LP0410 is covering the right frequency band for UHF (400 MHz to 1
GHz), but it is a directional antenna. Is that what you want?
Otherwise, you might be better off using an omni antenna, preferably
on a roof...
Here are a few pointers to papers on TV white spaces:

I've posted some of the key issues on this list two years ago:

Dyspan has some nice papers on spectrum sensing as well:

Now to the setup:
Hardware / sample data
I have a USRP1, two WBX, USRP1 N210 and an PC hardware available as
well, so unless you're in a closed source / NDA environment, we
could set up a code repository on github, and I could provide you
with sample recordings from Hong Kong to cross-check detectors.
Regulatory environment / signals too look for
What is your location? From your signature, I assume you're in the
Middle East, and I guess we're talking mostly about DVB-T signals.
Is there still analog TV transmission around, wireless microphones,
...?
gnuradio packages on Ubuntu
The gnuradio packages that come with Ubuntu 10.04 are most likely a
bit outdated, so you might want to upgrade your laptops to 11.10
first.
10.04 contains 3.0.4-2ubuntu1
(
http://packages.ubuntu.com/hardy/gnuradio)
11.10 contains 3.2.2.dfsg-1ubuntu7
(
http://packages.ubuntu.com/oneiric/gnuradio)
Once you've got 11.10 with the latest packages installed, you might
want to test your setup with some of the gnuradio examples, like a
basic FM receiver to tune in a local radio station.
Hope this helps for a start - please let us/me know on the mailing
list if you need more input :)
