The relay coil energizes and remains in that state as the antenna fully
extends. The hot power feed passes through the relay contacts, motor, SPDT
limit switch to ground. A timed rotating cam then engages the limit
switch to off, which removes the power feed to the antenna motor after
full extension. When the radio or ignition is turned off, the relay coil
is de-energized and the re-directed hot power feed passes through the
relay contacts, limit switch, motor and ground in a reverse polarity path,
allowing the antenna mast to retract. Once again, the cam engages the
limit switch to off, removing the power feed to the antenna motor after
full retraction. That's my best diagram interpretation...

BTW, in regard to your other post, I was able to purchase the original
antenna wrench from the dealer when I replaced the mast in our 92 Accord.
As for grease, mine had plenty of residual on the drive gears inside the
antenna housing to self lube the new drive cable. Be sure to remove any
broken cable inside the housing. After installation, torque antenna nut to
20lbs-in...HTH
