Replacing center roof vent in a '79

[blickcd]

My trailer originally had three of the old light/vent combos. Over the last few years I replaced the living room one with a Fantastic Vent, and in the bedroom I installed a modern roof vent with a metal lid and covered it with a MaxxAir Turbo Maxx fan.

For both applications I installed a light fixture next to the fans. Reason I didn't go with a Fantastic Vent in the bedroom is that I wanted something that would run rain or shine and when closed would not be a skylight over my bed.

Now I'm looking at the center vent, which is in the galley area. I'd like to put a modern vent with a transluscent or clear skylight lid there and my usual light fixture, no need for another fan, but the TV antenna when lowered, has a loop that almost rests on the lid and I don't want it damaging the lid.

I've attached a photo taken when I was replacing my air conditioner and you can sort of see the vent and TV antenna situation in the background.

Maybe that loop can be inverted for a few more inches of clearance, or perhaps it is nothing to worry about.

I'd like to hear from those who have replaced their center vents and have the same TV antenna situation as mine and how it has worked out. Regardless, I know the antenna would have to be raised at least a little in order to open the vent.

Thanks,
Christopher

I replaced my center vent with a power FanTastic fan, but I removed the television antenna and it's currently in cold storage and will not be re-installed.
