Indeed, in a camper, look for the satellite after each start.
The buzzer has a significant delay that's why you have to be very slow in handling the dish.
To tune the dish with the beeper, whenever it is necessary to return to the menu while many demo possible to wedge staying on the last viewed channel.
For an RV, always feeding 12 volts cigar lighter, you have a reference for the remote control, you need a precision beeper. This is not the case.

This is not Amazon that is concerned but BFSAT professional should offer the product best suited to the camper.
