A home-built low-pass filter for 4m
To suppress unwanted harmonics, it is recommended to use an extra low-pass filter LPF with a 4-meter transmitter
A diode-switched band-pass filter
expensive than working with mechanical switch
A low pass filter circuit
these two filter circuits is a circuit that will only allow passage of those frequencies that are neither too high nor too low
