My Terra radio installation instruction says "Porper attachment of any
antenna to the aircraft surface is of primary importance. Carefull
clean all paint and corrosion off the mounting surface and apply an
anti-corrosion treatment."

Question 1, does "clean all paint" mean strip all paint to bare
aluminum?

Question 2, what type of "anti-corrosion treatment" should I use?

Thanks in advance,

Robin Hou

The antenna MUST have a good electrical contact with the aluminum, in
order to have a ground plane. You might get by if you strip the aluminum
at the bolt holes on the inside of the aircraft, as the ground gets
contact through those bolts.

Alodine is a good anticorrosion treatment. Be sure to make provision to
keep any water away from the antenna/airframe contact.
