I'm having a problem with my comm antenna. It is a common copper tape antenna
with toroids over the coax. Materials and plans came from RST Engineering.
Installed
in the rudder 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). 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.
Have others had difficulity with the dipole in the rudder causing problems?
Found
a solution? How about using other antennas, like Bob Archer?
Thanks
