If everything else failed.
If you cannot get anyone else to install it for you, call this guy back.
Ask him to install 1000.2 in place of Superdish.
Even if for some unknown reason he cannot get good signal on 129 from 1000.2 ask him (or do it yourself after he leaves) to cover 129 feed on 1000.2 LNBF with half of an empty soda can or folded few times kitchen aluminum foil
Make sure to secure this cover (zip-tie or ductape)
.
Then feed 129 signal from small 500 to 1000.2 LNB IN slot and you're golden.
Good luck.
