I've not had any problems with the UHF circular loop that comes with
standard rabbit ears. The only problem I've had is with VHF channels on
the dipole. I need a weatherproof version of my RS rabbit ears.
Unfortunately, ABC is Channel 7 here in Tyler, TX.


Where I'm sitting here in Whittier, KABC 7 is so strong I can get it
without even a cable plugged in!

It's 50, 56, and 58 I worry about; 2-13 and 28 are covered; I'm looking
forward to seeing if my new bowtie (from that youtube video, but with
ER708-2 x 1/16 filler rod) will pick up PAX on 30. They have some nice
oldies sometimes. (I also have some of the ER708-2 in 0.045".)

I'm gonna solder it together and hold it to the board with brass thumb-
tacks. ;-)

Decent power, line of sight (18.2 miles @ 172.2 deg true) will do
that.

Ion TV 30 is in Claremont and has a 3.8 Megawatt Signal (elliptically
polarized no less). It should give you a tan in Whittier.

Frequency re-allocations were mentioned up the thread in


I'm surprized no one has mentioned http://www.tvfool.com

Here's what you can expect to get in one part of Whittier
with a 20' mast:
http://www.tvfool.com/?option=com_wr...d%3dea7348065e
(The results are a graphical representation of the data
so it's not searchable with a text search utility.) 8-(

Here's the version that isn't scrunched into the middle of the screen:
(Right-click; Show only this frame)
http://www.tvfool.com/modeling/?id=ea7348065e
(Your exact zip code and elevation may give different results.)

The lowest commercial channel you will get is the
faith-healer/preachy-movie channel reallocated from 40 to 23.

The *all will move below 52* statement in Platt's wasn't accurate.
While KDOC56 will move to 32, KLCS58 will move to 41,
and KOCE50 will move to 48,
**KCOP13 will move to 66 and KCET28 will move to 59**.

Careful. The channels you mention as "will move" are already operating
digital
on the "will move to" channels. Some will stay where they are.

At Transition, the four LA stations on analog VHF-HI channels, 7, 9, 11 and
13, will secure their digital UHF transmitters and initiate digital
transmissions on their historic (analog) channels.

After Transition, no so-called "regular TV" will be on channels 52 and
above. Other services have won bids for those channels. Qualcomm has
channel 55 for MediFLO mobile TV, etc.

Pls see http://www.rabbitears.info/dtr.php and scroll downpage past New York
to Los Angeles (they're in market-size order). See the fourth, fifth and
sixth columns for each station's FCC assignments: analog, interim digital
and final digital. It's all there.

I hope this helps.
