Channels 2-51 are all allocated to DTV (except for 37). Channels
2-6 aren't as popular so many people won't need an antenna that can
receive them; some people can even get by with UHF only (14-51). To
be sure about what you will need go to www.tvfool.com and see what
real channels will be used in your area after transition.

2, 4, 5 are very good and popular stations in the low VHF band

All active analog stations with a digital signal are broadcasting
that digital signal on a different channel. The ATSC tuners maps them
to the displayed channel number. Some 500 stations will flash cut
their digital signal back to their analog channel next February after
the analog shutdown, but the vast majority of the low VHF analog
stations will have their physical be on UHF or upper VHF.

In the San Francisco market,
KTVU-DT Fox 2 is currently on UHF 56, will move to UHF 44 next year.
KRON-DT MyN 4 is currently on UHF 57, will move to UHF 38 next year.
KPIX-DT CBS 5 is currently on UHF 29 and will stay there next year.
KGO-DT ABC 7 is currently on UHF 24, will flash cut to VHF 7 next
year.
KNTV-DT NBC 11 is on UHF 12 and will stay there next year.

The San Francisco market has perhaps the most complicated transition
of any city in the US next February and in the months afterwords,
Stations will be putting up new antennas on the Sutro Tower, taking
old ones off, moving to channels currently occupied by other analog
stations. Many stations will be using their backup reduced coverage
antennas in the daytime when the tower is being worked on.

Which, for the clueless, means NO DTV on 2-6, which is exactly what I said.

"Ch 7 thru 69 DTV"? Only 7-51 is authorized after the transition (in the
U.S.).


After February 2009, some DTV stations still will be on lower VHF (Channels 2
through 6. See
http://fjallfoss.fcc.gov/edocs_publi...C-07-138A2.pdf
Look up your city in this URL; you may find that you need a Low VHF antenna
also. For example, in Las Vegas (near where I live) NTSC Channel 3 will be on
Channel 2 broadcasting DTV.

I don't know your situation, but many folks can get away with using rabbit
ears. It works, or it doesn't. Barring a serious distance problem, a
proper antenna may not be needed.

If an antenna made exactly for DTV is cheap, then fine. However, I suspect
you may pay extra for an antenna with limited bandwidth over a close out
sale on an old fashioned 2 through 82 antenna.

I disagree on the rabbit ears. If you can do an outdoor antenna it's
preferable for many reasons like less multipath and stronger signal.

If you don't mind the size of the antenna. The Winegard 7694 is only
35" wide vs 110" for the 7082. There is no such ting as an antenna
"made exactly for DTV". Antennas cover a range of frequencies thet may
include analog or digital TV. Flatness of response and directionality
are the important issues and are equally important for analog or
digital.

However, antennas could be made for "post-transition channel allocations".
E.g. the UHF antennas tuned for 14-51, and dual-banders for 7-51. And DTV
benefits more from more directional antennas, so even those will end up
with sales people labelling them as "DTV".

Which will do no good here at all. Post transition our local ABC
affiliate is going to VHF channel 5.

There is no substitute for the long tried and tested combo vhf/uhf
antenna in our area.


I see only 1 ABC affiliate going to VHF 5 post-transition and that is
WOI-DT ABC 5 in Des Moines moving from UHF 59 to VHF 5. Is that your
local ABC affiliate? The FCC database shows WOI-DT with a low STA
(Special Temporary Authority) power of 500 Watts on UHF 59 which is a
very weak power if correct.

The good news to some extent is that WOI-DT was granted their request
to run at an increased power of 8.2 kW (up from 3.91 kW) for the
post-transition VHF 5 allotment which is a good power level for digital
low VHF. In Des Moines, IA, there should be a number of open channels to
broadcast on UHF if WIO wanted to.

Dear Bob W4NNG: I have been using a Winegard HD-1080. Reflectors behind
two, parallel, broadside UHF fan dipoles that each have an extension to help
with 7-13. I an using it with 12 and a bunch of UHF channels and it does
behave as expected. I would not call it "high-gain," but good enough in
this flat area.

73, Mac N8TT
