Re: [A/S] Installing Batwing antenna

Sarge,

The Winegard can be mounted in the same hole the Braund is in and will 
lay down in the same space.
One basic difference between the two is that the Winegard has an 
amplifier in the head and the Braund's amplifier is in the wall unit. 
Changing antenna's requires changing the wall unit as well. The Winegard 
puts 12V on the coax cable to the antenna and picks the TV signal off 
the same coax. The Braund can be used with the wall amplifier on or off 
depending on signal strength. The Winegard must be turned on to get much 
of anything. Good but different.
The installation challenge is the Airstream installed 300 ohm flat lead 
antenna wire. It was good stuff in it's day but 75 ohm coax is better. 
They just don't work together.
You have two choices. As mentioned you can run wire along the roof and 
down through the refer vent or you can convert using a little in line 
transformer often called a balun, from Radio Shack or the like.
The roof connection can be done so that it is inside the roof. The 
inside connection would be in the wall behind the wall unit.
The roof penetration for the antenna lead is a small plate anchored and 
vulkemed in place. By opening it up you can pull a small amount of 
slack, make the connection using the small transformer and stuffing it 
back in the roof and closing up the penetration so only the coax is 
exposed. Be sure to leave enough slack to allow the antenna to rotate fully.
When you pull out the old amplifier to replace it you can make the new 
connection and stuff the pieces in the wall. The new power supply fits 
in the same hole.
