ASSEMBLY HINTS AND TIPS
This antenna uses aluminum tubing and stainless steel fasteners. Although stainless
steel resists rust and corrosion which makes it ideal for antenna use, it is especially
prone to “galling” when being tightened or loosened. When galling occurs a nut can
become seized on the bolt requiring the bolt to be cut or drilled to be removed. Galling
most often occurs once a nut has been torqued at least once. The proper solution to
prevent galling is to coat the thread of the hardware with an “anti-seize” or “anti-galling”
compound designed to prevent galling.
If you are removing a nut that has been installed, especially if it was exposed to the
elements, even if the threads were pre-treated with an anti-seize compound, it can help
to apply a penetrating lubricant during removal of stainless steel nuts to prevent galling.
If during the removal or tightening of a nut, you feel the torque required to turn the nut
increasing rapidly, the best technique is to stop immediately, liberally apply a liquid
penetrating lubricant, work the hardware back in the opposite direction to allow the
penetrating lubricant to fully soak and lubricate the threads. If you force a stainless steel
nut on or off too far once galling begins, the nut will permanently seize.
Aluminum tubing sections telescope together in the element and boom assembly. To
prevent corrosion between the overlapping joints which increases electrical resistance
between sections and can cause the sections to seize together (preventing
disassembly), an anti-seize compound should be applied. Two suggested products are
“Penatrox A” manufactured by Burndy, or “Noalox Anti-Oxidant Compound”
manufactured by Ideal. This will ensure optimal long term electrical and mechanical
performance from your Cycle 24 antenna.
On all hardware, resist the urge to over-tighten (torque) the hardware. Especially
hardware that uses a nylon lock nut - extreme force is not required. Over-torquing will
distort mating surfaces and actually reduce the holding capability and/or strength of the
hardware. Once hardware begins seat firmly, it only takes a few more turns to properly
torque the hardware. Being consistent in applying torque across fasteners is also
important. For instance when applying torque to the two bolts that hold a single clamp on
the boom or to the mast, uneven torque between the bolts can reduce the holding power
of the clamp. When torquing bolts on a clamp, you should alternate between each bolt
applying an even amount to turns to each bolt keeping torque on each bolt as close as
possible. This keeps the clamp engaging squarely and maximizes clamping force. You
can use the exposed threads on bolts the visually gauge if two bolts have about the
same amount of torque.

BOOM ASSEMBLY
TOOLS USED: 5/32” Allen Wrench, 7/16” SOCKET, Tape Measure
The boom consists of three aluminum pieces of tubing with a six foot length of
1.50 inch outer diameter in the center (with reducers pre-installed inside the
ends), and two end pieces that are 1.25 inch outer diameter. Boom pieces are
cut, and holes for the ¼-20 x 2” bolts are drilled at the factory. Identify the 1.5”
and 1.25” pieces of aluminum tubing using the tape measure. These will be the
three largest pieces of tubing that you receive.
Center section - 1.5” X 72”
End sections (2) - 1.25” X 72”*
Secure each end with two ¼-20 x 2.00 inch socket, button head screws and
¼-20 nylon lock nuts. There are two bolts per boom joint.
Attach the two rubber end caps on the end of the boom.
*Overall length of the 1.25” tubing is 72” while the exposed length is 68.5”
per piece.

ELEMENT SORTING
TOOLS USED: Tape Measure
Use a tape measure to determine the outside diameter and the length of each
piece of tubing. Sort the tubing into three piles – .625” (5/8”), .5” (1/2”), and .375”
(3/8”). If you feel comfortable, you can also identify the different pieces of tubing
visually based on its outside diameter and overall length. Your three piles should
have the following pieces:

