Answer:
An antenna coverts electrical energy into electromagnetic waves at transmitting end and it will receive the transmitted
signals by receiver end and again converts into electromagnetic waves into electrical signal.
Very High Frequency VHF of frequency range 30MHz to 300MHZ with wavelength 1m to 10m is uesd.
This type of propagation is called as line of sight communication.
If H is height of transmitting antenna, then signal can be received
up to a maximum distance of
d= √2RH
if heights of transmitting and receiving antennas be hT and hR.
