This cross polarized Yagi was computer designed for the serious OSCAR user. The average side and back lobes power have been reduced by approximately 10 dB over any previous design, enhancing signal to noise ratio and putting all your power where it will do the most good. The 2MCP22 is ideal for general use over the ENTIRE two meter band from FM to SSB and CW DX. Arrays of two or more will even permit moonbounce contacts using the old reliable passive repeater in the sky. The unique Driven Element Modules are CNC machined and feature O-ring sealed connectors. Internal connections are encapsulated in a space age silicone gel with nearly 4 times the dielectric strength of air. The 2MCP22 is our finest circular polarized antenna. We are confident you will be impressed with the 2MCP22 from the moment you open the box until you've worked DXCC and beyond! Optional items include HDFG fiberglass crossboom kit compatible with Yaesu 5400 and 5600 series az-el rotators, power dividers 2M2PORT and 2M4PORT, polarity switch, phasing lines VHF-50-2MCP22(2) or (4), ‘H’ frames, OR-2800 azimuth and MT-1000 and MT-3000 elevation rotators / positioners.
