The general trailing antenna have some disadvantages, such as large noise, low efficiency and shallow communication death so on.
常规拖曳天线通信存在噪声大、效率低及通信深度浅等缺点，从而严重影响潜艇战斗性能的发挥。

Antenna have high gain, lownoise temperature characteristic under test in experimentation, and it can precision tracking at S-band, high efficiency receive at S/X-band.
