i have designed yagi uda antenna considering a channel works on frequcey 199.25 mhz chanel 11 in north cyprus... using 4nec2x and get these results number of elements 5 and the gain is 9.7 and input impedance was 44.5-j32.03 and effecency was 96.88% so according to theoritical part i think i got good results coz gain is high resistance is good to match 50 ohm and effecncy have high percentage so what do u think dear friends of my results and how does this negative value effects on my design
