See if you can find an available channel for WDTV, then (ironic callsign).

Most markets in the USA have to deal with issues from stations in all directions
around those cities. Los Angeles doesn't have to deal with stations to the west.

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".

I plan on not using those anymore at that time. other wise works
good for analog, digital TV and radio.


oops guess i wuz wrong I see a couple in my potenetial area on DTV
channel 6. May be a good thing to have the full antenna after all.

FOUND ANOTHER ON DTV 4 CBS. dude don't be leaving out channels by
getting the wrong antenna. could be sporting events from different
cities and states you'll be missing out on if you don't get low vhf.

Besides Wineguard's HD769 series, anyone know of other Ch 7 thru 69 DTV
hi-gain outdoor antennas?

Im using this one for last year or so.

no complaints. survived some good storms too.




That is NOT a safe bet, depending on your local stations. Two of our
local stations will be reverting BACK to VHF at that time. They are on
UHF now. So before telling someone that they will not need the "longer
elements" (VHF), it would behoove them to check and see just what their
local conditions will dictate.

Our local ABC affiliate WOI is reverting from UHF to VHF channel 5 in
Feb 2009. It's nuts, but that's what they are doing. Nother station is
going from UHF channel 31 to VHF channel 8...so it is NOT unheard of and
those who blindly go UHF only in an antenna without knowing what EXACTLY
their locals are going to do may find another antenna purchase in their
future.

Usuaully its the stations the FCC did a screw-job on.
They already had
low-band analog and were given either a low-band
transition or a depricated
UHF transition in 52-69.

Congress should have mandated that the FCC find space on
high VHF or UHF for
all stations that wanted it, with an emphasis on making a
market have all on
UHF where possible, and where not possible, put many on
high VHF so that not
a single station is alone there.


Phil,

Some stations wanted to remain on the low VHF channels for
power and propagation reasons. Some broadcasters in the
Midwest with large coverage areas get a lower electric bill
on those channels even though the threat of interference is
higher. Interference is a bigger problem in metropolitan
areas than it is in the flat rural corn fields of the U.S.
bread basket.

I used to work at a low band VHF station that was running 56 kW ERP.
The actual transmitter output was 8kW visual and 2.3 kW aural. When I
bellyached that KABC 7 in LA would be running only 13kW DT, Alan
Figgatt pointed out that DTV doesn't require as much power as analog
and 13 kW should be good here. The point is that from a power
standpoint, VHF-lo vs VHF-hi wouldn't be all that big a deal. The
station gear and A/C would be a much bigger load than the actual
transmitter. Compare that to analog UHF where 55 kW visual and 10kW
aural is common. THOSE folks will see a big savings but compared to
the power load when all the studio lights are on for a production or
newcast, even 65 kW is a big part but not the biggest. HVAC can be a
bigger load issue - particularly with VHF-hi where 13kW ERP may only
need a few kW of acutal transmitter output.

I hope I don't hear how the DTV breaks up a lot during lightning
strikes. I know that on VHF-lo analog you get LOTS of 'sparklies'
during lightning storms.
