Amplify forward protocol for multiple parallel relay. here I have used 14 group of parallel relays starting 1 relay , 2 relay group to till 14 no of parallel relays to form 14 different number of relay. This mainly used to find the difference between band gain for addition each relay.-Amplify forward protocol for multiple parallel relay. here I have used 14 group of parallel relays starting　1 relay , 2 relay group to till 14 no of parallel relays to form 14 different number of relay.
