AVAILABLE TRANSMISSION FACILTIES ON TELEVISION

Television stations transmit in one of two ways:

1. Very High Frequency or VHF

through signal – an electrical impulse – that is, broadcast to cover areas allocated to each television
station. All signals are transmitted by electromagnetic waves or frequency.

(MHz) MEGAHERTZ. It is a unit of frequency equal to one million hertz or megacycle.

ULTRA HIGH FREQUENCY (UHF): is a band of transmission frequencies between 300 and 3000
