machine work. The design has been optimized for maximum performance and
durability. Altering or modifying the antenna is not recommended.

This packet contains basic assembly instructions for the KLM 160-V antenna.
Also included are the specific dimension sheet, assembly drawing and parts list for

the particular model KLM antenna listen above.

I. PREASSEMBLY

Select an assembly area large enough to accomodate element
Lengths. A shallow box is handy for holding and sortine the small
Hardware. The following tools are required: tape measure, screwdriver, spintites,

socket or end wrenches. Common nut size are:

½” ….. 5/16-18 hdwe. U-bolts
11/32” ….. 8/32 hdwe Element, insulator assembly
7/16” ….. ¼-20 hdwe – U-bolts

PLEASE NOTE: With the exception of U-bolts, most small nuts and Screws can
be considered “tightened securely” when moderately
screwdriver or spintite. When using tools with Additional leverage, care
taken not to overtighten and Damage components.

vinyl cap to antenna tip.

10. Attach the three 14” capacitance finger sto the 1” x 64 tubing sections, eight inches
above top of coil cap. Orient them at 120° intervals and secure with M-16 clamp.

11. Assembly is complete. Check components and hardware against Assembly pictorial
to make sure they are correctly placed and secure. Antenna may now be mounted via
racket to mast (2” U-bolts supplied) or other suitable structure. See in installation Ideas
on following page.

FEEDLINE INSTALLATION

1. For permanent installations, the feed coax should have lugs soldered to shild and center
conductor. Direct connections of the feedline to the feedpoint studs on the vertical,
properly waterproofed with plastic tape or RTV, etc, will greatly reduce problems from
damp weather.

2. For temporary installations, field days, etc, an SO-239 connector and mounting screws
have been provided. Use of this type of feed connection is recommended for good
weather only. The SO-239 connector, and its male counterpart (PL-259), are not
Designed to resist moisture.

INSTALLATION & OPERATION
FOR 160, 80, & 40 METERS

I. MOUNTING
The antenna may be mounted almost anywhere; round, roof,
tower, etc. remember the support structure should be a 1-1/2”
to 2” steel or heavy gauge alluminium pipe and must be capable
of supportino the antenna in high wind. Light nylon, dacron,
mylar or polypropelene rope may be used to guy the verticali f
required.

II.

Getting a good math performance. KLM’s experience
And recent field studies indicate 1/8 wawe radials are the
best for 160 metres and are entirely satisfactory for 80 and
40 meter performance too. However, if only four are installed,
the mounting racket should also be grounded via a stake or
other suitable source.

If the radials must be installed above round such as
A roof, the at least two ¼ wawe radials are suggested for
Each band in use.

The use of radials is strongly recommended but when they
Cannot be used, it is essential to round the mounting racket
Either through the support post (if its round is good) or a
Round wire.

III.

During the initial tune-up, permanent connections and
Very short leads are just fine and no significant ch’ange should
Occur when the antenna is put into its final working configuration.

GROUNDING

Grounding and round radials are an important part of

TUNING & MATCHING

1.
justed for the preferred frequency of operation. The coil

160 Meters: Once the antenna is mounted, it must be ad-

Provided will allow operation below 1.8 MHZ so some of the
Coil will have to be shorted out. With the coil cover slid
up to expose some of a few turns and make a VSWR measurement.
Continue this procedure until you have found the point of best
match (not necessarily 1:1)

In the event your round system is less than optimum, several
matching techniques can be used.

A) A .002 MFD mica capacitor replacing the 4 – inch pig-

tail lead to the antenna is the easiest to try.

B) Adding a coil from antenna to base round along with

the .002 cap in “A” is another method to try, Use
coil stock similar to the coil in the vertical and
8 – 10 turns should be adeguate.

C) Leave the 4 – inch pigtail feeling the antenna base

And use a .002 or lager cap shunted to round from
Feed point.

