Installation Instructions

Choose a mounting location that is as high as feasible, as free as

possible from obstructions, and as far as possible from other antennas

and strong sources of RF.

1. Mount the antenna.

For mast mounting, use the antenna’s 2¾”x26” aluminum

sleeve, and strap it directly to the mast with suitable hardware

(not supplied), or use a Shakespeare Style 483 Clamp Set (sold

separately).

For bulkhead mounting, use Shakespeare Style 484 Wall Mounting

Brackets (sold separately).

2. Connect the antenna to your transceiver using suitable coax cable

(sold separately).

IMPORTANT: Do not mount or store this antenna in an inverted

or horizontal position. Always position the antenna so moisture

absorption or condensation can drain out between the aluminum

sleeve and the coaxial connector.

INSTALLATION INSTRUCTIONS

You, your antenna, and safety

Each year, hundreds of people are killed, mutilated, or receive severe

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!

SITE SELECTION

Before attempting to install your antenna, think where you can best

place your antenna for safety and performance.

To determine a safe distance from wires, power lines, and trees:

If you are unable to maintain this safe distance, STOP! GET

PROFESSIONAL HELP. Most antennas are supported by pipe masts

attached to the chimney, roof, or side of the house. Generally, the

higher the antenna is above ground, the better it will perform. Good

practice is to install your vertical antenna about 5 to 10 feet above the

roof line and away from power lines and obstructions. Remember that

the FCC limits your antenna height to 60 feet. If possible, find a

mounting place directly above your set, where the antenna wire can

take a short, vertical drop on the outside of the house for entry through

a wall or window near the set. Your dealer carries a complete line of

installation hardware.

The safe distance from power lines should be at least twice the

height of your antenna and the mast combined.

If you are installing an antenna for the first time, please, for your

own safety as well as others, seek PROFESSIONAL

ASSISTANCE. Consult your dealer. He can explain which

mounting method to use for the size and type of antenna you are

about to install.

Select your installation site with safety, as well as performance in

mind. (Detailed information on the 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.

Call your electric power company. Tell them your plans and ask

them to come look at your proposed installation. This is a small

inconvenience, considering YOUR LIFE IS AT STAKE.

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 to a

specific task and should know what to do and when to do it. One

person should be designated as the “boss” of the operation to call

out instructions and watch for signs of trouble.

When installing your antenna, REMEMBER:

DO NOT use a metal ladder

DO NOT work on a wet or windy day

Increase your personal safety - dress properly - shoes with rubber

soles and heels, rubber gloves, long sleeves shirt or jacket.

If the assembly starts to drop, get away from it and let it fall.

REMEMBER: 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 antennas and the installer - THAT’S YOU!

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 and a victim is in contact with live

wires, DO NOT TOUCH! Move the victim away from contact by

using dry wooden boards, wood broomsticks, dry rope, sheets, or

blankets. If their breathing has ceased, apply artificial respiration.

Have someone call for medical help.

Measure the height of your antenna

Add this length to the length of your tower or mast

Then, double this total for the minimum recommended safe

distance

INSTALLATION OF THIS PRODUCT NEAR POWER LINES IS

DANGEROUS. FOR YOUR SAFETY, FOLLOW THE INSTALLATION

DIRECTIONS.

General Installation Instructions For Mast Mounted Antennas

Assemble your new antenna on the ground at the installation site.

Keep the assembly instructions that come with it separate.

On the ground, clamp the antenna to the mast, pull enough

coaxial cable, and connect it to the antenna.

To insure that a mast does not fall the “wrong way” if it should get

away during installation or takedown, durable non conductive

rope should be secured at each two foot level as the mast is

raised. The boss should stand in a position where he can yank or

pull the ropes if needed to deflect the falling mast away from

hazards (such as power lines) into a “safe fall” (such as a

driveway). The ropes are tied taut at the base of the mast after

installation and in place at the various levels.

Install the selected mounting bracket.

If you are going to use the guy wire installation instead of a

mounting bracket:

• Install guy anchor bolts

• Estimate length of guy wire and cut

• Attach a mast using guy ring

Carefully take the antenna and mast assembly to the mounting

bracket and insert. Tighten the clamp bolts. In case of guyed

installation, it will be necessary to have at least a second person

to hold the mast upright while the guy wires are attached and

tightened to the anchor bolts.

Install self-adhering “DANGER” label packed in the antenna

hardware kit at eye level on your mast.

Install a ground rod to drain off static electricity build up and

connect the ground wire to the mast and ground rod. Use special

ground rods and not a spare piece of pipe. (See “Example of

Antenna Grounding”.)

Drill a hole in the wall (CAREFUL! There are wires in that wall!)

near set just large enough to permit entry of the cable.

Push the cable through the hole and form a rain drip loop close to

where it enters the house.

Put a small amount of caulking around the cable where it enters

the house to keep out drafts.

Install static electricity discharge unit.

Connect the antenna cable to set.

For tripods, Telescoping Mast, or

Towers, refer to manufacture’s

installation instructions (Water

pipes are not a suitable mast for

antenna installations.)

There are three types of

supporting structures commonly

used in antenna installations.

these and various mounting

methods.

EXAMPLE OF ANTENNA GROUNDING AS PER

NATIONAL ELECTRICAL CODE INSTRUCTIONS

Use No. 10 AWG copper or No. 8

AWG aluminum or No. 10 AWG

copper-clad steel or bronze wire or

a larger ground wire for both mast

and lead-in. Securely clamp the

wire to the bottom of the mast.

Secure lead-in wire from the

antenna to the antenna discharge

unit and the mast ground wire to

the house with stand-off insulators

spaced from 4 to 6 feet (1 to 1.83

Meters) apart.

Mount the antenna discharge unit

as close as possible to where the

lead-in wire enters the house.

Suitable grounding electrode driven

8 feet into the earth (CAUTION:

Avoid underground power cables

and gas lines)

TRIPOD

ROOF MOUNTING

The swivel feature of “universal” type mounting brackets makes a

convenient antenna mount for flat or peaked roofs. One clamp type

bracket is used with 3 or 4 guy wires equally spaced around the mast

and anchored to the roof or eaves by eyebolts. Apply roofing

compound around the base of the bracket, screws and eyebolts for

moisture sealing.

The safe distance from power lines should be at least twice the

height of your antenna and the mast combined.

The safe distance from power lines should be at least twice the

height of your antenna and the mast combined.

CHIMNEY MOUNTING

The chimney is often an easy and convenient

mounting place. But the chimney must be

strong enough to support the antenna in high

winds. Do not use a chimney that has loose

bricks or mortar. A good chimney mount makes

use of a 5 to 10 foot 1-1/4” diameter steel mast,

and a heavy duty two strap clamp-type bracket.

Install the upper bracket just below the top

course of bricks, and the lower bracket 2 or 3

feet below the upper bracket. For maximum

strength, space the brackets as far apart as

possible.

Note: Guy wires are highly desirable on

chimney mounts.

SIDE OF HOUSE MOUNTING

Where roof overhang is not excessive, the side

of the house provides a convenient mounting.

Position the brackets over a stud if possible,

one above the other, and space 2 or 3 feet

apart. For metal siding, first mark mounting

holes, then drill pilot holes through the siding to

accept mounting screws.

(CAREFUL! There are wires in that wall!)
