Trying to connect an antenna (a wire>10m) to a bandpass filter (BPF)
It's important for me to know the impedance of the antenna
Thinking of using a 51 ohm resistor - using this resistor across the end of the wire to ground and then coupling to the BPF (this way the BPF sees 51 ohms- assuming the impedance of the wire is much larger)
But think not a good idea to add a resistor there.
Use an emitter follower?
Please what am I missing/ what can I do?
Thanks