D) By using a variable cap in series feed a large

Frequency range can be covered by simply tuning the
Cap for the best match. Use a fixed cap of 1000 pf in
Parallel with a large broadcast type variable.

E) Upward frequency shifts of approximately 25 KHz at

a time are possible by removing one capacity finger
At time for each 25 KHz shift desired. This should
Give little or no effect on SWR or performance.

2. 80 Meter Adjustment: In most installations, approximately
½ of the coil is used for 80 meter operation. If 160
Meter has been set up previously, start your 80 meter tap
Point at ½ of the remaining coil above the 160 meter tap
point. Run a VSWR check across the band every 50 KHz or
100 KHz and find the match point. Move the tap up to in –

crease the match point. Down to lower it. If difficulty is encountered in matching, use the
same techniques as on 160 but limit the capacitance to 1000 pf (.001MFD).

3. 40 Meter Adjustment: The amount of center loading re-

quired for 40 meter is very small since the 160V is al­ready 24 feet long and the ¼ wave is 33 feet full size. As in the 80 meter adjustment,
40 meter tap point will be about ½ of the coil used of 80 or less. Start your 40 Meter
tap point and run a VSWR check across the 40 meter Band. Remember, the 160 V
will be fairly broad due to its nearly full size. As with 160/80, operation, radials are
strongly suggested to permit a good match and performance, but 40 is less critical
than either of the other two bands. If the resonance is set for 7.1 MHz ¾ wave,
operation will be possible on 15 meters at 21.3 without further adjustment. Usually
the match will not require any feed modifications as on the 160/80 set-up unless the
round system is very Poor.

4. Variable Frequency Tuning: Variable frequency tuning on all bands is possible by

setting the resonance low in frequency; 1,750 for 1,800, 3.7 for 3.8, 7.0 for 7.2, and
use “D” arrangement with a large 2000 pf variable capacitor at full mesh. As the
capacitance is lowered toward minimum, the electrical length of the antenna will be
shortened. If all the tap points are insulated and brought out through the bottom cap
and short jumper clip lead is used from the bottom of coil, band change may be
accomplished by merely selecting the desired tap wire with the clip lead. The
variable cap in “D” may be manually or motor driven for fine frequency adjustment.

5. Resonance Frequency Adjustment: When roof/tower mounting the

Resonant frequency may be higher than desired. The frequency May be lowered by
adding the 3/8” O.D. x 24” tubing to the tip of the whip portion of the antenna.
Initially, 18” of 3/8” tube should show. Adjust as required.

IV.

FINAL WEATHERPROOFING

After final tuning and all adjustments have been made on the 160V, it is
recommended that the too end cap over the coil Be sealed where the one inch tube
comes through. This will in No way affect performance, except to extend the useful
lifetime and reduce the maintenance of 160V.

CAUTION!

INSTALLATION OF THIS PRODUCT NEAR POWER LINES IS DANGEROUS. FOR YOUR
SAFETY, FOLLOW THE INSTALLATIN DIRECTIONS.
I. INFORMATION CONCERNING THE RISK OF ELECTROCUTION
Power lines that connect electric service to your house carry more than enough
voltage recuired to kill a person by electrocution. Most often these electric
lines run overhead along property to point on, or near, the
roof of your house. In some cases power lines may also be buried in the ground.
Every year many careless people are killed, or seriously injured, even though
they are aware of the hazard of touching or allowing something they are holding
to touch electric wires. Many of these accidents involve people who are instal
ling (or removing) some type of antenna which is often mounted on a log metal
supporting pipe that has several guy wires and cables attached to it. These
assemblies are cumbersome and, therefore, difficult and unsafe for inexperienced
people to handle even under the best conditions. The slightest wind,rain, too
bright sunlight, too little light, a sloping roof, or other usure footing, and
other characteristics of the installation site along with many other factors can
serve to greatly increase the hazard of possibile contact with power lines.
FOR YOUR SAFTY, GET PROFESSIONAL HELP WITH YOUR ANTENNA INSTALLATION
AND READ AND OBSERVE THE SAFTY PRECAUTIONS OUTLINED BELOW.
II. TYPES OF SUPPORT STRUCTURES
KLM antennas are designed to attach to a mast or pipe not supplied with the
antenna.
The types and sizes are given in most assembly instructions for each model.
SITE SELECTION
A. It is recommended that the following guidelines be used for SAFETY in

selecting a site for the installation.

