The stuff you can bury is called "flooded" cable. The regular stuff will last about 10 years in the ground, do any of us think Dish will be around in 2035?
I hated installing this monstrosity, that LNB setup was a joke and the thing was so big it needed support struts. Then there was all the wiring to the switch...
Luckily I haven't had any Wi-Fi issues with mine or the ones I've installed for others. If it doesn't work out you can always return it.

iirc you can't have a switch down line from any twin. It's been a while, I installed thousands of these back in the day but that was over 20 years ago! Took the first 501 that came in home with me, think it as April 2001. Loved that receiver.
