We have a new house build at Kaukapakapa and the builders have put in all the relevant tv wiring to some rooms, so i'm just wondering how easy it is to whack a UHF aerial into the attic/rood space?


The cables come through to a junction box in the garage where I assume I have to connect a splitter from the attic cables, to pass the signal to the rooms?


Not quite sure what size and type of UHF aerial to get? Does it have to be orientated vertically/horizontally - or makes no difference? Unsure. Pointed towards city or waitak ranges?


Assume also I just get some screw on connectors for the cable ends in the attic and then these connect to the aerial box?


Happy to give it a DIY go, just need some advice. Thanks guys.




(OR whether to get an expert in, as we need one for the main and one for the minor dwelling....)

First try the Freeview coverage check tool


Also Matchmaster have an antenna selection guide


You're probably going to need a professional roof install unless you're reasonably high up.

I never had any luck in the roof space myself but setting it up on the roof was easy enough, have a look at what some near by houses have because you can get phased array or yagi antennas, you'll see the neighbours will mostly have one type that works the best based on location 


For getting it up I used a combination of google earth and good maps for pointing in the right direction.


My cousin just built a place out in Kaukapakap and the builders put the antenna on the roof but didnt align it - he's not really into giving that stuff ago like myself so he got a tv guy out and it only cost him $60 so it's relatively in expensive

Thanks both for the info. I asked the other street residents a while back and most said they had something in the roof space (noting its also a high wind zone) which seemed to be doing the job. Next time im at the property I'll check all the roofs again for aerials (as that was my first thought). Its a fairly elevated section near the church so will see. Thanks for the tips.




Coverage map said use a roof mounted aerial, but the more detailed map shows green for the street which is the normal signal strength it seems.

What's your roof made out of? If it's iron, you will get a very poor signal in the roof space.
