OMS-λ/4N-JK/0825,800-2500MHz,40KA,DC Block,1/4 Wave Antenna Surge Protector,Antenna Surge Protector,Base Station Antenna Surge Protector
Product Description:
OMRDON OMS-λ/4N-JK/0825 high-frequency coaxial antenna lightning protector (SPD, surge protector) is the use of 1/4 wavelength-type short-circuit rod filtering principle, is a new type of surge protector, which is widely used in the frequency is relatively high, and the frequency band is relatively fixed on the radio equipment, the main advantages of its lightning protection effect is obvious, the impact of the current withstand is particularly large; the signal of the Insertion loss is small, λ / 4 high-frequency coaxial lightning protector can also greatly inhibit the interference of different frequencies; these features are related to its unique principle and structure. Suitable for satellite wireless communications mobile base stations, microwave communications, radio and television coaxial antenna feeder system signal surge protection is installed in the lightning protection zoning LPZ 0 A-1 and subsequent zoning.

Installation Notes:
- This series of lightning protectors does not distinguish between input and output terminals, any port can be connected to the protected equipment;
- The closer the lightning protector is mounted to the front of the protected equipment, the better the result;
- The equipment needs to be inspected regularly and the product must be replaced immediately after deterioration;
- Grounding must be good, and it is recommended that the grounding resistance be no greater than 4 ohms.
