Airfoil antenna??? and Automatic Radio repair..

[pwillis44]

Hello All,

I have my truck running. Took it to the Cumberland Run in Tenn. and Beatersville car show in Louisville KY this weekend. Good Stuff.

I am in the works of repairing the aftermarket radio. It is a Automatic Radio model # DUP-4151. AM only ... Does anyone here know where to get these repaired?

AND

To get better reception do I need to fool with the screw knob on the side where the antenna is? I am really trying ot get this radio working since I decided NOT to cut my dashboard and found a new speaker.

ALSO What is an AIRFOIL Antenna. I have found a couple of antennas on ebay but do not know where to start. MOST say fits a mustang or galaxie. And they have two set screws on the side. And I can't figure out what part to buy from carpenter or LMC. Did these antennas use the same mount? I have a rounded end with grooves for my post. Will one of these mustang antennas work?

Please advise on all. This is the best site for vintage trucks. You all have helped me get my truck on the road. 2 shows in one weekend three days after I got the truck running. I only had to change the themostat on the side of the road. Not bad for mayden voyages... Thanks look forward to more help...
