摘要
结合实际，从理论分析的角度，探讨了仅在有线电视系统的前端，通过选择电视接收天线的方向、架设高度和位置以及采用差值接收天线和加强接收天线的屏蔽等办法来抑制电视同频干扰的问题．
The restraint of cable TV common-frequency interference has been a tough problem in cable TV technology. Based on theoretical analysis and on practical working experience, a solution to the above problem is presented with the following methods:(1) Adjusting the direction,height and location of the receiving antenna ;(2) Adopting the D-value receiving antenna ;(3) Strengthening shielding of the receiving antenna.
