Hello I own a receiver as per the title. I need to connect an external 433MHz antenna to it. There is a SPIRALKA factory antenna fitted. . Please advise where I can connect the coaxial cable from the external antenna, as the manufacturer has not provided for this.

..is about 75ohm , as if anyone asked . Connect the screen to GND , and the centre to the antenna and don't bother with the transition

Solder one wire somewhere to the path as the antenna starts in the device, and the screen to ground. Ideally, this should lead to some sort of connector for the antenna on the outside of the chassis.

That's what I think. But please point out exactly where. Because I checked with a meter and there is a transition from antenna to ground. It's as if there is an antenna flush to ground.

Is no one able to tell me How to solder this antenna.
