Hello everyone.
So, I have a problem that's leaving me scratching my head. My boss bought me a brand new RF Venue diversity fin antenna to help with the numerous dropouts that occur with our old Shure ULX P4 and ULX S4 systems. (eight receivers each) These receivers are rolled onstage in a travel rack whenever we need more than eighteen lav mics in a show, and are snaked into the booth. (the first 18 mics are Sennheisers, no problems with those)
Most of the time, the Shure's have awful range, less than 30 feet with complete line of sight. The new antenna gives fantastic range, 4-5 bars over 100-150 feet behind two feet of brick wall, but it only seems to work if you hook it up to a single receiver at a time, using a distributor (Shure) kills the effect and reduces the range to 20-30 feet or so.
Is my distro bad? I'm using 75-ohm BNC cable to connect the antenna to the distro, should I be using 50-ohm? Am I missing something important?
Thanks in advance for any help you can give.
