8. (a) A parabolic antenna with a diameter of 0.75 meter is used to receive a 6GHz satellite signal. Calculate the gain in decibels of this antenna. Assume that the antenna efficiency is 75%. (b) If the system noise of a satellite is 300⁰ K, what is the required received signal strength to produce a C/No of 75dB? (c) If a satellite is 36,000 km from the antenna of (a), what satellite EIRP will produce a signal strength of -105dBm at the receive antenna? Assume that the transmission frequency is 6 GHz.

(a) A parabolic antenna with a diameter of 0.75 meter is used to receive a
6GHz satellite signal. Calculate the gain in decibels of this antenna. Assume that
the antenna efficiency is 75%.
(b) If the system noise of a satellite is 300° K, what is the required
received signal strength to produce a C/No of 75dB?
(c) If a satellite is 36,000 km from the antenna of (a), what satellite
EIRP will produce a signal strength of -105dBm at the receive antenna?
Assume that the transmission frequency is 6 GHz.
