Introduction
Thank you for purchasing the Alpha Sky Antenna, a complete 1KW satellite
antenna system. The Alpha Sky Antenna system is designed to be used for
Mobile, Portable Temporary Emergency Deployment, Field Operations,
Apartment/Condo Residents, or HOA's.
The Alpha Sky Antenna System is a Circularly Polarized Omni directional
antenna. The Alpha Sky Antenna makes for an excellent portable, base, or
mobile antenna. The Alpha Sky Antenna system works for satellite
communications plus repeater or non-repeater communications. The antenna
system achieves and SWR of less than 1.5:1 on 2 Meters, as this is the band that
transmission to satellite occurs. SWR is a little higher on 440MHz and this
antenna should not be used to transmit on this band. The antenna system can be
used without a duplexer directly into an HT or other rig. As you can see in the
online videos, this antenna does not require a preamp to work the satellites.
Alpha Antenna uses antenna designs that are known to work! Designed by
Amateur Radio Operators at Alpha Antenna, in conjunction with a Certified
Commercial Broadcast Engineer, the Alpha Sky Antenna uses the best antenna
designs in one antenna system.
Technical Specifications
Weight: 5 pounds
Configuration: Omni-directional & Circularly polarized
Frequency Coverage: 140-148 MHz XCV & 420-450 MHz RCV
Power Rating: 1KW
Height: Approximately 13 Inches in circumference
EITHER
o Magnet Mount adds 2 1/2 inches in height
We do not recommend driving with the antenna mounted on
the mount
OR
o Counter-poise system adds 2 feet. Tripod optional.
IMPORTANT! All components of the antenna system are designed to work
together to keep SWR low. Use components separately at your own risk.

Installation Safety
WARNING: INSTALLATION OF THIS PRODUCT NEAR POWER LINES IS
DANGEROUS! FOR YOUR SAFETY, FOLLOW THE ENCLOSED
INSTALLATION DIRECTIONS. THOUGH THIS ANTENNA IS CONSTRUCTED
OF INSULATED WIRE, PROPER CARE MUST
BE TAKEN DURING INSTALLATION. INSTALLER ASSUMES ALL LIABILITY
FOR PROPERTY AND LIFE SAFETY.
YOU, YOUR ANTENNA, AND SAFETY
Each year, hundreds of people are killed, mutilated, or receive severe and
permanent injuries when attempting to install an antenna. In many of these
cases, the victim was aware of the danger of electrocution, but did not take
adequate steps to avoid the hazard. For your safety, and to help you achieve a
good installation, please READ and FOLLOW the safety precautions below.
THEY MAY SAVE YOUR LIFE!
1. If you are installing an antenna for the first time, please, for your own safety as
well as others, seek PROFESSIONAL ASSISTANCE.
2. Select your installation site with safety, as well as performance, in mind.
(Detailed information in Site Selection appears in a separate section of this
booklet.) REMEMBER: ELECTRIC POWER LINES AND PHONE LINES LOOK
ALIKE. FOR YOUR SAFETY, ASSUME THAT ANY OVERHEAD LINES CAN
KILL YOU.
3. Call your electric power company. Tell them your plans and ask them to come
take a look at your proposed installation. This is a small inconvenience,
considering YOUR LIFE IS AT STAKE.
4. Plan your installation procedure carefully and completely before you begin.
Successful raising of a mast or tower is largely a matter of coordination. Each
person should be assigned a specific task, and should know what to do and
when to do it. One person should be designated as the leader/coordinator of the
operation to call out instructions and watch for signs of trouble.
5. When installing your antenna, REMEMBER: DO NOT USE A METAL
LADDER. DO NOT WORK ON A WET OR WINDY DAY. DO DRESS
PROPERLY: shoes with rubber soles and heels, rubber gloves, long sleeved
shirt or jacket.
6. If the assembly starts to drop, get away from it and let it fall. Remember, the
antenna, mast, cable and metal guy wires are all excellent conductors of
electrical current. Even the slightest touch of any of these parts to a power line
completes an electrical path through the antenna and the installer – THAT’S
YOU!
7. If ANY PART of the antenna system should come in contact with a power line,
DON’T TOUCH IT OR TRY TO REMOVE IT YOURSELF. CALL YOUR LOCAL
POWER COMPANY. They will remove it safely. If an accident should occur with
the power lines, call for qualified emergency help IMMEDIATELY.

Antenna Assembly & Installation
Step 1 – Assemble
antenna with the included
hex wrench. **Do not
assemble over carpeted
floors, outdoors, or where
any surrounding surface
might lose small parts.
We are limited on extra
parts to replace lost parts.
MAGMOUNT OPTION Step 2 – Install the
Magnet or Lip mount on
your vehicle or above
another large metal
surface so that low SWRs
are maintained and more
of the satellites signal can
be reflected back towards
the antenna.
MAGMOUNT OPTION Step 3 – Screw the Alpha
Sky into the mount.
COUNTER-POISE
OPTION - Step 2 – Mount
the Alpha Sky Antenna
sphere on the CounterPoise System. Install your
mount with 24x3/8 female
adapter on your mast,
tower, etc.
COUNTER-POISE
OPTION - Step 2 – Screw
the entire Alpha Antenna
System onto your mount.
We’ve mount options
available for towers,
masts, etc.

SWR Performance
The SWR on the Alpha Sky Antenna system comes pre-set from the factory.
Once you assemble your new antenna system, you will notice that it has no more
than a 1.5:1 on 2 Meters, as this is the band that transmission to satellite occurs.
SWR is a little higher on 440MHz and this antenna should not be used to
transmit on this band.
