Any experience with active multicouplers that support up to 1500 MHz. I am using Stridsberg active multicouplers up to 1 Ghz successfully now. Applications would be ADS-B, GPS, Inmarsat.
I haven't actually bench tested the MCA216M, MCA208M, and MCA204M's that I have because spec'd upper limit is 1GHZ and assumed attenuation at 1.5GHz would be unnaceptable.
