Perhaps I am simplifying this, but I see significant improvement in my systems by 1) testing the cable in advance of shows on an IFR to insure the connectors and cable are good, 2) stretching out the cable when in use, and 3) testing the best paddle positions for ideal coverage on each set-up . When I've used 50' or 100' loops or bundles, I have seen a loss of 6-9dB on the receiver itself- so it was easy to see the light! |
I will try this tomorrow on an IEM system I am using that could use a little extra range.
I'd like to know about the IFR, and which tests you perform. Futhermore, for cable that is either part of rental stock or sees alot or touring how often would you recommend the cable be tested?
I tour with a small theatre show that tours our own RF cable - precisely because too many places provide us with 3532s coupled with nothing but 60' RG58 cables - makes it very hard to get clean reception at 300' and beyond. I wonder if we should find a local audio house (System Sound maybe) or RF specialist that can test the cables between tours.
