It’s not only how they tested mobile networks.
The old Nokia and Ericsson phones as well I think as some Motorola’s had a rubber plug in the back just below the external antenna with a coax port that you had to remove when you plugged the phone into the a car speaker phone system the phone would then hook to an external or a larger antenna glued to the windshield.

- dogma1138 7y agoThe external port was a requirement for kits like this https://images-na.ssl-images-amazon.com/images/I/411PQXERG6L._AC_.jpg https://images-na.ssl-images-amazon.com/images/I/411PQXERG6L... But signal testing kits also used it. This survived until 2G the 5110 still had it. When 3G came out the coverage was good enough and I’m guessing that issues with signal strength in cars was more or less solved.
- ThePowerOfFuet 7y agoWhat a blast from the past... I remember installing that exact kit (plus antenna) in my own car some twenty years ago. It worked great.
- perl4ever 7y agoYou know I remember a Motorola v120 having that. It appears that's what it was.
