Have picked up my CM4221 at TSB in Point Roberts WA (a.k.a. Tsawassen BC) - Amazon delivers free, but doesn't sell to Canada. No biggie, 40 minutes drive.
Hate investing in electronics (it's endless), but this $45 was one of my best investments. Bright box like a toy, acronym HD and HDTV is mentioned 7 times on it - like this has something to do with antenna
My location at Clark/Broadway is terrible. 2nd floor South balcony, 10 miles to Mt Seymour but North direction is blocked by my building stucco wall. To the South I have 4-storey wooden building 60 ft away and then other buildings, and terrain ascends from me to East 33rd Ave before descending to Marine Dr and New West, so there is no LOS to Bellingham. All I have is reflected signals.
Positions tried (removed plastic clips and reversed balun, see "4221 Hack" thread):
1) Best position:
Antenna 1 ft from the deck, azimuth South-East 160 deg, boom slightly tilted back/down (i.e. antenna facing slightly up to Southern skies). Strictly plumb is worse - it doesn't clear some obstructions.
2) Antenna at the railings, facing North to the stucco wall 5 ft away. Slightly worse than #1.
3) Antenna outside
the balcony railings, facing South. In theory, this should've been the best, but... When simply hung vertical on the railings it's not good. It has to be aimed a little up and turned 20 deg to the side, which requires complicated boom extending beyond the railings, so I dismissed this option.
Analog: 2, 8, 17, 26 (French), 32, 42. Signals without picture, some remote mirrors: 9 (mirror of 8), 10, 18 (mirror of 17), 43 (mirror of 42).
Digital: 2.1, 8.1, 10.1, 32.1, 42.1 with signal 50%-70% on a dry day on all channels except 42.1 (this one is always strong). If I make some channels 80%, others drop below 50%, so I've opted to have them all in 50-70 (except for 42.1 again, which is always blasting over 70%).
According to TV Fool, I should have the above channels with indoor antenna in ideal location (nothing blocking LOS). Can't complain, since my location is anything but ideal - I have no LOS to anything.
