Today I was at my station during two complete overhead AO-16 passes. I run 45w to a vertical 19" whip. The morning pass less than 6 degree elevation over the atlantic I got 0 packets through. (As expected due to my vertical and PACSAT's perpendicular approx horizontal whip and path of 1600 to 1800 mi. The overhead pass, I began getting very good success (6) above about 20 deg up to about 40, then a few packets at 60 and 61, then none to the south until 33,31,30 and 27. Then no more. Seems to match the expected gain pattern of a vertical 19" whip! Also path was 500 to 1000 miles or about 6 dB better between those angles. So so far, it looks like verticals are only good for the overhead passes (2 per day). So there still seems to be a good argument for going to a cross polarized antenna to pick up the other 4 passes. See the other message just posted about the 19" by 20" low profile PATCH antenna for your roof. Since this is my first reasonably documented successful pass, I cross posted this to the APRS SIG and AMSAT-BB also, incase anyone over there interested in mobile position reporting via AO-16 is not yet subscribed to the ao16aprs listserver... Sorry for the dual post... (send message to email@example.com and include "subscribe ao16aprs Your_Name") AO16 was not in use during this pass by any BBS users, although two stations did log on briefly (W4MO and W4FIN). ALso I checked IO-26 and it still has digipeat off.
