Ok my learned friends, I have a question.
On my latest project I am using these 433MHz Learning Code Receivers, and on final assembly of the project I was only getting about 12" of usable range. Not good, I hear you say.
Thinking that there was a problem with the antenna mounting, I put my meter on buzzer and discovered that the ANT connection was connected to the GND terminal of the receiver, ohms reading later, less than 1 ohm.
This has surprised me, and need to know if this is normal ?
I'm using a short stubby aerial, M6F mounting onto a length of M6 stud which screws through a nylon carrier onto an exposed land on the PCB, this connects to the ANT terminal on the RX480-E. Obviously the outer casing of the project is also GNDed, so how does thsi work ?
