>ICE filter for 40m with generous Q=200 will attenute >30dB on 80m, > >20dB on 20m, >30dB on 15m ultimately approaching -50dB on VHF giving >a GOOD TVI protection. Modelling won't accurately predict VHF attenuation of this kind of filter unless you have included the correct values for parasitic inductances. The most significant ones are the inductances of the capacitor leads. -- 73, Scott K9MA sdelling@facstaff.wisc.edu |
