Dual polarization antenna

A passive dual polarization antenna for an aircraft, for receiving and transmitting high frequency radio signals in the 2-30 MHz band, said aircraft having a generally horizontally oriented surface and a generally vertically oriented surface, said dual polarization antenna comprising:

• a horizontally polarized component;
• and
• a vertically polarized component, said horizontally and vertically polarized components being formed of an integral conductive element having a bend therein such that said horizontally and vertically polarized components have an angular orientation with respect to one another;
• said horizontally polarized component being adapted to be mounted on said generally horizontally oriented aircraft surface and said vertically polarized component being adapted to be mounted on said generally vertically oriented aircraft surface;
• wherein said antenna is an open type electric field antenna, being electrically insulated from said aircraft.

A helicopter comprising:

• a generally horizontally oriented tailboom;
• a generally vertically oriented vertical stabilizer;
• and
• a passive dual polarization antenna, for receiving and transmitting high frequency radio signals in the 2-30 MHz band said antenna comprising:
• a horizontally polarized component;
• and
• a vertically polarized component, said horizontally and vertically polarized components being formed of an integral conductive element, said integral element having a bend therein such that said horizontally and vertically polarized components have an angular orientation with respect to one another, said horizontally polarized component being adapted to be mounted on said tailboom and said vertically polarized component being adapted to be mounted on said vertical stabilizer;
• wherein said antenna is an open type electric field antenna, being electrically insulated from said helicopter.
