Hello,
I need to transmit 10 Mhz to 100 Mhz Frequency Sweep equal in all directions so the antenna gain is about 0 db, but the thing is really matter is the antenna size.
for 10 Mhz---- λ=30 M ---- (λ/4) = 7.5 M
for 100 Mhz---- λ=3 M ----- (λ/4)= 75 cm
Because the frequency varies from 10 Mhz to 100 Mhz , the antenna lenght varies from 7.5 m to 75 cm.
What kind of Antenna Should I USE???
