HI. I've just installed a 91 element UHF antenna to go with my ID TV with freeview HD inbulit. When I scanned for digital channels, it only came up with 5. TV 1, 2, 6, 7, and Sports extra. On analogue, I can only get sound on Prime but no image. Can someone please help???

You have only picked up the TVNZ Mux, there are two others out there ( somewhere) the Mediaworks (Tv3/C4) and the Kordia one with everything else.

Where are you? and how far are you from the transmitter?, can you manual tune the TV if you have the frequencies?

Sounds like you might be in a hole/behind a hill somewhere,

Where are you and what transmitter are you aiming for.

I am in the Howick/pakuranga area. I am just coping where my neighbours are pointing but I beleive I am pointing either the Skytower or Waiturau. I am getting quite a clear image in digital. Do you think height is a concern as my antenna pole is really quite short.

What analog channels do you actually have satisfactory reception on?

You do really need to know what site you're aiming for. Waiatarua is horizontal polarity. Skytower and Remueua SFN are both vertical polarity. You need to ensure that your aerial is the correct polarity for the site you are aiming at.

How do I check that?

the prongs will be horizontal for horizontal, vertical for vertical.

Post a pic of the install.

Also if you have no prime picture I would be worried about the install being not connected or something, could be a stray strand shorting the cable or something.

I"ll try to get a picture but I'll give you guys an update. I tried to make it a bit higher by 1m and surprisingly, I got channels 3&4 but they were quite fuzzy. Still no image for prime.
