TV signal strength discrepancy
 

Why would there be such a difference in signal strength that I receive
for these two channels?
They are both broadcasting from the CN Tower in Toronto and they both
have close to the same power output. The CTV signal is always 99% or
100% on my TV while I can barely get 50% most of the time for CBC yet
the CBC signal is twice as powerful. BTW, the tower is south of me and
I am facing north so I know that will have an impact. Just not sure why
it would have more of an impact for one and not the other.

CTV - 17.4 kW - Channel 9.1

CBC - 38 kW - Channel 5.1

Another thing. If so many people now get their analog signals from
cable, why don't the broadcaster switch and put their HD on the more
powerful transmitters. For instance, CTV's analog transmitter is 316kW
with two repeater stations out in the sticks. CBC's analog transmitter
is 100 kW. It also has many repeater stations.

These are pseudo channels. What are the RF channel numbers?

20-1 for CBC and 40-1 for CTV according to a website I am referencing.
My ATSC tuner says they are on 5.001 and 9.001. Why are they pseudo
channels?
Does this mean they are being broadcast as UHF channels and mapped to
5.001 and 9.001.
Do I have to adjust the UHF part of my antenna to get them when I was
adjusting my VHF antenna, thinking they were VHF channels?

Yes. the displayed channel number is carried in the 'PSID' (Program
Source ID) and is not related to the RF carrier frequency.

adjusting my VHF antenna, thinking they were VHF channels?

Most likely. There are a few broadcasters using VHF carriers and some
may move back to their VHF frequencies after the analog broadcasts are
terminated. But for now, most broadcasters are using the UHF band.

OK, so I gave you the frequency. Does that tell you anything about why
one signal is so much stonger than the other?

I would suspect it's Rayleigh multipath fading - move your antenna and see
what happens

Not me. You're the one with the antenna(s), location, and direction to
the transmitting towers.

Maybe a visit to http://antennaweb.org/ would help you determine the
facts you need.

So then, why did you ask me what the RF channel numbers were? Just
curious?
