Yes 64 channels without any booster, but I'm really not sure my 1999 trailer had a working booster ever, or at least as long as I've owned it (5 years).
It doses have a sliding switch on the combo 12 volt/coax plate, and there is a tiny circuit board on the back of it, but the tiny red LED doesn't light up in either switch position.
I should ad that I live 10 miles from New York City where a lot of broadcasting comes from.
