Off hand I can but guess 'addition' of your body to the antenna structure enhances gain and, hence, improves the S/N ratio...when I grab my am antenna all the static disappears. What is going on.
Is there some way to make this happen without me having to hold the antenna --something else to attach to the antenna?In many receivers, when a signal is weak, the electronics tries to make up for it by increasing gain of the RF amplifier. By increasing the signal strength with your body as an antenna tuner, receiver gain is decreased, thus decreasing the noise and static being amplified.
As previous posts have advised you -- It's about increased signal strength, AGC response and improved S/N ratio attendant thereto - your next move would seem obvious!? (IOW have a gander at post #6)Is there some way to make this happen without me having to hold the antenna --something else to attach to the antenna?
