Heano mhinduro dzenguva yakawanda dzeSB46 L. Matanho emutambo wepakati anowanikwa pasi -10 dB kuitira kuti uone zviri nani. Ndiyo girasi rakasara pa 0 ° on-axis (bluu trace) uye avhareji ye0 °, ± 15 ° uye ± 30 ° (ruvara rwekutsvaga). Pasi payo ndiyo inharaunda yepakati pa 0 ° on-axis (tsvuku yepepuru) uye inosvika 0 °, ± 15 ° uye ± 30 ° (machena machena). Iwe unogona kuona kuti mhinduro pamisara miviri iri pakati pe2 ne5 kHz inenge yakakwirira, iyo inogona kunge inokonzerwa nekupenya kuduku kwandakanzwa.
Izvi chaizvoizvo zvisingatauri zvakaperera kugadzirisa bharani, kunyanya mumugwagwa wepakati, iyo inonyanya kuvhara kusvika 6 kHz. Chati inotevera inonyanya kuzarura, zvakadaro.
