I have a antenna in my room & it runs to my tv tuner.

Just curious why the reception of the signal is affected by a person moving around the room? Even swaying your arm slightly affects it.

thanks.

because the wavelength of tv antenna is in the same order of magnitude with your hand.
A UHF frequency have wavelength between 10 cm to 1m while VHF frequency have wavelength between 1 to 10 m. [data taken from Wikipedia]

Hope it explains
