Receive DVB-T transmission with scantenna?

[synoptica]

Hey all,

Sorry if this isn't the right place for this question!

I'm looking at picking a cheap(ish) discone scantenna that covers 25 - 1300 MHz.

I live on the bottom floor of an apartment building; I have roof access, but I don't want to have to run an additional cable.  As far as I can tell, each unit has its own antenna (it's a pretty old place.)

Being in St. Kilda and in a 3-storey building, I have LOS to both Mt. Dandenong and the repeater in South Yarra.

To avoid running an additional cable, I'd like to utilise the existing TV cable, and disconnect the current VHF/UHF Yagi.

So, am I likely to be able to receive DVB-T transmissions without a directional antenna?

Any advice appreciated!

Nobody can anwer that for you, try it is the only way to be sure.

It depends on:

- transmit power
- transmit antenna gain
- path loss
- cable loss
- receiver sensivity
- ...

That's fair.  I was more after a "nope not suitable" or "yes, potentially" sort of an answer, but of course there's dozens of factors at play.

My understanding is that Yagi antennas are the common TV antenna design to reduce ghosting, which makes sense; but I'm not sure if this will less/more of a factor with DVB-T.

Anyway - thanks for your input!

How about an IP based System? I have the same Problem. TV Dish on the Attic and I live in the Basement. So i desisted to use an "TV Server" who is an old IBM with 3 TV Cards in who record the TV Channels I want.

You can make a  broadband "Planar Disk Antenna" out of two pizza plates - cost = almost nothing.
