Lectrosonics 21793 Female BNC to Female BNC RF Adapter

The Lectrosonics 21793 is a female BNC to female BNC RF adapter designed for wireless audio system integrators, touring engineers, and installed sound technicians who need a reliable, low-loss interconnect at 50 ohms. It serves as a straightforward solution when interfacing cables directly to whip antennas or joining two coaxial cable runs in a distributed antenna system.

In live production and installed environments, adapter quality directly affects RF signal integrity. Generic adapters introduce insertion loss and impedance mismatches that degrade receiver sensitivity. The 21793 is built to Lectrosonics specifications, ensuring the 50-ohm characteristic impedance is maintained across the connection and that signal loss is kept to a minimum. This makes it a dependable choice for rack-mounted receiver setups, antenna splitter configurations, and remote antenna placements where maintaining clean RF paths is critical.
