【摘要】Huludao' s radio and television digital microwave transmission system has the characteristics of full microwave transmission, broadband digital packets and dual main transmission characteristics. In the launch of MMDS coverage system, the cost has been reduced and the reliability has been improved for BT26elliptical waveguide has been replaced by physical foaming cable. Using an integrated methods of lightning protection, the system's lightning resistance level has been improved. By actual operation test, the system is stable and reliable.%葫芦岛市广播电视数字微波传输系统,具有全程微波传输、宽频带多数字包和双路主备传输的特点；在MMDS发射覆盖系统中,用物理发泡电缆代换BT26椭圆波导,降低成本提高了可靠性；采用综合方法防雷,有效提高了整个系统的抗雷击水平.经实际运行考验,系统稳定可靠,效果很好. 【总页数】4页(75-78)
