CHAPTER 1
General Description
The Hy-Gain Explorer 14 is a very unique 4-element, three band beam antenna designed for
broadband, high performance, high efficiency
operation on the Amateur 10, 15, and 20 meter
bands. The boom length of 14 feet 11/2 inches
(4.17 m) and a longest element of 31 feet 6 inches
(9.6 m) combine for a modest 17 foot 3 inch
turning radius, small enough for most city lots.
Broadbanding is accomplished through the use of
a monoband reflector on 10 meters, a duoband
reflector on 15 and 20 meters and a very unique
driven element system called the Para-Sleeve
Stainless steel hardware and clamps are used on
all electrical and mechanical connections. HyGain's 50 ohm BN-86 balun and new Beta MultiMatch are supplied. Add-on kits for a 30 or 40
meter driven element are available as option QK-
710. The antenna is designed to fit masts from 2"
to 2 1/2" in diameter and can be rotated with Hy-

Driven Element
The Explorer 14 utilizes a new concept in driven
element design, called the Para-Sleeve System
(Patent No. 4,604,628). Basically, the design consists of on *open-sleeve dipole that has been optimized for maximum bandwidth and directivity
within a Yagi-Uda configuration of parasitic elements. The open-sleeve dipole has evolved from
the coaxial sleeve dipole; however, it is much
easier to tune and exhibits less wind loading. The
ParaSleeve System consist of a trapped driven
element for 15 and 20 meters, electrically
connected to the balun and Beta-Match; and a set
This driven element system allows half element
lengths of 0.209 wavelength on 20 meters, 0.242
wavelengths on 15 meters and 0.241 wavelength on
of two parallel sleeve element for 10 meters.

Preparation For Assembly
FOR OUR OVERSEAS CUSTOMERS: If you
use the Metric System, see American-to-Metric Conversion Table in the rear of this
manual. The United States uses American
units of weights and measures.
Choose a large, clear area to assemble the
EX14. The area must be at least 14' x 32' (4.3
m x 9.7 m). You may wish to use sawhorses or
chairs to support the boom during assembly.
An alternate method involves driving a 5' (1.5
m) leng th of mas t ma te ri al in t o th e gr ound
and attaching the boom and boom-to-mast
bracket to this mast temporarily during
assembly. This permits eye level installation
of parts and allows easy alignment of
elements after assembly. If you assemble this
antenna over a grassy area, precautions
should be taken so that hardware is not
accidentally lost during assembly. A concrete
The assembly of this antenna will be easier if
you read this manual completely through at
least three (3) times before beginning
assembly. Allow at least 5 hours for assembly.

Option QK-710
The Hy-Gain Model QK-710 is an optional kit
that will allow you to add 30 or 40 meter
operation to your Explorer 14 antenna. The
kit supplies all the necessary hardware and
instructions to add an extension onto the
Para-Sleeve driven element for either 30 or 40
If you anticipate adding this kit to your
Explorer 14, you may make the following
adjustments before adding the QK 710.

Select the boom-to-bracket clamp parts (Item
Nos. 2 and 3). Loosely assemble them on the
boom ends (Item No. 20), as shown in Figure 2.
Line up the holes on both brackets and both
boom ends. Secure the two brackets together
with four (4) 1/4"-20 x 3/4" bolts, lockwashers
and nuts. Secure the brackets to the boom ends
using the 5/16"-18 x 2 3/4" bolts, lockwashers
and nuts. Tighten these six (6) bolts securely.
Assemble the two cast aluminum brackets (Items
No. 1) on the mast at the desired height above
your tower. Secure the two brackets together
using the two (2) 5/16"-18 x 3" bolts,
lockwashers and nuts. You may wish to drill a
hole through your mast so that a 5/16"-18 x 3
1/2" bolt may be inserted through the cast
brackets and the mast and tightened. This bolt
will prevent the antenna from twisting on the
mast in high winds. See Figure 2. The four (4) 5inch bolts will be installed when the antenna is
installed on the mast.

y
Because of the broadband nature of the EX 14, it is supplied with only one setting for use
on all modes on all of the 20, 15, and 10 meter
bands. If assembled and installed correctly,
the VSWR should be below 2:1 on any
frequency on these bands.
The following steps will be in singular form.
Do each element assembly step, first for one
side of the boom and then for the other side.
The dimensions shown in Figure 12 are in
American units on the right side and Metric on
the left side.
The elements may be assembled indoors, perhaps in the garage or basement work area,
especially if the weather is cold, wet or windy
outside. Take your time, and recheck all
element dimensions. The elements should be
attached to the boom outside, at a location
near your tower.
After each element is assembled to the boom,
tighten the eight (8) 1/4"-20 x 3/4" bolts. After
all elements are assembled, make sure that
they all lie in a horizontal plane at 90 degrees
to the mast, then securely tighten the two (2)
anchor bolts on each element.

