Combination of identical antennas, circular polarized cross-yagis or X-Quad-Antennas

Combine two or four antennas by coaxial power splitters. The power splitter serves as an almost loss-less transformer to adapt the 12.5 respect. 25 Ω base impedance of the parallel antennas to the required 50 Ω. A phase harness is required to obtain circular polarization out of a crossed yagi or an X-Quad antenna. The phase harness is located directly at the antenna and consists of various coaxial lengths with varying impedances; thus the harness is responsible for the correct phase difference of the polarization planes and matches the system to meet the 50 Ω impedance of the feed line (remark: just one feed line is required).

A disadvantage of this economic solution is the fact that the polarisation of the antenna is fixed to right-hand circular (RHCP) and cannot be changed any more. In order to change the plane of the polarization one can use a polarization switchbox or our new remote controlled polarization switch. When using the polarization switchbox two cables must be fed from the antenna to the radio shack. A short cable connects the box and the radio; the rotation knob allows changing of the polarization manually. The new remote controlled polarization switch is mounted directly at the antenna feedpoint or close to it under the roof. The remote box is connected to the radio by a coax cable and needs an additional 4-wire DC cable to control the remote box. This setup allows to operate crossed yagis and X-quads in circular as well as horizontal/vertical polarization modes. Feeding up to four independent antennas through just one coax cable is possible with our remote antenna control switches.
