Did your year of Disco have the antenna outside for the stock radio? Interesting. Mine is in the rear windows I believe, and Ill be honest it kinda sucks.
My '98 is the same (in the windows) but it has an amplifier, which is typical of cars that have an antenna in glass. If yours isn't working well it might be worth your time to see if you are getting power to the amplifier (yeah, you have to drop the headliner) and also verify that the amp is actually working (I've got no idea how to do that) or get a salvage unit to swap in.
Actually, I'm ASSUMING my '98 is the same based on a glimpse of what's up there. My '02 has had the headliner out more than I care to recall and it definitely has what I'm describing. The '98 looks to be the same from what I've been able to see.
Was was wondering if I could extend the range of the radio, that's all.
Thanks Jim! I am trying to find one online.I love the factory radio and the weather band! You can use any universal antenna, I've been running one for years, just make sure it's flexible.
