1251000 MHz Lightning DC Blocked Filter Protectors N Female Connectors
The PolyPhaser IS-50NX-C2 is a DC-blocked coaxial RF lightning surge protector with N female connectors on both the antenna and equipment ports, covering 125 MHz to 1 GHz. It combines a blocking capacitor with a gas tube, is rated for 50 kA surge current and handles up to 375 W of RF power depending on frequency. It is flange-mounted for grounding and is used on VHF/UHF radio, land-mobile and public-safety antenna lines; for outdoor use it must be sealed with a weatherproofing kit.
Key Features
- Frequency range 125 MHz to 1000 MHz
- N female to N female connectors
- DC block design: blocking capacitor plus gas tube, no DC continuity from center pin to center pin
- Surge current 50 kA (IEC 61000-4-5, 8/20 us waveform); multi-strike capability
- Max RF power 375 W (frequency dependent)
- VSWR < 1.1:1, insertion loss 0.1 dB max
- Ports marked ANTENNA and EQUIPMENT; must be installed in the correct direction
- Not weatherproof: outdoor installations require PolyPhaser WK-1 weatherproofing kit
- CE and RoHS compliant; UL497E
