The components include (from top left to lower right) the LNA preamps, a NEMA enclosure purchased at our local electrical store along with stainless steel clamps to attach it to our tower, N-type feed-through connectors to pass the feedline connections in and out of the enclosure, a terminal strip for control cable and power connections, hardware to mount the preamps in the enclosure, LMR-240 coax for RF connections inside the enclosure, the M2 Antenna Systems S2 Sequencers, and N-connectors for the LMR-240 coax jumpers. If a dipole antenna is fed with a coaxial cable from the Every BalUn or antenna kit in a. Above the horizon, the pat-tern transforms to RIGHT HAND CIRCULAR, making it a natural for OSCAR satellite use. The EGGBEATER produces smooth Omni directional HORIZONTAL polarity at the horizon. The picture above shows all of the parts and components which make up the LNA preamp system. Eggbeater Satellite Antenna FEATURES: The EB-432 EGGBEATER offers exciting new performance characteristics for both fixed and mobile operations. Home made Eggbeater antenna Hardware Libre Space Community This implies an ideal omni-directional antenna would have an elevation pattern that was -6 dB from 30 degrees to 90 degreesfocusing the gain from the horizon up to 30 degrees elevationwhere you need it the mostbut without the deep overhead null presented by high-gain verticals. verticals, Lindenblad, Quadrifilar Helix, and Eggbeater just to name a few. We also decided to mount the LNAs and associated control interconnect points inside a NEMA enclosure. antenna described here should be adequate to receive signals from the ISS. We chose to use M2 Antenna Systems S3 Sequencers to safely switch the LNAs to bypass during transmit (more on this below). The first is proper sequencing control to ensure that the RF power going to the antennas during transmit does not destroy the preamplifiers and the second is to provide adequate protection from the weather. There are two issues to be addressed here. Mounting electronics on the tower is always a reliability concern.
