If you're a regular visitor of radio fleemarkets, you've surely noticed the growing number of second hand lnb's being offered. One of them is called Bluecap. Seeing the picture below, its name is no surprise. Ten years ago they were sold with nearly every satellite dish, especially in the UK. Nowadays you can buy them for the price of a glass of beer.

LNB's without a build-in feedhorn are generally the oldest and easiest to rebuild. These old LNB's are only capable of receiving the lower band. The local oscilator works on 9.75 GHz. If you change the LO frequency to 9 GHz, the entire 3cm band will range from 1000 to 1500 MHz.
