A satellite transmitter operates at 4 GHz with an antenna gain of 40 dBi.  The receiver 40,000 km away has an antenna gain of 50 dBi.  If the transmitter has power of 8W find power delivered to the receiver?

What would be the effect on the receiver signal level of making the transmitter power 5 times stronger, express your answer in dB.

A cellular radio transmitter has a power output of 5W at 600MHz. It uses an antenna with a gain of 3dBi. The receiver is 5km away, with an antenna gain of 12 dBi. Calculate the received signal strength in dBm, ignoring any losses in transmission lines.

An isotropic radiates 200W of power in free space calculate the electric field intensity at a distance of 10km from the source.

A satellite transmitter operates at 16 GHz with an antenna gain of 45 dBi.  The receiver 45,000 km away has an antenna gain of 40 dBi.  If the transmitter has power of 100W find EIRP in dBW

A certain antenna has a gain of 8.7 dB with respect to an isotropic radiator operates at 350MHz. How much power would it absorb from a signal with a field strength of 100uV/m

Consider the impact on the signal level at the receiver if the power of the transmitter were to be increased by a factor of 20. How would this change be quantified in terms of decibels (dB) without actually calculating the value?

A transmitter has an output power of 150W. It is connected to its antenna by a feedline that is 15m long and properly matched.  The loss in the feedline is 1.5 dB / 100m. The antenna has a gain of 6.5 dBi

A certain antenna has a gain of 6.2 dB with respect to an isotropic radiator operates at 200MHz. How much power would it absorb from a signal with a field strength of 30uV/m

Describe how the signal level at the receiver would be altered if the distance from the transmitter were to be increased by 20%. Express this theoretical change in terms of decibels (dB)
