Flexible Design:
Unlike Yagi designs, the LP design has more useful lobes to
the sides and back. This gives the antenna a 360 degree omni
ability, with the added benefit of gain in the direction it's
aimed. Why use a unity gain discone or ground plane, when
you can have omni ability and directional gain as well with
the LP.
Tuned to UHF Air
Band: Each antenna is tuned to the UHF Air Band
from 225 to 400 MHz.
Wide Bandwidth:
The nature of the LP design offers a wide bandwidth. Not
only is it wide in the band it was designed to operate in,
but it also does pretty well in nearby bands. This will
help if there's other bands you're interested in.
Solid Construction:
The antenna is constructed of twin 3/4" square aluminum
tube for the booms, and solid 1/4" aluminum round is
used for the elements. The boom is very stiff, as are the
elements. 1/4" stainless bolts and lock nuts are utilized,
not flimsy dimple rivets. The entire antenna is carefully
hand crafted and all aluminum is given a brushed finish.
Weather Resistant:
All fasteners are stainless steel and UV resistant cable
clips are used to hold the coax to the boom.
High Quality N Connector:
Instead of the usual UHF connector that's included with
most antennas, this antenna includes a 50 ohm female N connector.
N connectors are more water resistant and handle high frequencies
better.
Horizontal Mount:
A horizontal mast piece consisting of both UV resistant
plastic and aluminum tube is included with the antenna.
This acts as a stand-off and allows the the antenna to be
positioned away from your mast in free space and vertical
polarization.
Electrically Isolated:
The antenna is electrically isolated from the horizontal
and verticals masts.
Mounting Hardware:
The necessary hardware for attaching the antenna to any
standard 1 1/4" steel mast is also included. Just prepare
your mast and you're all set to go.
Only Partial
Assembly Required: The boom is completely
assembled, along with the feeder cable and mount. The only
things that need to be done yourself are attaching the elements,
and putting up a mast.
AUDIO SAMPLES
Click
for MilTenna LP Audio Test #1: This
is an audio comparison between a standard 1/4 wave whip
tuned to the middle of the UHF mil band on a good metal
ground-plane, and the MilTenna LP. A 1/4 wave vertical is
typically considered to be 'unity gain', as is a typical
discone, so it's a good basic comparison. Note the signal
quality of the tower transmissions first on the 1/4 whip.
Then after you hear the tone, listen to the difference on
the MilTenna LP. The antennas were connected to the same
radio, and next to each other during the test.
Click for MilTenna LP Audio Test #2:
This is a recording of a distant ATIS received on the MilTenna
LP. Compared to the same 1/4 wave whip as above, this signal
was 100% unheard with squelch completely off.
Click for MilTenna LP Audio Test #3:
This is a controller working an aircraft using the same
comparison as file #1. Note first how low the signal strength
is on the 1/4 wave, which had to be recorded with squelch
off to hear anything. Then after the tone, the same controller
on the MilTenna LP.
TESTIMONIALS
"I received the MilTenna LP yesterday.
I was surprised to get it so quickly. I figured something
this custom would take a little while to fabricate and
ship. I was also surprised with the quality. It is very
well made. I work for a MIL spec electronics firm as a
Quality Engineer and Training Instructor (I've been certified
to MIL-STD 2000) and I am unable to make even one suggestion
for an improvement. This antenna is perfect and could
easily be sold to the military! I was able to put it together
in 20 minutes and really didn't need the instructions
although I did glance at them first. Thanks for a great
product,"
Randy S. - Germantown, MD
"Just a quick note to let you know
how happy I am with the MilTenna LP. I live roughly 7 miles
from a military base and a sea range which are my main points
of interest. My Diamond DJ-130 discone antenna (now in the attic)
did a fine job picking up aircraft and ATC on UHF, but the ability
to hear the aircraft transmissions while they were on the ground
was rare occurrence with the discone. No longer a problem using
the LP! I can easily and clearly hear about 95% of the aircraft
transmitting on the ground with greatly improved ATC reception
as well. It adds so much to be able to hear both sides of the
conversations. As far as side and "off-beam" reception
with the LP, I can hear military aircraft on UHF moving through
ARRTC High and Low sectors with the same clarity and strength
as my discone. Did I mention that VHF reception is good too.
