The 436CP16 is a light weight, circularly polarized antenna optimized for Low Earth Orbit (LEO) satellite communications or other applications where a small circular polarized antenna is required. Optimum match and gain are between 432 & 440 MHz 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 low down for optimum signal to noise ratios. This antenna features 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 ofweather.
