GENERAL DESCRIPTION
This Wind Cone fixture is an 18-inch diameter by 8-foot long nylon wind sock mounted on
a cylindrical framework attached to a pipe support by two bearing assemblies. The Wind
Cone comes with a red obstruction light, four PAR 38 lamp holders mounted on the main
support and a frangible coupling on the lower end of the main support shaft. The entire
assembly is mounted on a base plate or rigid steel conduit elbow which is supplied by
others.
2.0
GENERAL APPLICATION AND REQUIREMENTS
The type L-806 is designed to indicate wind direction at airports.
The wind cone fixture should be mounted in a location near the runway to give a true
indication of wind velocity and direction. The cone assembly is designed to move freely
about the vertical shaft to indicate the true direction of the wind for velocities in excess of
three miles per hour.
The lighting fixture assembly consists of four PAR 38 lamp holders spaced equally in a
plane above the fabric cone to provide the horizontal candlepower values required by F.A.A.
specification L-806.
3.0
WIND CONE SHAFT
The main vertical support of the wind cone fixture is constructed of extra heavy 1-inch steel
pipe. A frangible coupling is provided at the bottom of the main vertical support.
4.0
CYLINDRICAL SUPPORT AND BEARINGS
The cone support consists of a tapered cylinder attached to the two ball bearings on the
vertical support by means of two strap arms. A clamping ring is furnished for attaching the
fabric cone to the inner end of the support. Each of the two bearing assemblies consists of a
heavy duty ball bearing enclosed in a weatherproof housing. Alemite grease fittings are
provided for lubrication.

5.0
FABRIC CONE
The cone is fabricated of water-proof white or orange nylon fabric in the shape of a
truncated cone, 18 inches in diameter at the throat, 8 inches in diameter at the other end and
8 feet long.
6.0
JUNCTION BOX AND OBSTRUCTION LIGHT
A type GRF fitting at the top of the vertical support serves as a support for the four PAR 38
lamp holders (or four horizontal arms, for reflector floodlights (-RF Option)), a wiring
junction box and has a cover with hub to which the EOL, L-810 is attached per spec. The
obstruction light fitting includes a standard type red prismatic globe as used on type EOL
marker lights, and a lamp receptacle for a 116 watt 120 volt, A-21 clear bulb, medium screw
base traffic signal lamp.
7.0
LIGHTING UNITS
Four PAR 38 lamp holders are provided for illuminating the wind cone. Fixtures are
arranged for 250 watt, 120 volt, bulb, medium screw base lamps. Lamps and lamp holders
are adjusted for a 60° angle off the vertical (see Figure 1).

INSTALLATION ON GROUND
Where the wind cone is to be installed near a runway, FAA specification L-806 requires that
it shall be mounted on a frangible coupling.
10.
WIRING
Power required for the lighting on the wind cone is 120 volt AC or DC. Internal wiring
utilizes #14 AWG THWN single conductor type wire. Voltage drop from the transformer
vault to the wind cone should be held within 5% of line voltage by using wire of sufficient
size. If the wire run from the transformer vault to the wind cone is exceptionally long, it
may be more economical to utilize wires of a smaller size with a voltage booster
transformer.
Wires from the transformer vault may be brought up through the frangible coupling
threaded into the base, and brought up through the inside of the pole to the condulet junction
box at the top of the wind cone fixture. Access to the condulet junction box for wiring is
obtained by removing the hub cover which requires the removal of four screws. Splices of
the wires from the base of the standard to the four individual lighting fixtures should be
made in the junction box.
11.
GROUNDING
This installation is to be grounded in accordance with FAA specification L-107
requirements.

12.
LUBRICATION
The wind cone bearings are factory lubricated. Approximately once a year lubricate the
bearings (each bearing housing is provided with an Alemite grease fitting) with Exxon
Beacon #325 grease, or equivalent low temperature high quality silicone grease.
NOTE
Local environmental conditions may require more frequent lubrication.
WARNING
If at any time the wind cone does not rotate freely (in a 3 MPH or higher wind), thoroughly
clean and relubricate the bearings. If the bearings are worn, so that there is binding at any
point, replace both bearings immediately.
