You'd probably have more success finding the external antenna and clipping the leads at the sharkfin.

- b112 3y agoJust make sure you do something, like use a resistor to ground the antenna lead, because I did that, and would still get connectivity at times. EG if the cell tower was very close. Was fine after I used a resistor to turn that power into mild heat.
- joezydeco 3y agoI wonder if one could build a metal cap, shape and color matched to the sharkfin, that goes over the antenna and couples to the roof of the car. Would that be enough to make a small Faraday cage over the antenna? Would leakage though the mounting hole still be enough to let a signal through?
- r0b1n 3y agoYou could maybe just stuff the inside of the sharkfin full of tinfoil.
- ragnese 3y agoI've tried stuff like that before on other things and haven't been very successful. Those damn EM waves really like to find their way through.
- brian-armstrong 3y agoI don't think you really need to get that sophisticated. If you unplug the antenna and send too much current down that antenna line, whatever's on the other side is not going to like it.
- TheLoafOfBread 3y agoIf it is similar to eCall in VAG ECUs, then there might be internal antenna inside the ECU itself.
