Read moreHow far can X-band radar detect?
Microwave radars, also called X-band radars, which are limited by line-of-sight propagation to the horizon. Due to the large available bandwidth in the microwave frequency range, the spatial resolution can be as fine as 5 m at 5 km working range .
Read moreWhich are the frequency band used in satellite?
The major frequency bands used for satellite communication in India are S-band, C-band, Upper Extended C band, Ku band and Ka band . The INSAT/GSAT satellites carry transponders in these bands. 4.
Read moreWhat is the frequency of satellite signal?
Modern systems signals are relayed from a communications satellite on the X band (8–12 GHz) or K u band (12–18 GHz) frequencies requiring only a small dish less than a meter in diameter.
Read moreWhich frequency is high uplink or downlink?
In satellite communication, the uplink frequency is higher than the downlink frequency because the attenuation level increase with an increase in frequency. The power at the ground station (Base Station) is more than compared to the power available at the satellite.
Read moreWhat is the C-band frequency range?
Sometimes referred to as “mid-band,” you can think of C-band as the “Goldilocks” of frequency: not too low and not too high. It provides a solid mix of coverage and capacity. Operating in the 3.7 GHz to 4.2 GHz range, it sits between the 2.4 GHz and 5 GHz bands (the two Wi-Fi bands).

The amateur radio club at NASA Johnson Space Center in Houston retransmits audio on 146.640 MHz , and the club at NASA Goddard Space Flight Center in Greenbelt, Md., retransmits audio on frequency 147.450 MHz. The signals can be received for about 25 miles.
