Default Would a discone cover all the US TV broadcast Freqs?

I want to put up the smallest outdoor antenna that would cover all TV
Broadcast Freqs being used after Feb 2009. The log-periodicals are too
"un-stealthy" to go unnoticed by the XYL, but I think a little discone with
some black paint might escape her inspection as long as I do the
installation while she's out shopping.
Question is - have any of you used one for TV - and if so, how did it
perform? would it cover the TV broadcast freqs ? (I'm aware of its lack
of gain - I'm within 5 miles of most local stations, and within 20 miles
of a couple more.)
Thanks

It probably won't take too much antenna of anykind to get the digital
signals. I bought a converter for an old set and hooked it to a 432 antenna
about 20 feet off the ground and got about 20 stations. Then hooked it to
a M2 9 element 2 meter horizontal beam at 60 feet and got 29 stations on
autotune. I am probably 20 miles or more from the nearest station . More
like 30 or 40 miles from most.

Why not just put a normal antenna up in the garage or the attic? A small
yagi should do it. You can remove the UHF reflectors if there is plenty of
signal. Even cut half of the UHF directors without much loss. Bring it up
in the rafters and spread it out. Not near as good as on the roof but you
can always put it up normally when she finds out about it anyway.

That last sentence is the point here. She'll find out anyhow.

Hal, it might be time for the "talk". My XYL hates antennas. When I
wanted to put up my dipole and vertical, she groused a lot about it. My
reply was that I keep the yard beautiful, put in lots of landscaping,
and a pond. Now I would like to have a couple antennas for my hobby that
are pretty unobtrusive. Maybe I'm in the wrong hobby? Maybe I should
take up going out to bars, and hanging out with loose women. At least
with radio, you know where I am every night.

The antennas went up.

Amen brothers. If not for decent women and antenna arguments, we'd all

You are aware that many of the DTV signal are UHF band? Right?

This:
"Are DTV signals broadcast on special frequencies?

No. DTV broadcasts use exactly the same channels as regular analog
television. While many DTV stations are now occupying UHF broadcast
channels, broadcasters are allowed to move back to their original VHF or
UHF TV channel once the transition to DTV is complete.

The only caveat is that TV channels 51 through 69 will be auctioned off
for other uses at the end of the transition to digital TV. Stations who
originally had analog channels in this band will have to move, no matter
what.

One potential problem with re-using low VHF (2-6) TV channels for DTV is
the possibility of interference from other signals during certain times
of the year. "Skip" may bring in distant broadcasts on the same channel
and create interference. Impulse noise is also a problem on low VHF
channels. What’s more, the physical size of low VHF and high VHF
antennas is much larger than that of a UHF antenna.

Tests so far seem to indicate that high VHF channels (7-13) are quite
well suited for DTV broadcasts, and many broadcasters plan to move back
to their high VHF channels at the end of the transition. VHF
transmitters also cost much less money to operate than UHF transmitters."
