The problem I see is that yes, the fuel tank will serve as a good ground
plane, but mounting the antenna this way will result in a horizontal
polarization of your signal. That is, the stuff that gets squirted out will
be vibrating to and fro rather than up and down. Everybody elses' radios
are expecting up and down and won't work too well with the to and fro.


Hmmm??
Well there's an idea. If I mount the antennae to the BOTTOM of the fuel
tank...

Everybody else is expecting up and down, but I'll give them down and up.
I generally get ATC commands all backwards anyways, so this would be a
way to reverse them BEFORE they get to me...which when I get them
backwards, it will actually be forwards. I'll still be a royal ****-up,
but now no one will KNOW about it!

wouldn't reversing the antenna along the Z axis merely have the effect of
changing a ****-up to a ****-down, royal or otherwise?
