Unfortunately yes. The DVB-S cable is likely connected to a satellite
dish. The satellite dish will not receive DVB-T signals. So unless
they have used some weird way of multiplexing DVB-T and DVB-S on the
same cable, that ain't gonna work.

Very much a case by case thing. Freeviewnz.tv has a system where you
put in your address and it tells you where your signal should come
from. At least then with google maps or something you might get an
idea of which direction to look in! If it is Auckaland I believe they
transmit from SkyTower - do you have a line of sight to it? If you can
see it out your window, you should try an indoor antenna.

Auckland, as you guessed, but I thought the question might apply to
cities in general.

I had imagined some sort of weird multiplexing, yes. I have a friend who
recently had an antenna guy sort his stuff out for him, and both signals
arrive in the house on a single coax. There is a splitter inside, but I
don't know if it has any filtering in it.

I also recall my landlord saying a previous tenant used to get analog TV
here, via the same old coax. I doubt their capacity to understand though.

I can not see the SkyTower, but the top of my building may. If you see
what I mean.

I see DSE sells an adaptor/flylead for an outrageous price. Maybe I
should simply fork out $20 and suck it and see.

Try Jaycar if you have them in Auckland, or any TV aerial installer or
service company. Or buy them online.

This is certainly possible.

A diplexer, such as
http://www.supremeantennas.co.nz/view/baluns-diplexers-combiners/diplexers/diplexer-tv-to-sat40-860-950-2300mhz.php
(first one that came up in search) is used. One at the antenna end to
combine the uhf / terrestrial signal below ~860MHz and the satellite
above ~950MHz onto the same coax cable, then another diplexer at the
receiver end to split them again.

Whether your apartment building is setup like this is unknown, but it
can be done.

If you're in Christchurch/Canterbury I can recommend an excellent aerial
installer.

Hi,

It's definitely possible. I used to live in an apartment that hand
only one coax, I used a splitter to feed a DVB-S and DVB-T cards from
it. Worked very well.

kind regards