Attaching the Antenna to the Mast
IMPORTANT
The Explorer 14 is a moderately large antenna
and requires some consideration as to how you
are going to get it to the top of the tower.
Thoroughly read this section before beginning to
install yo ur an te nna.
Installation on a Crank-Up Tower
Crank the tower down completely or as low as
it will go, and block all sections from moving
by using a 2" x 4" piece of wood or a solid
iron bar for heavier towers. The block should
be inserted through the lattice structure
before the tower is completely down, then the
tower can be cranked down until the block
takes the weight off the winch.
Use a ladder to reach the top of the tower.
NEVER CLIMB THE LATTICE
STRUCTURE OF ANY CRANK-UP
TOWER! Attach the mast to the tower and
rotator. (The cast aluminum boom-to-mast
brackets should be installed on the mast as
shown in Figure 2. See Chapter 2.) Attach a
gin pole to the tower to assist in lifting the
Explorer 14.
Attach the lifting rope to the balance point of
the antenna. Be careful not to damage the
rear sleeve assembly next to the boom-to-mast
clamp. The lifting rope should be fed through
the gin pole or other pulley arrangement attached to the tower. The other end should be
at ground level, available to the ground crew
for lifting. Guide ropes may be loosely looped
over the boom ends and used by the ground
crew to guide the antenna away from the
tower and ladder. Each guide rope's two loose
ends should be held by the ground crew, so
that the guide rope can be retrieved. Always
use a nonconductive type of rope if working
near power lines.
When the antenna reaches the mast bracket,
the four (4) 5" bolts should be inserted
through the holes in the mast brackets and
secured using 5/16"-18 lockwashers and nuts.
Tighten all bolts securely. You may wish to
use a deep well socket set to tighten these
bolts.
Other Types Of Towers
When installing the Explorer 14 on a guyed
tower, you may wish to use a different guide
system. If you have insulators on your guy
wires, y ou will need to keep th e antenna away
from the guy wires as well as the tower. You
may wish to use two ropes attached together
at the top of the tower and attached to the
gound about 15 feet apart. These two ropes
can then be used to slide the antenna on as it
is also being lefted. The two ropes will need to
be far enough from the tower base to allow
some sag and still support the antenna away
from the guy wires.
WARNING
Installation of this product near power
lies is dangerous. For your safety, follow
the instructions.
Lightning Protection
For proper lightning protection, you must
ground your antenna supporting structure.
Grounding will ensure noise-free operation
and low SWR. A proper ground consists of a
1/2" x 8" co pper clad steel groun d rod d riven
into the ground approximately 12" away from
the concrete tower base. Connect the tower to
the ground rod using #8 copper wire and
commercial noncorrosive
round clamps.
Attachment of Feedline
,
Use a good quality 50 ohm coaxial
transmission line such as Times Wire and
Cable RG-213/u or Belden 8214 (foam) or
Belden 8237, 8267 or 9251 (solid). Take extra
care when soldering connectors to foam
dielectric coaxial cable. Weatherproof all
connectors which will be exposed to rain or
ice, with Coax-Seal® or another similar
substance. There is no need to make the
feedline any multiple of wavelengths long.
Attach the transmission line to the BN-86
balun and tighten the connector securely. Tape
the coax to the boom and mast to ensure good
strain relief.
These VSWR curves are typical for this
antenna mounted 70 feet above the ground,
horizontally polarized. Similar curves can be
expected for this antenna mounted between 30
and 100 feet above the ground. DO NOT TRY
TO TUNE THIS ANTENNA FOR LOW
VSWR AT GROUND LEVEL. Higher VSWR
can be expected if mounted at less than 30 feet
or above a roof or large metallic structure.
Forty (40) and eighty (80) meter wire dipoles
should be kept at least 6 feet below this
antenna.
Guy wires should be broken up into
nonresonant lengths (less than 12 foot lengths)
and insulated from the tower if mounted
within 10 feet of the top of the tower.

Operatio
CHAPTER 4
Connect the other end of your transmission line
to a good quality SWR meter or Thruline@
wattmeter and then to your radio. While using
lower power (less than 200 watts output), check
the VSWR across each band from 14.0 to 29.7
MHz. Record this information for future
reference. See Attachment 1 on the last page of
this manual. Check the VSWR periodically to
ensure proper operation.
The front-to-back ratio may be checked by using
a steady carrier transmitted by a local station (at
least a half mile away). The front-to-back ratio
may be affected by the proximity of metallic
structures or guy wires less than 10 feet below
the antenna.
This completes your installation of the Explorer
14. Happy DX'ing!
Maintenanc
The Explorer 14 antenna is designed to be
relatively maintenance free. All hardware, except
for seven (7) long bolts used in the boom-to-mast
bracket, are made of passivated stainless steel.
The seven (7) long bolts are plated with a thick
layer of cadmium with a protective coating of
clear chromate. The internal tooth-type
lockwashers used in this antenna are made of a
slightly magnetic grade of stainless steel. The
element tubing clamps are made of all stainless
steel. All other metallic parts are aluminum. All
insulators are made of either black polyethylene
or black Cycolac®.
Hy-Gain now recommends genuine Penetrox-A©
from Burndy Corporation for use as an antielectrolytic compound within element
assemblies. This prevents aluminum oxide from
forming on the aluminum surface, thereby
maintaining high electrical conductivity between
element sections, especially in coastal
environments. No other type of conductive paste
should be used. Penetrox-A© may be obtained
from any electrical supply store.
A light amount of clear lacquer or an acrylic
spray may be used to coat the exterior surface of
the element assemblies if heavy oxidation is
likely to occur. Do not use any coating on trap
assemblies. Heavy oxidation of aluminum may
occur if the antenna is installed within 5 miles of
salt water.
When storing this antenna (or if awaiting
installation), care should be taken not to damage
any trap assembly or allow any dirt or insects to
enter any trap assembly. Do not leave the
elements in a grassy area, as wet grass will stain
the aluminum.
Optional
If you use a 1500 watt continuous duty power
amplifier or if you use RTTY at 1500 watts on
this antenna, the BN-86 balun should be replaced
with a suitable high power balun or RF choke.
Hy-Gain makes a new high-power current-type
balun rated at 2000 watts continuous, Model
/BN-4000B for beams.

Troubleshootin
If you encounter problems with the operation
of your Explorer 14, follow these steps to
isolate the cause.
Usually you can isolate problems that occure
in either
our antenna or feedline/feedpoint.
If you experience high VSWR on all bands,
your problem is probably in the feedline or
balun. If you experience high VSWR on some
bands but not all bands, look for problems in
the antenna element lengths or traps or nearby
resonant structures.
