We get a lot of calls from customers who want to keep unity gain between their remote antenna and receiver or distribution rack. This often requires a Rube Goldberg contraption of in-line amps and attenuation pads to ensure the same amount of energy coming in to each stage is the same as it goes out.
While keeping unity gain in super duper high stakes environments like national broadcast events might be a good idea, to eliminate every possible variable that could go wrong, it simply isn't necessary for the vast majority of wireless audio applications - that means you and yours.
