Wilson Electronics 859926 10 dB Inline Attenuator, 50 Ohm, N-Female

The Wilson Electronics 859926 is a passive, fixed-value RF attenuator that adds -10 dB of loss to a 50 Ohm cable run. It installs inline between two lengths of coax and has N-Female connectors on both ends. That makes it a direct fit for the N-connector cabling used in Wilson and WilsonPro commercial signal booster installations.

Integrators and installers use a fixed attenuator when a signal path carries more level than the connected equipment needs. A common example is a donor antenna that sits close to a strong tower. Inserting a known, repeatable 10 dB of loss lets the installer tune the system without swapping antennas or changing cable lengths. The 50 Ohm impedance keeps the attenuator matched to 50 Ohm coax and components, so it does not create a mismatch of its own.

The unit is compact at 4 x 1.5 x 1.5 in. and weighs 0.25 lbs. It can sit in a cable tray, equipment closet or behind an amplifier without separate mounting. Because the value is fixed, the result is predictable, and the attenuator can be documented in a system design like any other component. Keep a few on hand for commissioning visits where on-site conditions call for less gain than planned.
