我发现WILSON WEBOOST 311155 能增强信号,但也不多,大概5-10db。
ebay上有买的,听说50ohm的笔75ohm好。我买的是75ohm的。 |

x******h 发帖数: 838 | 2 对速度有影响吗?后来终于发现插26频插口信号好些,但速度没变化,本来就有2格变3
格,强个10db的模样。
天线说适合2300-2400,2500-2600,难道对41无效?41是2.5g,刚好是用24xx然后没用?

termination卖,不过你现在已经不需要了。

实际上monoprice上价钱很便宜,就是那个shipping讨厌 |

J********o 发帖数: 17447 | 7 大神在这里看到你了~我刚搞了er4p正准备搞个fiio E17, 你这样说我很欣慰呀哈哈
ER4P价格75ohm变4s加E17会不会更好些? |

that much capacitance will be very difficult to drive at high speed. the
typical approach is to use a high current amplifier, and to use a serial
resistor (50 - 75ohm) to dampen the capacitance.
you may want to look into how ADSL modems solve such problems: though
the load there is more inductance than capacitance.
and they can achieve very high speed. |

用一条BNC的cable 就和示波器相连了。当然示波器的阻抗输入可能也是标准的估计不
是50ohm就是75ohm的。 |
