27dB Directional Coupler（UBDC-1127L）
27dB Directional Coupler F-port center conductor seizure mechanism is a 4-sided coaxial structure that provides 8-coaxial contact areas precisely formed in a progressive die.
Impedance: 75 Ohm
The tooling is highly polished to render a smooth finish. It is also designed to eliminate parting lines along the ports for an optimum weather seal. Sand blasting of the casting is not allowed since it increases the surface area substantially.
