Re: BPF 80m

Alan G4ZFQ

I have built a number of these bandpass filters, and, with the exception of the 80 meter filters, the insertion losses have all been below 2dB. I have been unable to achieve a loss of less than 5dB on either of the two 80 meter filters I have built.
I cannot answer your question but why worry?
On 80m it will not matter, antenna noise is high, an attenuator is probably more useful rather than lower loss.
