DC Block Inner/Outer 380-2700MHz 250W/3kV 7-16(m-f)
HR-28D
Please Register or call for more information
Microlab HR-28D is used to prevent the flow of direct current and low-frequency current surges along the inner and outer conductors of a transmission line while permitting the unimpeded flow of RF signals. Applications include the blocking of current surges in subway tunnels and at antenna sites during lightning storms. The unit consists of a coaxial line with a series capacitor in both the center conductor and outer conductor to block the flow of low frequencies while passing RF with negligible loss or reflections.
