Hey John and :welcome:
I didn't install mine but Jayco did it and it is the new style. I have a 16.49-3OB and it is installed above my table if that helps?
Cheers
Ants
Noticed a few new Expandas at Prestige with the antennas laying back on an angle onto the front of, and sticking up higher than the air conditioner. Could be something to watch In tight spots.
I did the retro fit from the old style to the new because my old Winegard antenna had ceased to function. Can't help with location other then to suggest, like Jayco, close to the van entry point and the power supply.
I reckon Jayco put them wherever convenient at the time. I've seen them in a few spots. Mine is directly above as you walk in the door. Not a great spot because you bump your head on it when you have the poptop down. Would have been better above the dinette.
