Hi all, Does anyone know of a decent 2m bandpass filter that can be left inline on transmit with 100W? I see them for 6m and below, but not 2m. I've found this: http://www.antennas-amplifiers.com/2m-

My problem is that I am going back to only doing 2m during contests and I "need" two filters (144 - 146 and 146 - 148) to separate the FM side which is planned for 350 watts and the fun side which is
