Omrdon Technology 
OMS-F-JK/3.0.OMS-F-KK/3.0, F type cable TV antenna lightning arrester, switching type antenna lightning arrester, antenna lightning arrester
Product Description:
OMRDON (OMRDON) antenna feeder surge protector with F-type connector, can prevent the feeder from inducing lightning overvoltage and damage to the antenna and transceiver equipment, suitable for CCTV video surveillance, CATV cable TV, Wireless TV wireless TV and other coaxial antenna feeder system signal surge protection, installed in the lightning protection sub-district LPZ0A-1 and the subsequent sub-districts.
The product is encapsulated in a shielded case with a built-in high quality high-speed overvoltage protection device, which provides efficient protection and defense against lightning high-voltage pulses induced on the antenna feeder line.

- Maximum output power 400W
- Frequency range DC-3.0GHz
- F-type connector metric/imperial optional, male/female (female to male), female/female (female to female)
- Extremely low VSWR <1.2:1
- Characteristic impedance 50Ω/75Ω
- International Certification RoHS, CE, FCC
typical application::
- CCTV Video Surveillance
- CATV cable
- Wireless TV

Installation Notes:
1, in order to reliably prevent lightning strikes, can be in the antenna output and the input of the protected equipment are connected in series with an antenna feed lightning arrester the antenna feed lightning arrester is not divided into input and output, the interface can be matched.
2, the lightning protector on the lug welding as short as possible grounding wire (wire area of not less than 4mm) 2), the other end is reliably connected to the lightning protection system grounding bus, and the grounding resistance is not more than 4Ω.
3, the product has a waterproof function, but in the outdoor use of the antenna feeder should also pay attention to rain, do not let the rain soak into its internal corrosion damage.
4, this product does not require special maintenance. When the system works faulty, you can remove the lightning protector and then check, if the system returns to normal after restoring to the state before use, it means that the lightning protector has been damaged and must be replaced immediately.
