RF (50 ohm)

Antenna cabling for radio microphone and in-ear monitoring racks: Sennheiser GZL coaxial cable in standard RG58 and low-damping RG8X grades, Shure UA-series 50 ohm assemblies from 1.8m to 15.2m, front-mount antenna cable kits for receiver racks, and an empty cable reel for managing longer runs.

Everything here is 50 ohm, which is the point: RF antenna paths need 50 ohm cable end to end, and substituting 75 ohm video coax introduces mismatch and loss exactly where wireless systems can least afford them. Cable loss rises with both length and frequency, so short jumpers are fine on standard RG58 while longer paddle and antenna-distribution runs justify the low-damping RG8X grades. Keep runs as short as the rig allows, and get antennas out from behind the metalwork with clear line of sight to the stage, which is what the front-mount kits are for, bringing receiver antennas to the rack face properly cabled.

Matching BNC connectors live in the connectors section for anyone terminating their own runs.

RF Cable FAQs

Why 50 ohm specifically? Antenna runs are 50 ohm systems, video coax at 75 ohm half-works and quietly costs you range. Everything here is 50 ohm for exactly that reason.

RG58 or RG8X grade? Loss per metre decides: standard RG58 for short racks, low-damping RG8X for longer runs to paddles. Cable loss is the silent killer of wireless range, the maths lives in antennas and RF distribution.
