sorry if this is is a very naive post which has been probably been done to
death before ...

this old bloke i know lives in a block of flats which has a community
antenna and he is asking if they will have to replace the antenna and
cabling when HDTV becomes the norm..

from following some of the posts in this NG .. it seems that subject to
location and reception factors, the old antenna and cable would be adequate

similiarly, my readings of the posts suggest that if good clear pictures are
required than obviously changes must be made to antenna and cabling.. which
leads onto the quest... if such chgs were made NOW, can analogue tv signals
still be rec'd???

thanks very much for any advice :)

The ONLY real way to tell is plug a STB in and try it.

HD or SD makes no difference. They both use the same carrier.
(Or maybe HD is more likely to be on a UHF channel??)

Digital TV uses the same UHF and VHF bands as analogue, so assuming
the old antenna gives a good analog picture, its fine.

If the analog picture is crap, then digital might fix it, or be even
worse, due to dropouts.

Yes. Its the same underlying broadcast channels.

They do not use the same underlying broadcast channels. The digital signal
is usually sent on an adjacent channel. For example Nine Digital is
transmitted on Channel 8 and Seven Digital is transmitted on Channel 6.

I'm no expert, but I have seen posts from people who live in large apartment
buildings finding that the community TV feed has filtered out some of the
digital channels.

Yes, I mean the same set of channels. Same band. Same kind of channel,
ie 7MHz wide in the UHF and VHF bands. So same reception hardware.

This is in the context of antenna choice.

yeah.. the old "suck it and see" eh?? :)

thanks :)

ah.. so this is what other posters have meant by antenna choise .. some
older antennas cannot "see" the signal?? apologies for the rather naive use
of phrases here ...
