Im hoping someone may be able to offer some advice.
I bought a Freeview Terrestial STB. Strangely it works fine some of the time using my Rabbit ears! However, this craps out often, i realise i need to get a UHF Aerial. I got a little Draco thing but it works worse than the Rabbit ears (as in nothing is picked up by it, gutted).

I'm renting so dont want to/cant put an aerial up on the roof (thus the money i wasted on the Draco). I live on the 2nd story of a 4 story building and have a big deck. Thought i could put an aerial on the deck instead of having to try and gain roof access etc. Oh, i live in Mt Cook, Wellington.

There is a big tree at the end of the deck which blocks my view of the transmitter tower.

Will i be able to wonder down to Dick Smith or somewhere and buy the stuff i need to put one up on the deck myself and it work? If so, what are all the bits and pieces i need? How much is it going to cost me? Quite keen to learn how to put one up, but can't find anythign online giving advice on the components etc.

Any help would be amazing!
