Regular LNBFs are designed to last only five to seven years. Slowly, a typical DRO LNBF loses performance as the mechanically tuned frequencies slowly drift until one day the receiver is no longer capable of tuning the satellite channels. PLL LNBFs do not rely on a mechanical tuning slug that may shift off frequency due to physical damage or aging. PLL LNBFs have an internal crystal oscillator that will remain tuned exactly on frequency even in the harshest the environmental conditions.
Most LNBFs are not UV rated to protect against prolonged exposure to the sun. Often, the LNBF's white cap becomes brittle and cracks after just a few years and the feedhorn fills with water damaging or shorting out the electronics. The SL1 PLL LNBF feedhorn cap and the case will not fail as it has been tested and proven to resist the effects of 15 years of extreme 24/7 UV exposure! This is equal to over 30 years exposure mounted on a satellite dish!
SL1PLL LNBFs are factory tested and warranted to be completely WaterProof. This means that the SL1PLL LNBF has been completely immersed in water for a ten minute test to insure proper assembly, fitting and component integrity. Most LNBFs are only water resistant or water shielded and are not tested to provide years of continued operation in the most extreme environments.
