Web25 de mai. de 2024 · 111. SLK001 said: Putting a reflector behind your antenna will only work if the frequencies are interger multiples of each other. If so, then use the half-wavelength of the lowest frequency. Other than that, you might need to simulate your design to see the effect of the reflector position on each frequency. thnak u for ur reply.
