It is a common copper tape antenna with toroids over the coax. Materials and plans came from RST Engineering. Installed in the vertical rudder fin per Europa directions and tuned using a SWR bridge. When I transmit, certain frequencies cause my ACK ELT to transmit. It is located on the bottom of the fuselage touching the rear bulkhead (under the elevator torque tube). This is about 20 inches forward of the antenna and near the tip of the copper tape. If I disconnect the cable going to the remote actuator, there is no problem. (I had this problem previously and added toroids to the four wires but no change). Also, when I transmit, certain frequencies cause the magnetometer in my GRT EFIS to swing heading 20 degrees. The magnetometer is mounted on the port side of the fuselage essentially on the fuselage parting line and just at the rear of the D panel bulkhead. This is about 60 inches forward of the antenna and about aligned with the center of the copper tape. Have others had difficulity with the dipole in the rudder causing problems? Found a solution? How about using other antennas, like Bob Archer?

What would be the proper switch to use and how would one wire it?