ES 1- Inventory of Element Tubing – 90 mph version
After you have your aluminum sorted into three piles, you are ready to
assemble the pieces together to make your elements.
The pieces in the table ES1 above that are in bold are the center sections
for their respective bands. These pieces will not telescope into any larger
tubing because they are the largest pieces per band and are the center
pieces.
POP RIVETING
TOOLS USED- POP RIVET GUN, DRILL, 5/32” DRILL BIT, SAFETY GOGGLES.
CAUTION: Follow all safety instructions when using pop rivet tools and other
potentially dangerous tools. Cycle 24 is not responsible for any injuries related to
assembly of this antenna.
This section is meant as a precussor to the next section titled “Assembling the
Elements”. Use the information that you learn from this section while following
the directions in the “Assembling Elements” section.
If you have experience using pop rivets, then skip this section and go to the
Assembling Elements section. If you do not have experience, then we suggest
that you go to Youtube and do a search for pop rivet or how to pop rivet. There
will be several simple examples of how to use a pop rivet gun. Below are step by
step instructions as well:
VDX512
-9-
Revision 3-22-2013
1. Using a hand drill or press, drill a 5/32 inch hole through one side of your
tubing junction. Do not drill through both sides of tubing.
2. Insert pop rivet into hole.
3. Squeeze rivet gun until you hear a POP.
Watch your mark to make sure it does not move while you are drilling your
hole. It is usually best to drill with one hand and hold the smaller diameter
tubing with the other hand.
ASSEMBLING THE ELEMENTS
TOOLS USED- MARKER, TAPE MEASURE, DRILL, 5/32” BIT, POP RIVET GUN
The following is our recommended procedure for marking, drilling, and
assembling elements.
1. Mark all .625” tubing in the center of the tubing at xx inches. This mark will be
used later when centering the element onto the element plate.
2. Mark all .5 inch tubing with a permanent marker at xx inches.
3. Slide one .5 inch tube into one side of .625 inch tube with xx inches exposed.
Drill and secure with pop rivets.
4. Continue this process until you have 5 elements (driven element and reflector)
that have a total of 72 inches of .625 inch tubing in the center with xx inches of .5
inch tubing on either end of your .625 inch tubing. The total length of each of
your 5 pieces of tubing is xx”.
5. Next mark all .375 inch tubing pieces xx from one end.
6. Find the two xx pieces of .375” material and insert one into one end of the .5”
inch piece. Drill and secure. Repeat this step for the other end of the .5” piece.
You should now have an element that is a total length of xx”. Mark this piece
with an R in the center of the element to designate it as the Reflector.
7. Continue step 5 for the remaining elements. When completed, the elements will
be completely assembled.
TAKE YOUR TIME AND MEASURE AS YOU ARE ASSEMBLING THE
ELEMENTS TO CONFIRM THAT THE OVERALL LENGTHS ARE CORRECT.
The diagram on the next page provides the EXPOSED and OVERALL
lengths along with a visual depiction of each elements taper schedule.

Revision 3-22-2013
Note about the picture below.
You might be thinking why does it only show XX inches of .625 inch tubing for the
center section when I have XX inches of .625 inch material. This is because
there is XX inches of .625 inch on each side of the element for a total of XX
inches.

1. Mount the boom on a temporary mast or on saw horses so it is elevated off the
ground.
2. Sort out all the 1.25 inch U-bolt saddle clamps and all of the 1.5 inch U-bolt
saddle clamps. The 1.25” clamp and saddle is the smallest you will receive. The
1.5 inch clamp is the middle sized clamp you will receive.
3. Identify the boom to mast plate (EPM2) and install using 2 1.5 inch U-bolt saddle
clamps (EPM3) with the center of the plate at 81 inches.
4. Install the boom to mast plate at approximately 81 inches. As you install the
element plates in step 4 and 5, ensure that all of the element plates are
perpendicular to the boom to mast plate.
5. Refer to table EPM1 for exact positioning of the element plates. Loosely install
all the saddle clamps on the 4 element plates (EPM4) that will be mounted on the

1.25 inch boom end pieces. Continue this step for the plate that is mounted onto
the 1.5” tubing.
6. Position the reflector element plate with the saddle of the clamp nearest the end
of the boom against the end of the black end cap. Use a level and tighten the
saddle clamps evenly, so they are tight, using a 3/8 drive ratchet and ½ inch
socket (EPM5). Mark this plate as R, designating it as the reflector.
7. Use a tape measure hooked onto the back end of the reflector plate (EPM6) and
position the next plate so the measurement to the back end of that plate is 41”
for the driven element. Tighten that plate using a level so it will be in line with the
first one. Mark as DE designating it as the driven element.
8. Do the same thing for all the plates you have installed using the measurements
listed above and marking each plate for its corresponding element.
EPM 6: Tape measure attached to the rear

Revision 3-22-2013
ANTENNA FINAL CHECK AND TEST – PRIOR TO INSTALLATION
Dimensions:
Refer to figure EPM1 on page 12 and, if there is any question, check the end
dimensions of the elements to ensure they are correct. It is highly unlikely a
mistake could be made except for the installation of the 3/8” tips sections of the
elements.
Hardware Installation:
Verify that all the hardware has been tightened and there are no loose fasteners.
SWR Test
You may connect an analyzer with the antenna only a few feet off the ground to
make sure you do not have a short or extremely high SWR. The antenna will not
have the specified SWR curves unless it is installed at a height of at least 20 feet.
With the antenna at least 6 feet from the ground, you will start to see the SWR
“dip” below 2:1 somewhere in or near the specified frequency range. As long as
you start to see a dip somewhere around (above or below) the frequency range,
you may proceed with installation.
Installation
The antenna should be installed by a professional in a safe manner on a support
structure that is rated to handle the weight and wind load of this antenna, in all
expected weather conditions. The boom to mast plate is supplied with saddle
clamps to mount to a 1.5” or 2.0” outer diameter mast (user supplied). The
antenna is designed to be fed with 50 Ohm coaxial cable such as RG-8 or RG213. Pretest the entire run of coax cable with a 50 Ohm “dummy load” to ensure
there are no problems with either the coax or the coax connectors. Most SWR
issues are due to coax or connector issues and not related to the antenna itself.
Even if the coax was previously being used for another antenna, repositioning of
the cable can cause new connector issues to occur. You should also test the
cable at the full power you intend to run, if possible.
Surrounding metallic objects (other antennas, guy wires, etc.) can affect the
performance of the antenna. If the antenna is not interacting with anything, you
can expect the specified SWR curve, gain and front to rear performance.
