Application: Receive-transmit system. Two units communicate with each other at 120 MHz and 10 W, in free space. Unit A uses a half-wavelength dipole antenna placed as shown in Figure. Unit B uses a 1/100 wavelength long dipole antenna and is 10 km from the transmitting antenna as shown.
(a) Find the current in antenna B when unit A transmits.
(b) Find the current in antenna A when unit B transmits.
