please solve all options a,b,c and d step by step... thank you

I need a full and clear expert solution for handwriting.

1. What are Radio Frequency bands and its uses? (Give its definition and Give at least 5 examples of each Frequency band/range)   2. What is LORAN? Explain its function.

(B) A commercial 50 92 Radio Shake coaxial cable is used to carry RF signal power from a transmitter to an antenna of 300 2 as a load through flat antenna transmission line with 300 2 characterstic impedance as shown in Figure 3. The above situation would happen if we connect the coaxial cable to the antenna without a matching techinque. Determine: 1- The reflection coefficient at junction B. 2- The input impedance at point A. 3- The reflection coefficient at junction A. 4- The fraction of the reflected power. 5- The fraction of the transmitted power to the antenna. 1²=0 5052 30052 (B) Z₁ = 30052 Figure 3
