I guess I feel bad for the few hams here and on the air who seem to find it difficult to get on these amazing birds.  

Below is a link to an ultra-portable ultra light weight setup for working these birds with a HT (4 watts). The Duplexer is zip tied on the short center boom and the coax is just some RG-8X.  A set of short (24 inch) home-brew Yagis are set at fixed elevation of about 30 degrees, and don't need any phase angle rotation.  

The camera mount center rod was replaced with a 1/2 inch PVC pipe, which can be raised to catch very low angle passes, and lowered in windy situations.  The HT, a headset, an old android smartphone and a small writing pad completes the setup.  

AO-91 and AO-92 can be worked down to 3 degrees full quieting, beyond the hills, from my city lot house back yard.

Actually, it would take a bit of work to NOT work these sats, happened once when the coax cables to the duplexer were reversed ! 
Good luck to the folks trying hard work them, wish I could help...
