![]() ![]() It also uses, optionally, a pair of parasitic reflector elements to focus more of the radiation pattern overhead. The garden-variety home-brew version employs a 90-degree "phasing" line to provide a fixed right-hand circular polarization (RHCP). Commercial versions are available from M2 Antennas. It is, basically, just two full wave loops fed in quadrature. Background: The "eggbeater" antenna is an omni-directional antenna employing circular polarization to maximize signal capture from low Earth orbit (LEO) satellites. This design is the outcome of my investigations into methods of improving the performance of the "original" eggbeater without obviating the simple construction. I have built several of the traditional "eggbeaters" from plans floating around on the Internet, but was never satisfied with the overall performance. 1 of 5 Eggbeater II Omni LEO Antennas Presented here is a high-performance, circularly polarized omni-directional antenna that is easy to build, easy to tune, inexpensive, and will work all the mode J Low Earth Orbit (LEO) satellites. ![]()
