Thread: Bandpass filter 1 kW level

    Default Bandpass filter 1 kW level

    Hi Contesters, multi radio users,

    Here at PI4CC we have 6 towers in a 60 meter by 60 meter lot. With power at 1 kW level we got a lot of RF in this small space
    To prevent overloading we used W3NQN and coax notch filters. Lately we developed bandpass filters for the 1 kW level and tested them with good results.
    Have a look at to see the project. And perhaps is a solution for you.
