Hi Lew You could try a coax stub filter - see the one by G4SWX and described on the G(M)3SEK website http://www.ifwtech.co.uk/g3sek/in-prac/index.htm (Look for "Filters: Harmonic notch filters" under "The Best of In Practice").
I built one for 70MHz using RG58 and it works fine at 160W. The article recommends using RG213 for 500W. This looks a lot easier than messing about with metalwork and Ls and Cs. 73 Graham > There's a good design for a kilowatt-capable 6 meter low pass filter in the ARRL Handbook (2007), but I haven't found a design for a 2 meter LPF filter that I really like. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
