摘　　要：我台率先完成了全频段发射天线与双馈系统和开关板进行组合的技术改造实例,这样使得其中的半副天线阵列发生故障时,可以通过开关板切换至无故障的另半副天线阵列上进行工作,为广播电视的不间断和安全播出工作提供了可靠的安全保障。Our station took the lead in completing the technical transformation example of the combination of the full -bandtransmitting antenna with the doubly-fed system and the switch board, so that when the half-pair antenna array was broken down,The switch board can be switched to the other half of the antenna array without fault, which providesa reliable security for the uninterrupted and safe broadcast of radio and television.
