If you want a one dish solution....
A nice eliptical dish would work. If you can find a old Primestar dish or maybe a starchoice dish.
I have a Channelmaster 76cm elip that I've set up in the past with 82, 91, 101, 110, and 119. They were all circular sats, which are much easier to pull. I only used the 101 slot for aiming. Since I don't have either provider anymore, I just use it to play around with now.
I was using it recently for the 97 sat. Granted it was a very ghetto setup (dish pointed out a open window in the guest bed rm; leaning against the bed). Max signal i got with my Classic NA was around 58-62. That was with the lnb in dead center.
In your setup, you will need to point to the 91 so you may need a bigger dish than what I used to get the 97. (hence the starchoice/primestar suggestion). If you go this route, I'd get a invacom QPH-301 so you can get channels off G11) A standard KU Lnb for 97 and a reg Circular lnb for 82
HOA can't limit # of dishes. They can only limit dish size (1m max in 48 states; AK is different)
