Not sure why my reply from yesterday wasn't posted, but anyway:
I have an exclusive use of the balcony but I do not own it. I think we don't even own outside of the doors. It would probably be OK unless someone complaints, but I do not want to end up with $100 antenna that I can't use.
After playing with TV settings (I had to set cable to "OFF"), I got 31 digital and a few "white" analog channels.
Would ClearStream2V antenna help me get the missing channels?

It looks like I'm missing mostly analog channels
Analog
CBLT 5
CFMT-TV 47
CIII-TV 41 (not sure if digital CIII-TV is the same - 41.1)
CJMT-TV 69
CITY-TV 57
CITS-TV 36 (altough it is at 202 degrees, so may be difficult to get)
CKVR-TV 3 (altough it is at 350 degrees, so may be difficult to get)
CIII-TV 6 (altough it is at 240 degrees, so may be difficult to get)
CKCO-TV 13 (altough it is at 254 degrees, so may be difficult to get)
CIII-TV 27 (not sure if digital CIII-TV is the same - 41.1)
WBNF-CA 15 (it is 52 miles away)
Digital
CITY-DT 44.1
CJMT-DT 44.1 (two channels fighting for one spot?)
CFMT-DT 64.1
CKXT-DT 66.1
CKXT-DT 15.1 (not a typo, same name as 66.1)
WNYO-DT 49 (no .1? strange)
WBBZ-TV 67.1 (tvfool's chart says path - 2Edge, which is kinda strange at 151 degree angle)
I do not get any of "Grey: These channels are very weak and will most likely require extreme measures to try and pick them up". Whatever is between 180 and 360 degrees has to go through the building; so I do not really expect to pick that up.
Other channels that I'm missing from here:
http://www.remotecentral.com/hdtv/index.html
This TV 67-2
METV 67-3 (don't care, as I get it in 720p/2.0)
Daystar Television Network 67-4
WUTV-DT 29-1
Supposed to be far/hard to receive - about 10 stations out of Rochester.
