Question: 75cm dish + c band LNB = 115.5 china 6b?

general_lee31

I had brought some stuff for receiving satellite TV from china which was for 146 in ku band.

Now I want to use it to receive 115.5 china 6b.  I know that some people in china use small dishes (75cm or 90cm)with C band LNB and a 高效馈源 to receive 115.5.  it that possible in AU?

I would like to try it and I will need a C band LBN and a 高效馈源. anyone has a spare one?

Thanks

我所知道澳洲要收115的dish应该至少1.5m

75太小了
不过你既然都买了，可以试试，就当做个实验吧。

不光是大小的问题 是偏馈ku天线 基本上不会有什么太好的效果  偏馈天线目前还能服役的是1.2m的还需要用高效馈源对于diy过于麻烦了   146在国内的信号相当强 ku锅用45cm的就够了 这个75的看来是一锅多星的材料 lz如果真的需要用这个天线调试 需要多用点时间了

Thanks tears.  if you mean there is possibility to receive 115.5 with the 75cm?

because my back yard is very small so i have to try smaller dish and i don't want to waste the 75 dish.

do u know where can i buy C band LBN and 高效馈源?  better to have a second hand one to try.

有人做过实验90cm的加高效馈源可以收几个台。

高效馈源要到ebay找了，50美金，搜Conical Scalar Feed，国内倒是便宜50rmb。

这个75cm的实在不值得再多花钱了 先试试吧 如果能收到几个台再试试加馈源 否则太浪费了
