Hello Martin,
I use 2 x 5 elements yagis, for UHF & VHF horizontaly polarized on the
same boom inclined 25 degrees up, using FT-897 or FT-736, handled by
only azimuth rotator.
Decent results for FM and SSB Sats throughout all the pass.

Hi Martin,
I think you've analyzed your situation pretty well when it comes to numbers
of elements, beamwidths, etc. A few thoughts:
- if you can try a few satellite passes from around your property with a
handheld yagi, like an Arrow just gain a little first hand experience to
see what your minimum elevations are going to look like.
- you might be surprised to find that some houses are more "transparent"
to VHF/UHF signals than others. There are several ops here who regularly
work satellites with portable antennas from inside their houses. Don't
consider every obstacle to be impenetrable.
With all that said, if I was in your position I'd go for a 3 or 4-element
2m yagi and I'd go to the extra trouble of getting crossed yagis so you can
use circular polarization to reduce signal fading. For 70 cm the
7-elements on my Arrow handheld antenna has always been sufficient, and go
for crossed yagis again. If you think the trees will really be a problem
then go with 4 elements on 2m and a few extra on 70 cm, but realize that if
you're buying commercial antennas you're stuck with what the sellers
offer. This is about as much as I'd want to swing around with an
inexpensive azimuth rotator (You didn't say what kind of rotator it was)
Finally, my antenna situation at home was even more awful than yours. My
back yard was smaller than my living room and it was surrounded by 3-storey
townhouses on all sides. I decided to become a rover and it was the most
adventure-packed 2 years of my life! I travelled all over eastern VE3 and
western VE2 and activated just over 70 grids, many of which had never been
activated before. Amsat ops are always looking for new activations and are
very grateful to thos who have the chance to get out there and activate
them.
I hope this helps a little. You'll get plenty more replies and have lots
to sort through soon!
