Save yourself a toll call, ICE has an 800 number: (800) 423-2666.
I think they charge less than $30 a piece for the bandpass filters.
I have a set of 6 ICE bandpass filters. They have worked pretty well,
though with only 15-25 dB of attenuation between some bands, I still
see some interstation interference. All antennas are mounted on a
single 14' mast, so I have what you might call a worst case scenario).
I have found insertion loss to be rather high on 20m and 10m, much
higher than the figures reported here earlier (100w in, <80 watts out).
Of course, this was measured with a wattmeter, not a spectrum analyzer.
But could there be 10-20 watts in harmonics? I'm using two TS-930Ss.
