The 436CP16 and 2MCP8A are light weight, circularly polarized antennas optimized for Low Earth Orbit (LEO) Satellite communications or other applications where a small circular polarized antenna is required. Optimum match and gain designed for the satellite band. Rear mounted for easy coaxial cable routing. A preamp can be mounted close to the antenna for almost no coax loss before the preamp, maximizing your receive performance. Computer design techniques help keep spurious side lobes down for optimum signal to noise rations. Both the 436CP16 and 2MCP8A feature the same CNC machined, O-ring and silicone-gel sealed, driven element assemblies common to all M2 Yagi Antennas. This insures years of trouble free performance regardless of weather. We went a step further and designed a custom LEO cross boom to pair these two antennas together for a very manageable amateur satellite ground station.