1. Figure the height of the total antenna assembly including supporting
structures.

2. Select a site for the base of structure that is a distance at
least twice the total height away from the nearest power line.
a site which meets these safety criteria may not be pratical either
because performance of the antenna may be impaired. IF THIS SITUATION
OCCURS, DO NOT ATTEMPT TO INSTALL ANTENNA YOURSELF. GET A
PROFESIONAL INSTALLER TO DO IT FOR YOU

B. There are several different mounting methods used in antenna installations.

Recommendations for best performance appear in some of instructions Covering specific

models of KLM antennas. Common locations include:

1. Roof 3. Side of building 5. Tower or

2. Chimney 4. free standing Mast

The characteristics of your particular site and the type of antenna involved
Must be considered to detemine which is most suitable. Since a detemination
Based on performance may not be compatible with the SAFETY CRITERIA of “A”
above, it is recomended that a professional select the site and make the
antenna installation.

IV. A. If you are not experienced in istalling antennas, you are advised to SEEK
PROFFESSIONAL ASSISTANCE.

B. Select the location to install your antenna with safety in mind. Again
you are urged to obtain proffessional help for a safe installation, as well
as for best performance. More information concerning site selection is
contained in a previous section.

C. Call your electric power company. Advise them of your installation plans.
FOR YOUR SAFETY. Ask them to provide assistance and shut-off power temporarily
during the installation or removal process.

D. Plan your procedure carefully so that anyone helping knows what he is supposed
to do and when. You cannot afford confusion with a cumbersome assembly half Way up or down.
A few tips that may be helpful are:

1. Install your antenna only in good weather and in daylight. Remember,

a small amount of wind or rain or poor visibilità greatly increseas
the possibility of an accident.

2. Assemble your antenna following individual assembly instructions and

attach it to the mast, if used, on the ground near the location planned
for mounting base. Attach the necessary length of coaxial feed cable.

3. If antenna is to be mounted on a mast of one or more sections of

metal tubing or pipe, the assembly should be guyed using three guy wires
per level at about 10-foot intervals starting just below the attachement
point of antenna. Estimate lengths needed and attach one end of
each guy wire to the mast and lay along the mast on the round. When
all are attached, temporarily tie them in a bundle along with the coax
cable near the base of the mast to keep them from flopping about during
erection.

4. A non-conductive rope can be attached near the top of the mast to be held

by a person standing away from those erecting the assembly and used to
guide it away from power lines in the event the assembly starts to fall.

5. Before you raise the antenna, install the mounting racket and, if the

antenna is to be guyed, any anchor bolts at calculated guying points.
E. If the antenna starts to fall and you can’t control it, let go fast. Don’t

hang on trying to recover, let it fall. Remember, should the antenna, mast,
cable (even though insulated for low voltage) or guy wires contact a power
line, the whole assembly will become charged with voltage and anyone touching
it can provide an electrical path to round and be instantly electrocuted.

F. Should the assembly accidently come in contact with power lines,
DON’T TOUCH IT, CALL THE POWER COMPANY IMMEDIATELY.

G. If someone comes in contact with the electric power, DON’T TOUCH
HIM OR YOU ALSO BE ELECTROCUTED. FIRST, remove the victim from
contact with the Electricity. Use a DRY board, stick, or rope. Call for medical
help and Apply artificial respiration if the victim is not breathing.
