I am constructing a device that has 3 PIC:s on the PCB and a lot of other components. I also have a 433 MHz AM radiotransmitter at 10mW onboard. I am thinking about the antenna for the transmitter. Should i connect a piece of wire in the box, or should i make leads on the board and use as an antenna(would that work)?
How long should the antenna be?
