The included universal flat type three ring scalar is tapped for mounting on button hook, three and four leg prime focus dish designs.Important Notice: The "0" Zero skew stamp is aligned with the horizontal polarity probe.

Review: Entrega rápido. Bien embalado. Funciona perfecto.
Review: It actually worked. - We ordered one since we were getting lots of interference on 58w and after installing this LNB all is back to normal. Little pricey in comparison to what it was 2 years ago but as long as it's works, I am happy.

A: The C238 is a LNBF with 3800-4200MHz bandpass filter.

**Q: this C-Band lnb work in kuwait ?**
A: LNBFs will work anywhere, but they are either wideband with no frequency filtering or only pass a portion of frequencies to pass and may also include additional filtering outside of the bandpass.

Compare the frequencies of the transponders that you wish to receive and make sure that the LNBF that you purchase, provides band pass through for these frequencies.
