Hello you guys,
I've got this wireless doorchime with a promised range of 100 meters. But because of my needs, the transmitter will be placed close to the ground (a few cm) and the reciever about 140cm from ground. This give me a range of 26 meters on an open parking lot, and only 16 meters on the lawn.
So, what can I do to increase the range? I think the obvious thing to do is to modify the PCB antenna - am I right?
The transmitter antenna should be as small as possible (10-15cm in size), and the reciever antenna can be a bit larger (30-40cm in size).
Here are 2 high res pictures to study - it shows the PCB antenna and most of the circuits.
I would rather change the reciever antenna, since there are many rules and regulations in my country regarding radio transmissions. I presume this door chime respects those rules since it's a common supermarket product.
Regards,
Futterama
