Я люблю летать
Здравствуйте,столкнулись с такой проблемой:приобрели маяк, AK-451 но неизвестно как его устанавливать, инструкция естественно на английском.. и переводиться сама отказывается... Никто не поможет? я впринципе нашел..если подскажите,то ли это,буду признателен..
А может кто сможет поделиться личным опытом по установке,да рассказать что где и как....
2.2.2.2.2 Rod Antenna Installation: (AK 451.017-2A)

The AK 451.017-2A Rod Antenna delivers optimum performance only when installed
correctly. To ensure adequate structural strength of the aircraft for associated air
loading during flight, use of a backing plate or doubler (not supplied) may be
required. Refer to FAA Advisory Circular 43.13-2B for guidance. It is the
responsibility of the installation agency to determine the appropriate and adequate
antenna installation. The AK 451.017-2A Rod Antenna is designed to provide ELT
transmissions from a single BN
C Female coaxial connector.

Location:

The AK 451.017-2A Rod Antenna must be mounted on the top of the aircraft to
assure maximum visibility of satellites (406 MHz). The best location is the upper aft
portion of the fuselage. It should be mounted vertically and away from projections
such as a propeller, tail surfaces, or the shadow of larger antennas.

Installation Preparation:

1. Prepare the surface for an
tenna installations in such
a manner to ensure a ground
contact of less than 0.003
[ch8486]
. If bare metal surfaces are needed for surface
preparation they should be treated with Alodine® 1200 (or similar application) to
eliminate aluminum oxidation. NOTE: The AK 451.017-2A Rod Antenna bonds
through the base plate, not through the mounting screws.

2. Use the AK 451.017-2A outline drawing on Fig. 7 to determine hole pattern and
drill size.

Type of aircraft:

The AK 451.017-2A Rod Antenna is designed for installation on fixed wing subsonic
aircraft with reciprocating or turbine engines and is rated for a maximum airspeed of
350 KTAS (Knots True Airspeed at 25,000 feet).

Installation:

1. Metal adapter plates are optional but th
ey should be used if the curvature or
compound radius of the aircraft skin is such that antennas cannot be directly
installed vertically with their plates mounted flat to the aircraft outer surface.

2. Backing plates or doublers should be installed to ensure adequate structural
strength for associated air loading during
flight. Refer to FAA Advisory Circular
43.13-2B for complete information.

3. Mount the antenna using four 100° countersink #8-32 stainless steel machine
screws and associated hardware. Tighten to 20” lbs max.
 
Installation:

1. Mounting the Blade antenna using #10-32
SS machine screws and associated
hardware and torque to 20 in-lbs.

2. For BNC connector, drill a 0.6250” (5/8”) diameter hole.

3. The most important in installing Blad
e antenna is the electrical bonding
between the base plate antenna and the ai
rcraft skin (metal-to-metal) rather
than thru the mounting screws as some other antennas.

4. A layer of anti-corrosion bonding grease should be applied between the aircraft
skin and the base of the antenna.

5. Metal adapter plates are optional but th
ey should be used if the curvature or
compound radius of the aircraft skin is such that antennas cannot be directly
installed vertically with their plates mounted flat to the aircraft outer surface.

6. Backing plates or doublers should be installed to ensure adequate structural
strength for associated air loading du
ring flight. Refer to FAA Advisory
Circular 43.13-2B for complete information.

7. Remove the 1/2-28 hex nut and external tooth lock washer from the base of the
antenna. Insert antenna connector through mounting hole, make sure the "O"
ring remains in the base of the antenna connector flange groove and that the
connector has sufficient
clearance through the aircra
ft skin. To mount the
antenna, place the lock washer and the hex
nut on the inside of the aircraft and
sandwich the aircraft skin between the base of the antenna and lock washer
followed by the hex unit. Tighten the hex nut to between 25 to 30 in-lbs.

8. Apply a small, smooth fillet with RTV sealant around the periphery of the
antenna base to seal of moisture.

9. For maximum signal strength, the length of the antenna coax to the ELT should
be as short as possible (use of the standard 6-foot coax is recommended when
possible).
