Please assure that you are familiar with this product before you buy, because the manual we offer is Chinese.
This one sells at a price of $ 14.54.
SF-95DR has a blue back light to allow use at night. The signal meter never needs to be recalibrated nor does it need complicated programming. It automatically recognizes the LNBF frequency and works with any C band, Ku band, or Ka band satellite. No need to input transponder frequency, symbol rate, or polarity. Truly plug & play.
It only costs you $ 12.55.
