2.0 FUNCTIONAL DESCRIPTION

2.1 General

The V147-CL2 is intended to be used as part of an overall communication system which
consists of a transmitter (or receiver or transceiver), an antenna coupler and the antenna.
It is used around the world in many applications with requirements in the 100 kHz to
5000 kHz bands for marine and aeronautical radio beacon and, with Top-Hat radials, as a
Traveler Information Service (TIS) communication systems.

2.2 Electrical Description

The Valcom, Model V147-CL2 is a field proven, coil loaded, 49-foot antenna. The
second section is inductively loaded to a resonant frequency slightly higher than the
operating frequency specified by the customer.

2.3 Mechanical Description

Third Section. This is a hollow tapered cylinder made of circumferentially and

longitudinally wound fibreglass filaments using a thermosetting epoxy resin matrix.
Embedded in the composite are multiple beryllium copper strips laid in a single-turn
spiral and secured at the top end to a threaded female ferrule into which the Valcosphere
is secured. Depending on the options chosen, there may be up to eight whiskers that
thread into the Valcosphere ferrule to form the Top-Hat structure. The surface of the
section is smoothed, primed and painted with a polyamide epoxy surface coating.

V147-CL2

Coil Loaded Section (Second Section) The coil loaded section is constructed in the

same manner as the Third section. The coil is wound using enamel copper wire and is
also embedded in the fiberglass. The ends of the coil are braised to the respective
ferrules.

Bottom Section. The construction and finish are the same as for the other sections
except that the diameter expands out to meet the mounting base. The ferrule is threaded
to fit into the bottom of the Coil Loaded section. Multiple parallel conductors are
connected to the ferrule at the top and to a conducting ring near the bottom. The feed
terminal extends from the bottom ring to the surface of the antenna approximately 18.0
inches from the bottom of the base flange. The base can withstand a flash-over voltage of
25 kV.

NOTE: The sections of the antenna cannot be interchanged with other antennas

due to the unique locations of the locking screw holes.

VTM-04-006A

3.1 Scheduled Maintenance

The antenna is virtually maintenance free. The external finish is an epoxy polyamide two
part compound paint. The minimum finish life before showing signs of deterioration
should be at least six years under normal climate condition.

When used in salt-water environments, it is recommended to wash the antenna base with
fresh water to remove any build-up of dried salt residue. This should be performed on a
monthly basis or after pr olo nged exposure to sea-spray.

Use a small wire brush to clear any debris from the drain groove found in the bottom of
the antenna base.

3.2 Corrective Maintenance

Generally, no corrective maintenance is possible or required. If one section is severely
damaged, it must be replaced by a new section. Workshops having experience in
handling epoxy fibreglass composite structures may attempt the repair of minor surface
damage if practicable.

3.0 MAINTENANCE

NOTE

DO NOT USE LEAD BASE PAINT TO TOUCH-UP OR
REPAINT THE ANTENNA. USE ONLY EPOXY BASE PAINT.

4.1 Unpacking

Open the shipping crates and remove the antenna sections. Remove all packing material
including the male ferrule protectors on the antenna sections. The V147-CL2 antenna as
shipped consists of the items listed in Table 5.1. Check that all of the items are present
and in good condition.

4.2 New Site Preparation

(1) Check to see that the underside of the steel base plate at the site is free of cables

and other obstructions.

(2) Excavate and pour a concrete pad to where the antenna is to be installed

(recommended foundation details can be found at the end of this manual).

(3) Install Ground Screen (recommended ground screen can be found at the end of

this manual).

4.0 INSTALLATION

4.3 Assembly and Installation of Antenna on the site

The following steps should be followed to assemble the V147-CL2 antenna (see Figure

4.1).

(1) Remove retainer pin on the hinge plate and open top plate to 90<, mount the

bottom plate of the hinge plate on the anchor bolts. Secure with hardware (flat
washer, lockwasher, and nut) on each bolt.

(2) Obtain four to six saw horses or other supports that will hold the complete

antenna horizontally at a convenient working height and place them in the
assembly area. The assembly area must be a cleared working space approximately
55 feet long and 20 feet wide.

(3) Support the base section (item 1, Table 5.1) on two of the saw horses.

(4) Align mounting holes in the plate with holes of the antenna flange and gin pole

adapter, secure base section to the plate with hardware, fed through from
underside.

(5) Tie a rope (1/2" diameter polypropylene) to the eye of the gin pole, then slide the

5

VTM-04-006A

V147-CL2

gin pole into the pipe attachment and secure.

(6) Support the second section (item 2, Table 5.1) on two other saw horses so that the

two sections lie in the same straight line.

(7) Make sure the threads of the male ferrule on the base section are clear of foreign

material and free of burrs.

(8) Assemble the second antenna section onto the base section and tighten to align the

arrows at the joint using the strap wrench supplied (item 6, Table 5.1). Install the
setscrews and seal with the sealant provided (items 7 and 8, Table 5.1).

(9) Assemble the third section (item 3, Table 5.1) to the second section by repeating

steps 6 to 8.

(10) After all sections are assembled, assemble the Valcosphere (item 4, Table 5.1) to

the top of the third section. Install the setscrews provided (item 8, Table 5.1).

(11) If the antenna was ordered with a Top-Hat, install and tighten the 8 Whiskers

(item 5, Table 5.1) into the threaded holes found below the Valcosphere.

(12) The antenna now is ready to raise to its final position.

(13) Tie the rope (from gin pole eye) to a point about halfway up the second section

(see Figure 4.1). A timber hitch knot is recommended.

(14) Erect antenna by applying a gradual and constant pull on the rope referred to as

the “Pulling Force” (a winch or vehicle is recommended).

(15) Once the antenna is in the vertical position, insert retainer pin back into hinge

plate, secure with tension pin. Use bolts (supplied) to secure upper and lower
plates of the hinge plate together.

(16) Remove the gin pole. Electrical connections can now be made.

4.4 Electrical Installation

Very carefully secure the lead from the transmitter, transceiver or coupler to the antenna
feedpoint. Depending on the options chosen during purchase, the feedpoint may be an
acorn screw and lock-washer located approximately 18 inches up from the base or it may
be a threaded post out the bottom of the antenna.
