I recently put up an antenna, I live in North Waterloo.

I am having a problem getting any of the digital channels.

For analog channels I get
I can get CKCOTV (13) as if they were broadcasting in
my room,
I get CityTV2 (31), CHCHTV (11), CIIITV (6), CBLNTV1
(56), CICOTV28 (28), CBLFT8 (61) and somehow CFPLTV (10)

According to TvFool.com I should be getting a number of
digital channels as well,
especially ones like CIII-TV (6.1), CKCO-TV (13.1)

I am in an apartment facing south, is digital require
better LOS? I figure the proximity to these stations should
totally allow me to receive that channel.

I should mention that my TV does have the ability to tune
digital channels.
I have a Sharp (LC-46D62U),
It has a Setup Digital Antenna part in the menu which
is greyed out until it detects a digital signal.
