Benefits, & design
Q) What are the 3 main benefits of a TiltPlate?
A) Number one is safety. No
more climbing a 16 foot ladder to reach any part of your antenna or tower.
Number two is convenience. You can single handedly
lower your antenna from it's normal operating position to ground level for
maintenance in a matter of minutes. Whether you have a simple
aluminum yagi or a high tech antenna like the Steppir, it is nice to work on
them from the ground. Number three is protection in a storm. If you know you will have high winds (e.g. a
hurricane warning), you can lay your tower and antenna down at ground level and
tie it off.
Q) What were the design considerations for the TiltPlates?
A) The design focuses on strength, quality, and durability while
still using light weight materials when appropriate. All of the hardware is
stainless steel to withstand years of
exposure to the elements. The bearings
(click) are rated for the harsh
environment. The TiltPlates use high quality U-bolts from DX
Engineering. The plates are 6061 aluminum and machined on a CNC for
dimensional accuracy. The TiltPlate is designed to protect
your antenna investment and provide convenience and and safety for you.
Q) The TiltPlate is pretty expensive. Why is that?
A) The major costs are for raw material (aluminum plate),
machining, top quality components, and labor. When
you consider a tower and antenna can cost $10,000 or more, the safety
and convenience of a TiltPlate is put into perspective.
Q) Who are the TiltPlate customers?
A)
TiltPlate customers are hams that want a simple system that
lets them work on their antennas on the ground. They like being
self-reliant. Many prefer not to climb towers or tall ladders, so safety
is a factor. They don't want to spend money on cranes or a bucket truck every
time they need to do maintenance. Many of them are capable of
building their own but prefer a tried and tested product.
Q) Can I really lower my tower to the ground for maintenance in just a few
minutes?
A) If you have a crankup / tiltover tower, there is one winch for
each function. You can motorize both winches if desired. And
with the TiltPlate you can really be working on your antenna in a matter of
minutes. Here is a link to my MA-850, you can see more pictures on my "antennas
and towers" web page. Note, U.S. Towers is no longer selling
their raising fixtures with the MD-75 motor but you can still buy the MD-75 and
install it yourself.
Q) What types of antennas can be used with a TiltPlate?
A) The TiltPlate works with any yagi or log periodic type antenna as
long as there is room to attach the boom to the boom plate which is 18 inches
wide. See the section below on "Antenna Applications, Boom sizes, and
Adapters" for details.
Q) What type of tilt over towers can I use?
A) The TiltPlate will work with any tiltover tower that pivots near
ground level or has a pivot point up to about 5 feet off of the ground. If
your tower pivot point is higher than 5 feet it may still work if it can tilt
beyond horizontal.
Installation and
Maintenance
Q) How do I
install the TiltPlate?
A) See the basic
installation
instructions here. There are also additional notes in the "Operation
and Options" section below for some specific antennas. See the FAQ
below on how to make sure the antenna elements are level.
Q) How do I
compensate for the plate offset and insure the antenna will be level?
A) The boom is rotated to compensate for the
offset. Click here to read about several
methods you can use to get the right offset.
Q) Is any regular maintenance required.
A) The bearings have a grease fitting but only require greasing every
5 years or so to keep the moisture out. Any type of automotive
grease is fine. All of the stainless fitting are assembled with
Never-Seize to allow easy disassembly should it ever be required. No other
maintenance is required.
Q) Can you provide installation service or do you recommend anyone?
A) I only sell the product but any professional installer should be
able to do this for you. For example Matt from XXtowers is familiar with
the TiltPlate and has installed them before. His web page is
www.xxtowers.com
Operation and Options
Q) It seems like there should be a latch or lock to keep the antenna from
moving. Why isn't this needed?
A) The weight of the antenna exerts enough force needed to keep the
antenna in place. The tilting plate is intentionally held a few degrees (6-12
depending on boom size) off vertical by the boom u-bolts to generate the down
force.
Q) What happens when the wind really blows?
A) In high winds (40+ mph) the antenna will tilt up and
return to the normal position as the wind subsides. Even that won't happen in most cases
unless the wind is from the right direction (from behind). The wind
actually forces the plates together when it is from the
front side (diagram). This
tilting is normal and working as designed. During
Hurricane Ivan my 4el yagi tilted up about 30 degrees a few times in the 40+ MPH winds.
Gusts of 50+ MPH were recorded in other storms, again with no ill effects.
In very high winds (70+) the antenna can go almost vertical.
Q) I live in a very windy area and would feel better if I could lock the
Tiltplate to avoid the lifting. Is there any provision for that?
A) The KARLock is an optional lock
you can add to your TiltPlate to prevent lifting in heavy wind. The lock
only engages in high wind conditions and only when the tower is in the operational position. You
don't have to climb the tower or remove screws, etc to tilt your
tower. CLICK here for more information.
Q) Is there any problem with the TiltPlate/antenna slipping on the mast.
A) The TiltPlates use 4 U-bolts from DX Engineering to secure the plate to the
mast, they should not slip in even the heaviest wind. If you ever have a
problem you can pin the mast to the aluminum plate but again this is not needed
or recommended. Slipping is not possible with the direct rotor mount
versions.
Q) Is there any problem with the antenna boom slipping where it mounts
to the TiltPlate?.
A) The TiltPlates use 4 U-bolts (or V bolts for the MonstIR) from DX Engineering to secure the boom to the
movable plate. The U-bolts should not slip in even the heaviest wind.
The V-bolts do not grip as well as the U-bolts but when used with the MonsterIR
and EZeye will not slip. If using the V-bolts with other large
antennas, you may want to pin the boom to the aluminum plate.
Q) Since the moveable plate is held out a few degrees, the boom truss mast
is not perfectly vertical, is that a problem?
A) The boom truss attachment point will be a few inches off center ( i.e not
directly above the boom). This is not a mechanical issue and will
work fine. In fact, the offset is required for the "stackable"
TiltPlates to provide the proper clearance for the boom truss cables.
Antenna Applications,
Boom sizes, and Adapters
Q) What types of antennas can be used with a TiltPlate?

