Amateur radio clubs often operate repeaters, usually in frequency bands near 144 and 430 MHz. They do not have the same power restrictions as CB radio. Calculate the minimum repeater height and transmitted EIRP for a repeater that must communicate with mobile stations over a 50 km radius, maintaining a minimum field strength of 50 mV/m at the mobile receiver, which has an antenna height of 1.5 m. Assume free space propagation conditions.
