We recommend replacing your GEOSATpro LNBFs SL1PLL about every 5 years. Our single output LNBF's offers high stability, high gain, yet low noise. It allows reception of Ku-band signals with the highest possible signal level and quality. Fits any standard Ku-band satellite dish with a 40mm universal LNBF mount. Use this with your Free To Air (3ABN, SDAdish or Adventist channels satellite system) receiver for excellent and superior Ku-band reception. This LNBF will outperform most 0.3dB LNBFs on the market! I recommend always having a spare on just in case electrical storms damage you working LNBF, we can ship up to 4 LNBs for the same shipping cost.
