LNB

There may be polarisation rotation scale on the LNB feed horn throat.

那里也许是极化自转标度在LNB饲料垫铁喉头.

Satellite TV receiving antenna LNB regarding the certain receiving system in theoretically is a fixture, but in fact its value is drift because of receiving the working conditions change.

卫星电视接收天线LNB的本振频率对于一定的接收系统在理论上是一个固定值，但实际上其值受到工作环境变化的影响会出现漂移；

CONCLUSION: BPB+ LNB is a better treatment for frozen shoulder in clinic, and SGB and SNB can be used selectively in particular clinical situation.

结论：BPB+LNB是临床治疗肩周炎较好的方法，SGB，NSB可根据临床症状选择性应用。

The more good quality of the LNB, the smaller caliber and the lower cost of receiving antenna were required.

高频头质量越好，相应的接收天线口径要求越小，成本越低。

LNB Frequency Variation and Emergency Measures Along with Environment

Then the LNB is manufactured, and the gain and the noise figure are measured by noise meter. The best scheme is determined with testing and modifying again and again.

通过噪声仪测量LNB噪声和增益，并反复调试和修改，确定最优方案。
