 Posted: Tue Feb 26, 2019 1:41 pm Post subject: Antenna Questions |
 |
|
No. 1: Will a handheld rubber ducky antenna suffice for airport traffic use?
No. 2: Can an external antenna be mounted 2-3ft from the engine?
No. 3: If mounted on Lexon, does the antenna need a ground plane, & if so, how large should it be & would the ground plane need to be grounded to the air frame?

Thanks for the replies.
I found out that all our antennas need a ground plane, as it is the other half of the dipole antenna. It can be the airframe itself grounded to the antenna, or a sheet of aluminum, or even sticky-back copper foil tapped to lexon in the form of 4 to 8 spokes that have a radius equal to the length of the antenna (shorter works but not as good.) They need to be soldered at their intersection. Craft stores carry the foil tape.
