Antenna reception affected by person.

  1. Aug 7, 2010 #1
    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.

    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
