B for Divis /Belfast (Horizontal).

By the the time you are actually passing Naas the masts must be nearly 90ft.
They get bigger and bigger and suddenly vanish as you head toward Portloise.

You are looking at different hils or the backs of hills that the Three Rock aerials are on.

Hi Watty,

Yeah, I looked at google earth and used the terrain option. It appears, as stated above, that Kippure is in the way

You can buy quite good lattice masts for 1200 Euro. Or 45 ft pump up from £400. For Clarmont Carn and Divis

mjsmyth

I think I shall hold off on buying those!
