The bandwidth is 20MHz for our common yagi antenna of 400MHz.
But why do some customers need the 40MHz or above.
And when the engineer tunes the frequency, it really can make it.
Why, I do not understand?
I am not an engineer for the antennas, for an antennas sales, should the sales be an engineer also?
