Omrdon Technology 
OMS-DIN/3850, 380-512MHz,1/4波天馈避雷器，DC Block，3000W, 50kA, 大功率射频广播/雷达天线电涌保护器
Product Description:
欧姆雷盾（OMRDON） OMS-DIN/3850射频同轴天馈防雷器（SPD、电涌保护器）是采用1/4波长型短路杆的滤波原理，它广泛应用于380-512MHz频段相对固定的无线电设备上，其主要优点是防雷效果明显，冲击耐流特别大(50KA)，对信号的插入损耗小。λ/4高频同轴防雷器还能大大地抑制不同频率的干扰；这些特点均与其独特的原理和结构有关。适用于卫星无线通信移动基站，微波通信，广播电视等同轴天馈系统信号的电涌保护安装于防雷分区LPZ 0 A-1及后续分区。

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.
