We have a 2006 Bounder & there is no booster button switch, what you call a "traditional booster". The booster is built into the distribution box - the black box that has all the buttons on it that read:
DVD SAT ANT VCR CABLE. There will be a set of buttons for each TV in your coach (probably 2) a set labelled for VCR RECORDING (for way back in the ancient times when coaches came with VCR's

)
I'm going to assume you still have the RCA CRT TV's in your coach that came with the 2006 models. If so, & you are using a DTV converter box, you need to have the ANT button pushed in that corresponds to the TV you want to receive stations on. That should be all you need to do.
Now for some really simple questions (please don't be offended, I've done one or more of these before myself. We've since replaced the CRT TV's with LED HDTV's):
#1 Is the power on to the DTV converter box?
#2 Is the antenna up?
#3 Have you tried rotating the antenna & re-scanning?
#4 The TV in the bedroom is powered by the 12v inverter (ours is). Is the inverter switch turned on?
