Comm Antenna

      I'm having a problem with my comm antenna installed in my Europa. 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? 
      
      Thanks

switch for smoke pump
      
      I would like to wire the panel switch to work as follows:
      pump off, pump on and a third position to activate a remote switch to 
      turn the pump on and off. What would be the proper switch to use and how 
      would one wire it?
      
      Thanks
      Jonsey
