Hi guys,

not sure if this post is in the correct place.

I am rewiring my entire house and have decided to redo all the communication and tv etc too.

Do you need VHF/UHF anymore?

Do TV's with freeview use satelite or UHF/VHF?

Basically I want to know if I can do away with the old aerial and just install a dish for everything

Any help much appreciated

Freeview|HD is UHF. Regular Freeview (non HD) is via satellite.

The question depends entirely where you are located and whether you want HD programming or not. The preference should certainly be for Freeview|HD is you are in the current 75% of the population who can pick this up.

You might also like to look at the newly updated TCF Premises Wiring guidelines. These should form the minimum spec for any work you perform

Thanks guys,

I am in Onehunga, Auck

My next question is, can the 2 signals be linked into one wire or both must remain separate?

You mean satellite and UHF? Yes they can - but only with a single LNB and a single aerial. Running fewer cables isn't ideal. The new TCF guidelines recommend 4 cables to the master TV, if you ever go with MySky you're going to need two cables anyway as this is now the norm.

Thanks, I am only new to communication

I will read the document.

I have no issue with feeding more wires in the future.

Just quickly I have

Lounge: Sky (normal)

Bed1: freeview

Bed2: freeview

What is your wiring suggestion?

Quick guideline.

TV's with 'built-in' Freeview will only work with a UHF aerial.
This will give you up to 'HD Ready' quality.
These TV's will not give you a Freeview signal if you're using a satellite UNLESS you attach a separate Freeview Satellite box.

If you choose to run with a Freeview Satellite box, the signal will only ever be as good as standard definition. This may be okay in the bedrooms as the TV's will most likely be small, so that high resolution won't be as critical. But for the lounge, I'd try to get the highest quality signal, as the TV will most likely be bigger. Your best option there is a UHF aerial to give you HD Ready Freeview or a Satellite dish to get Sky HDi.

As a caveat - you cannot record off a TV with 'built in Freeview' as they don't have a 'picture out' port, (or a scaller / second tuner). Some new TV's do allow you to record free to air TV onto a computer hard drive though... but then only allow you to play the shows back on the TV you recorded it on, not another TV / your computer).

My pick, Sky HD in the lounge, with a UHF aerial in the bedrooms running through TV's with built-in Freeview, as you're then covered for the days when your Sky satellite dish suffers from rain fade.

Forget freeview sat - even on a 21" CRT with letterboxing the starvation for bitrate is obvious.

TVNZ and mediaworks clearly dont give a crap about the 20% of the country outof the range of terrestrial HD by delivering the low bitrate junk that they do.

hi guys, thanks for reply

I have read the TCF doc and all is clear as day

Is there any need for a VHF for future, if not, that ugly arrangement of sticks is coming down

Many thanks
Ian

Hi, no there is no planned broadcast TV in the VHF band post analog shut down, so pull them down and use them as tomato plant suspenders.

Sorry thats incorrect, the NZ standards adhere to the DVB organisations norms, which state anything that is 720veritcal lines or more is HD and a display capable of that is determined as HDready.

It is our Aussie cousins that convinced their pollies to allow the substandard 576p to be termed HD.

TV3 like other broadcasters throughout the word use either 1080i or 720p as their HD broadcast standard and naturally have little choice but to upscale any SD material they output.
