Low power up to 35 watts (cw power).
NOTE:
Do not install the Disguised Decal Antenna System with radios that transmit at more than 75 watts (cw power).
The Disguised Decal Antenna System (“Antenna”) is tuned to the dielectric constant of glass and must be installed
on glass to work properly. The Antenna may be installed temporarily for initial testing by taping (non-metallic tape
only) it to the glass surface prior to removing the paper backing. It is important to note that the VSWR of the
Antenna will be high unless the protective paper backing is removed from the Antenna.
NOTE:
Permanent damage to the Antenna may occur if the Antenna is used without removing the protective paper
backing which protects the adhesive prior to transmitting on your radio. Care should be exercised so that the
Antenna is not damaged by folding or bending.
STEP 1
GLASS PREPARATION
1) Using standard glass cleaner, make sure glass surface is clean where you wish to install the Antenna.
2) Glass temperature must not be under 40 degrees Fahrenheit (5 degrees centigrade) at time of installation.
Preferred mounting locations for the Antenna:
A) For radios transmitting 35 watts (cw power) or less install the Antenna either on the front windshield
3”- 4” to the passenger side of the rear view mirror or on the top centre of the rear window.
B) For radios transmitting between 35 and 75 watts (cw power) install the Antenna on the top centre of
the rear window.
STEP 2
CABLE INSTALLATION
Your low power Antenna may be installed on the front windshield or rear window. If installing on the rear window
with defroster wires see installation on rear windows with Defroster Wires in Section III.
1) After determining the location for the Antenna, route the cable from the desired location to the radio by leaving
enough cable to make a stress free connection to the Antenna.
2) Route the cable along either side of the window trim (as shown in Figure 1 on page 2) and under the door or roof
molding. Cable can be routed either from the left or right side of the Antenna. Any excess cable may be coiled to
accommodate ease of installation after attaching the RF connector (not included).
Note:
Make sure not to damage cable when replacing molding.

STEP 3
ANTENNA POSITIONING
1) When installing on the front windshield position the Antenna 3”- 4” to the passenger’s side of the rear view mirror
at top of the windshield.
NOTE:
Make sure the Antenna is positioned so as to not impair vision while driving.
2) When installing on the rear window (recommended for radios transmitting from 35 to 75 watts cw power) with
defroster wire see section III.
3) Area “B” of the Antenna (as shown in Figure 2 below) is not to be adhered to the window but installed above the
top edge of the window allowing for a flexible connection to the cable. The Antenna and the 3-pin connector on the
supplied cable may be mated either under the window trim or on the trim exterior depending on make of vehicle.
4) After positioning the Antenna per Figure 2, Remove Paper Backing one side at a time firmly pressing outward
from the centre toward the edge thus adhering the Antenna to the desired location. Once installed, the Antenna
may be damaged if removed.
5) Use cable clips to affix cable next to the Antenna.
Make sure the window surface is clean by using standard window glass cleaner prior to permanently installing the
Antenna. Your Antenna, when installed correctly on the front windshield in the glare band, is virtually invisible from
outside of the vehicle. The Antenna is meant to permanently adhere to the glass and may be damaged if removed.
NOTE:
It is possible for the weight of the cable to slowly peel the Antenna off of the window if the cable clips are not used
and the cable is not properly mounted.

Section II
LOW POWER TUNING PROCEDURE
For Radios Transmitting Up To 35 Watts (cw power)
Your Antenna is a new and improved version from Benelec. Due to the variable properties of automobile glass,
your Antenna must be tuned to the specific glass of your vehicle.
NOTE:
Do not install Antenna on metal. This includes “fade to clear/racetrack” and “metal tinting” for defrosting
purposes. If possible check metal content with glass checker to avoid damage to the Antenna and possible
damage to window. For more information see Section III.
1) Trim cable to dimensions per your connector instructions taking care not to nick the inner conductor or the braid.
2) Solder desired connector (not included) per your specific connector installation instructions.
NOTE:
Avoid crimping centre conductor, especially in high power installations.
3) Make sure cable is routed and completely installed.
4) With the non-metal tuning tool (enclosed) and a VSWR meter, match the Antenna to the desired transceiver
operating frequency:
VHF Antennas (135, 146, 155, 165)
Low Power up to 35 watts (cw power)
A) Tune control # 1 (See Figure 3 on page 4) to minimize reflected power and VSWR.
B) Tune control # 2 to further minimize reflected power and VSWR.
C) Repeat steps A and B as necessary.
NOTE:
Make sure tuning assembly screws are not touching metal after installed. Applying electrical tape over the
tuning assembly adjustment screws will eliminate the possibility of shorting the tuning assembly to ground.
UHF Antennas (220, 417, 429, 460, 485)
Low Power up to 35 watts (cw power)
A) Tune control #1 (See Figure 3 on page 4) to minimize reflected power and VSWR.
B) Tune control #2 to further minimize reflected power and VSWR.
C) Tune control #3 to further minimize reflected power and VSWR.
D) Repeat steps A,B and C as necessary.
NOTE:
Make sure tuning assembly screws are not touching metal after installed. Applying electrical tape over the
tuning assembly adjustment screws will eliminate the possibility shorting the tuning assembly to ground.

Section III
INSTALLATION ON REAR WINDOWS
WITH DEFROSTER WIRE
Note:
For radios transmitting under 35 watts, the Antenna may be installed on the front windshield or rear window. For
radios transmitting over 35 watts (35 watts to 75 watts cw power) it is recommended that the Antenna be installed
on the rear window. If possible check metal content with glass checker to avoid damage to the antenna and
possible damage to window.
Place Antenna on top centre position of rear window with area “B” of the Antenna (as shown in
Figure 2 on page 2) above the top edge of the window so that the horizontal lines do not directly
overlap the defroster wires (see Figure 4 below).

Section IV
INSTALLATION WITH TINTING
Many vehicles have some metal content in the window glass. In most cases the performance of
your Antenna will not be affected. However certain types of Installations will be affected by the
various metallic contents found in automobile window glass:
1)
Fade to Clear / Racetrack
On some newer vehicle windshields you may find a metal shield around the edge of the
windshield. To install the Antenna on a windshield with fade to clear / racetrack only area “B” on
the Antenna (as shown in Figure 5 below) should be in the proximity of the fade to clear /
racetrack portion of the windshield.
2)
Insta-Clear
Some vehicle manufacturers offer an optional windshield with the ability to heat the windshield
in winter to eliminate ice and/or fog, sometimes referred to as “Insta-clear” Avoid installing the
Antenna on this type of windshield. If your car has an Insta-clear windshield mount your
Antenna on the rear window.
3)
After-Market Tinting
Some after-marketing tinting contains lead in the tinting to reflect ultraviolet rays. This type of
tinting will affect the Antenna’s performance. To install the antenna with after-market tinting:
A) Select the area desired to install the Antenna.
B) Cut out an outline of the Antenna and remove the tinting.
C) Install the Antenna per Section I.
