That looks about right. I am not trying to get KOAC Corvallis,
since I have KOPB on 10 NTSC & 27 ATSC.
> you mention analog channels. you have analog ch 2,6,7,8,10,12
> in the mix. ch6??? the ya 1713 is not used for ch 2 or 6.
Yes, I know that the YA-1713 is VHF-HI. Our VHF-LO stations
are supposed to go away in 2009 and the YA-1713 has better
specs than a VHF 2-13 antenna.
The YA-1713 does okay on VHF-LO, not as good as on VHF-HI
but good enough to get by for a couple years. Even the low
power channel 4 comes in pretty well. If I only split 4 ways
channel 4 is still reported as 100% signal strength from
the digital tuner, with signal quality of 75%. Sometimes
it is received perfectly, although usually it drops a few
packets per hour. Channel 4 is supposed to move to channel 22
> But in 2009 you are only going to need uhf.
8 10 and 12 are currently analog, but will become digital in
2009. The VHF-LO analogs (2,5,6) go away in 2009. Channel 4
moves to channel 22 in 2009. So I will need VHF-HI and UHF.
So I bought the YA-1713 and PR
> move the antenna outside
Yes, I would probably get a better signal with the antennas
outside... until the next wind storm. High gain antennas
less than 5 miles from the towers looking through wood ought
to work okay. And for some stations they do. I chose highly
directional antennas to reduce multipath.

Adding the 1st 95-108 trap helped. Adding the second one
helped more. Adding the 88-108 trap knocked KBVM 88.3 FM
down enough that I can listen to the audio on channel 6 NTSC
without having KBVM superimposed on top of it. Adding
the ferrite sleeves appears to have reduced common mode FM
that messed up the picture on chan 10 NTSC. Like this:http://www.kyes.com/antenna/interfer...nofmfilter.jpg
The most problematic station is 33, it is 750 KW and is supposed
to remain at channel 33 after 2009. It usually drops packets and
always has decoding errors. The Cascade2 demodulator reports
100% signal strength and 95% signal quality. This is the best
reported signal quality of any station, but it has the worst
actual reception. (Actual reception meaning decoding errors.)
The reported signal quality does change with signal level.
If 33's signal strength is reduced to 75%, quality goes down to 55.
As opposed to channel 27 which reports a quality of 55-65%
regardless of signal strength.