Q) What boom sizes are supported?
A) The Tiltplate supports round boom sizes from 1 inch to 3 inches.
Four (4) heavy duty clamps are used in each case.
In addition a number of adapters and modifications are available for other
antennas.
1 to 2 inch boom (e.g.
2 el & 3 el steppir) using V-bolts,
DXE-CAVS-2P - no pinning required due to small size.
2 inch boom ( e.g. DreamBeam 18 & 18E) using U-bolts,
DXE-SAD-200B- no pinning required
2 1/2 inch boom ( e.g. 4el steppir, DreamBeam 36) using U-bolts,
DXE-SAD-250B- no pinning required
2 to 2 3/4 inch boom (e.g. MonstIR) using V-bolts, DXE-CAVS-3P- use EZeye or
optionally pin to boom

Q) I have a Steppir MonstIR.
How do I use the EZeye with my TiltPlate.
A) The
EZeye (click for picture)
can still be used. It is intended to provide additional resistance against
slippage of the boom. The TiltPlate uses 4 V-bolts instead of the 2
u-bolts that are supplied with the Steppir MonstIR Mast plate. So the
EZeye may not required but can be used. After properly adjusting
the boom so the elements are parallel to the ground, drill a hole in the
TiltPlate and install the EZeye bolt. As an alternative, you
can drill and pin the boom with a 3/8 inch bolt.
Q) I have a DreamBeam 18 (or 18e), will the TiltPlate fit?
A) Yes, click for pix
to see how the TiltPlate fits between the tubes.
Q) I have
a 2el Steppir, will the TiltPlate fit?
A) Yes, the TiltPlate is mounted between the tubes instead of in the
factory boom plate position. See the customer pictures for the W2CEA
installation on the main page.
Q) I have
an Optibeam antenna with a square boom, will the TiltPlate work"
A) Yes, there are several adapters available, click for more

Q) Can I order a standard model with the 2 -
2 3/4 inch boom
V-bolt clamps or the 3 inch U-Bolts? I have an antenna that is light enough for the
standard model but has a boom larger than 2 1/2 inches.
A) Yes, all clamping options are available on both models. The fixed sized U-bolts are the preferred choice but either
U-bolts or the V-bolts will work. When using the V-bolts, pinning the
boom to the plate may be required. Please note the 2 -
2 3/4 inch V-bolts only support booms up to 2 3/4 inches due to the
thickness of the plates. These V-bolts are listed on the DX Engineering site as
supporting up to a 3 inch
boom but that is not the case with the TiltPlate.
Q) What about the boom truss mast? (size, material, length)
A) The boom truss mast is optional, check your antenna manual to see if one is
needed. The boom truss clamps are 2 inch U-bolts from DX Engineering. You
can use either a length of aluminum (preferred for lighter weight) or galvanized material for the mast.
The suggested length is up to 4 feet if using aluminum and up to 3 feet if using
heavier galvanized pipe. Check your antenna manual to see where they
recommend attaching the cables. For example, on the Steppir 4el yagi
the attachment point is between 26 and 30 inches above the boom so a 36 inch
mast is more than adequate. DX Engineering is a good source for
tubing.
Mounting Other Antennas above, below and alongside your TiltPlate
Q) Can I put a second antenna
above the TiltPlate
on the boom truss mast?
A) The "boom truss" mast attaches to the movable
plate and can be up to 4 feet long. You can mount a small antenna (e.g. 2M yagi, groundplane) to the mast. An aluminum mast is recommended to keep
the weight down. The total weight of the antenna and mast should not
exceed 15 lbs for the standard model or 30 pounds for the monster model.
Both the weight and antenna height are factors since they counteract the effect
of the main antenna.
A light weight ground plane such as the Diamond X50A
(click for pix) is recommended. It weights about 2.5 pounds and is 5.6
feet tall. The height from the boom to the tip of the ground plane antenna
should not be more than 9 feet. See the customer picture submitted by KB5XE for
an example. See the FAQ below on the STACKABLE Tiltplate, this is
the best option if you want to add a larger antenna
above the TiltPlate.
Q) Can I mount an antenna
along side the
TiltPlate? I have a larger vertical for 2M that is about 17 feet tall?
A) You may be able to mount a taller vertical (for example the
Ringo Ranger AR 10) along side your
TiltPlate using a sidearm. Here is a diagram to
illustrate. You can also use this method to mount a
small 2M yagi above the TiltPlate. See the FAQ below on
stacking Tiltplates, this is the best option if you want to add a
second antenna
above the TiltPlate.
Q) Can I mount another antenna
below the TiltPlate?
A) You can mount a 30M or 40M rotatable
dipole on the mast below the TiltPlate and yagi. The booms should be parallel
so as not to interfere in the tilting action of the TiltPlate
Q) Can I stack two TiltPlates on one mast or
allow the mast to extend above the TiltPlate for a second antenna.
A) The standard TiltPlate is designed to be the last attachment at the top of the mast.
The stackable model allows the
mast to extend above the TiltPlate so you can mount a second TiltPlate,
rotatable dipole, or large vertical above it. Here is a
link to the
STACKABLE TiltPlate for more information.
This is the best option if you want to add a second antenna
above the TiltPlate.
