A VHF transceiver is connected to a VSWR meter and 50 2 dummy load as shown in Figure 1. The output power from the transceiver is measured to be 25 watts. The reflected power is 100 mW. The dummy load is then replaced with the dipole antenna that has physical length of 40 cm and gain of 2 dBd. The reflected power is again measured to be 500 mW. Calculate the following: Figure 1: Practical setup of output power measuring instrument 2.2.1 VSWR. (2) (1) (3) (2) 2.2.2 Frequency of operation. 2.2.3 The effective isotropic radiated power in dBm. 2.2.4 Power received at 30 km with receiving antenna gain of 10 dBi. 2.2.5 The electric field strength at a distance of 40 000 m from transmitting antenna.
