I am planning to buy one of the antennas(SR04C33-R) that you produce. The thing is I would like to know it's impendence at the working bandwidth. It is saying that the impedence of the antenna is 50ohms when matched but I am wondering what is the input impedence of the antenna at 800MHz (let say 50+j20, 50-j20, etc.). Besides, in the datasheet there is a circuit that 2 components' values are given. Does this mean that at 800MHz it is matched to 50 ohm real impedence and according to the stubs that we will add we need to add the rest of the values in the circuit.
