****Warning****
***N00b alert***
Hahaha, so we got that out of the way. This thread may make you pros facepalm, but please bear with me.
I've sneakily built an antenna in my back garden, and as I don't have any radio licence (yet), all I can do is listen to or for signals.
It's a simple 9m long antenna, however I haven't got any components to create a specific reciever quite yet. I thought that if I hooked up a sine wave to it at a resonant frequency, I might be able to detect any changes in voltage along the wave on oscilloscope - to see my basic setup, please look at the attachment.
Now if I'm feeding this resonant signal into the antenna, (graph 1) shouldn't I be able to see where any radio waves picked up by the antenna have either added or subtracted from the original wave? (graph 2)
I'm sorry if this makes you guys cringe, but I'd really like to get a grasp of radio, and I reckon the best way is to experiment.
