I havea 1995 GS300.
the stock radio is out as well as the amp (out of car so it is bypassed).

I am using a aftermarket radio and using the built-in amp inside the radio.
I noticed that my antenna will extend fully upon turning on the radio, then it will drop about 6 inches. (the teeth are fine, the motor is fine). The relay for some reason will pulldown the antenna ( i watched the voltage flipflop to the motor).

Any suggestions on how to keep it fully extended?

Hmm I know that is how it works with the factory (goes up and down depending on the signal) maybe that feature is somehow still working with your aftermarket radio

yea, not sure why its picking up that signal, or maybe its just not picking up the correct signal which is causing it to retact immediatly.

I did however found that if I unplug one wire from the harness clip that goes into the antenna assembly it will go all the way up and stay up.
The issue then would be that I would have to get out of my car every time i wanted the antenna all the way up.

So, I drew up a schematic to make a circuit which will involve three wires (12+ constant, 12v+ switched, and a ground).
This circuit will switch on when the radio is turned on. it will count to 5 seconds, which will give the antenna time to go up and retract a bit. Then it will break the circuit for 2 seconds and reconnect it. That will allow the antenna to go all the way up. This should do it! Now I have to put the plans to actual PCB fabrication. This mod should only cost me about 3-10 dollars.

If anyone else has this problem and found a different solution, please post it. I will also psoot pics of the circuit that I build when its all finished.
