Re: Power Antenna

Here are a few photos of an antenna disassembled. Note that I have no idea what the proper name for each piece might be so I made up my own.
I believe the part you are asking about is removing the drive cable from the reel assy.
First photo shows the assy with protective cover off, reel cover exposed and then second is the reel cover removed. You can see a nylon cable retainer with multiple springs pressing the cable tightly into the slots of reel drive.
Third and fourth photos are showing the retainer partially removed and the use of a small screwdriver to GENTLY pry the retainer up and away from reel drive. Note that the retainer can be brittle and springs are not attached and will go flying when tension is released. Work slowly not to force the nylon and corral the springs. Fifth photo shows the retainer and springs removed and set aside.
Sixth photo show the cable being fed up and mast and housing being separated from motor assy. Note that there is a small O ring or grommet which fits between the lower insulator and a recess in the housing. Not exactly sure what the function is but it is there. Maybe a water or dust seal.
Seventh and eighth photos show cable reinserted in drive reel teeth, wrapped around and taped in place to keep it out of the way while the spring retainer is being reinstalled. Reinstall the spring retainer just as it was removed. GENTLY. I installed a few springs, slid it down a bit to hold those springs at one end, inserted a couple of more and slid that section down etc until it was back in position.
The last photos just show various parts. Top insulator slides out of tube housing as does the bottom insulator. The antenna connection insulator is in the tube and is pushed out from top and comes out the bottom once the terminal is removed. That connection should not have to be disturbed to change the mast. The actual connection is a terminal with a flattened tab which fits into a hole in the insulator. Once in the insulator, the flat tab is bent over and when mast slides into position it is forced against the bent over tab for the connection.
