feet and have had no issues.
“The installation is comprised of
common materials. The white tube
through the fuselage is 1/8-inch [outside]
diameter (OD) x 1/16-inch [inside]
diameter (ID) styrene plastic tube from
the train section of a local hobby shop.
I encased the antenna lead in 1/16-inch
heat-shrink tubing, then reamed the
tubing with a 1/16-inch drill for a snug,
but slip, fit.
“I chamfered the ID of the inside of
the tube to ease antenna insertion in the
tube and installed them in the fuselage
at a 45° angle to the fuselage centerline.
The white heat shrink on the antenna is
a stop to ensure the active portion of the
antenna is totally outside of the carbon-fiber fuselage.
“It is now a simple matter to install
the antennae when assembling the
airplane at the field. When you are
finished flying and packing up, it’s
also a simple matter to remove the
antennae and stow them under the
canopy, free from potential damage.”
I am using a Spektrum radio with a
satellite receiver that provides a third
antenna for redundancy. Using Mark
Williams’ installation method, the third
antenna can exit through a tube in the
canopy. Whatever radio you use, the
important thing is to get each of the
31mm antenna ends outside of the
Mark’s method does that with the
added benefit of being able to retract the
antennae for storage. Thanks, Mark.
