Why does television signal improve when you hold the aerial?

Essentially when you grab the aerial, you’re typically increasing the size of the aerial and then to take your body sort of conducting electrolytes. And a good example of this would be in a laboratory if you have an oscilloscope and you look at the pick up from the main frequency, you can see a 50-Hertz signal which is to pick up from the resonance (circus) in the room. And if you hold the probe in your hand, the amplitude of the pickup increases dramatically and the same thing happens when you grab the TV aerial, you’re improving the pickup and it’s then using you to resonate within the circuit to produce the signal within the televisions. And the TV has to tune quite closely to the right frequency but when you touch the aerial it will improve the signal dramatically. The other thing is when you grab on to the aerial the connectivity between your fingers and aerial and tightly squeeze on the aerial or if your fingers are wet and the conductivity between you and the aerial will be improved. So it often depends on how hard you squeeze the aerial.
