OMS-DIN/3851, 380-512MHz,1/4 Wave Antenna Surge Protector, 3000W, 50kA, DC Block, RF Broadcast Antenna Surge ProtectorCan penetrate walls
Product Description:
OMRDON OMS-DIN/3851 RF coaxial antenna lightning protector (SPD, surge protector) is the use of 1/4 wavelength-type short-circuit rod filtering principle, which is widely used in the 380-512MHz band relatively fixed radio equipment, its main advantages are lightning protection effect is obvious, the impact of the current withstand is particularly large (50KA), the insertion of the signal is small loss. λ /4 high-frequency coaxial lightning protection 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.
