Answer / m

frequencies in Ku band are subject to obsorption by rain
water..

Answer / talha arshad

High frequency means High data rate (Advantage)
small wave length mean Small Antenna (advantage)
small antenna mean low cost (advantage)
small antenna means easy to install (advantage)


High frequency means maximum chances of attenuation
(disadvantage)
low coverage area as compare to C band (Disadvantage)

Answer / gerald francis suresh

in the frequency spectrum C-band starting from 5,925
MHz to 6,725 MHz and 3,400 MHz to 4,200 MHz and the Ku-band
starting 13,750 MHz to 14,450 MHz, 12,200 MHz to 12,750
MHz,11,450 MHz to 11,700 MHz and 10,950 MHz to 11,200 MHz;
the advantages between ku band and C band is, low
frequency (C band) means speed is low, so need high power to
transmit long distance and need big size dish for reception
and noise level is high and band width is high so no of
channels very few.
so the opposite is KU band, so KU band is efficiant
and more reliable for communication.

Please, give me the simple circuit dig. for "oscillator with variable frequency & upto 6W". I will be very thankful to you.
