I knew we had one on our 183 and also have one on the 19 now also. I had seen the older one in the upright postion but have not seen the new one in the upright position no matter what is turned on. Think it is the radio antennae.
On this trailer I know the TV antenna is the only thing that rises when you turn the crank. Not sure if it is supposed to rise simultaneously with that or not. I could not see the antenna on my old model when we were camping with it.
It is the radio antenna for the Concertone and has nothing to do with the TV. I keep mine folded down too since it adds about a foot to my height. Driving through a 12 foot high gas station canopy with it up will break every fluorescent tube in the lane.
