I think my PB said it can do 100ft easy but from inside the house it can get dodgy if you have walls with lots of pipes and wiring.
I don't think we'll need the booster. The wireless controller will only be used when we're outside using the spa, and we'll be well within 100ft. But, good to know the antenna exists. It's not even listed on their brochure.