I wasn't expecting that! I'm also impressed with the quality
of construction and materials you used in the design. I like
the fact that you chose to mount the antenna close to its center
of gravity. I didn't want a thick mast and/or guy wires cluttering
up my rooftop. The LP is mounted 12 feet above the crown of
my roof with no wires and is balanced and sturdy. I couldn't
have done that with an end-mounted LP design. Thanks for a great
antenna!"
Jay M.- Camarillo, CA
"I have one on my roof, and it has clearly added
areas of coverage that I can't get with my discone. It's very
well made and supported by an active, experienced member of
the mil-scanning community. I put mine at the top of a 2.5'
PVC (Schedule 80) pipe that's attached to a Radio Shack rotator
and a 10' Radio Shack mast with a Radio Shack tripod that's
bolted into a pair of 4' 4x4" "Trex" deck posts
arranged in a T shape to prevent tip over - High gusty winds
haven't moved it, and it's not bolted to the roof. I put this
together in a few hours and have been happy with it ever since."
Jordan H. - NorCal
"Got the MilTenna LP up on Friday. What a really
well constructed antenna. Nothing cheap or cheesy here. Not
much activity here on the weekends, but what little I did
hear, the MilTenna LP beats the grove scanner beam II around
3 db on 372.200. I am very happy with the purchase."
Kenneth W. - Georgetown, KY
"I just received my Miltenna LP. This is a real
nice antenna...Put together very well, very sturdy, also very
lightweight. Performance wise UHF air very good. I can hear
stuff on UHF air that I can't hear with my Diamond Discone
at the same height. VHF mil air (136-145) very good. I am
also picking up my 800 mhz trunk system with full signal bars.
The VHF air (118-136mhz) does take a little hit signal wise
but remember this antenna is tuned mainly for 225-400mhz.
I am about 25 miles north of BWI airport and am able to pick
up UHF and VHF controllers. Even my VHF low (30-50mhz) comes
in pretty darn good. I am using this antenna with a 100' of
LMR 400 with a Male N & BNC male connectors. Overall this
is a very good antenna."
John H. - Timonium, MD
"I received the MilTenna UHF LP today! Wow, that
was fast, thanks! It's assembled, and currently hanging on
the wall inside my office. LOL! I have it hooked up, monitoring
Selfridge Air Base, and the performance is super! And you're
right, it even receives VHF well! It has exceeded my expectations,
and I thank you for a great product."

Tuned to UHF & VHF Air Bands:
The uniquely designed MilTenna Omni is tuned to both the
UHF 225-400 MHz and 118-137 MHz Air Bands. The latest
version now also includes a third set of VHF elements
dedicated to the 138-140 MHz VHF band. Most other VHF/UHF
bands can typically be received as well. This antenna
can be quite esthetically pleasing compared to discones
and other multi element antennas, and it's also more efficient.
The VHF elements can be left off the antenna if desired.
DC Grounded:
A metal ground plane is not needed with this design.
Wide Bandwidth:
The core element of the MilTenna Omni design offers
a wide bandwidth, which is what makes it appropriate
for a band as large as the UHF 225-400 MHz Air Band.
Solid Construction:
The antenna is constructed of 1 1/2" aluminum tube
for the core element and solid 1/4" aluminum round
is used for side elements. No flimsy tubing or dimple
rivets are used. All aluminum is given a brushed finish.
Isolated Mast:
The actual vertical structure is comprised of UV resistant
plastic. This allows the actual elements to be raised
into 'free space', away from your metal mounting mast.
Weather Resistant:
All fasteners are stainless steel and the feed point
is protected by shrink tube.
High Quality N Connector:
Instead of the usual UHF connector that's included
with most antennas, this antenna includes a 50 ohm female
N connector, on the end of a small cable pigtail. N
connectors are more water resistant and handle high
frequencies better.
Includes Mounting Hardware:
Price includes mounting clamps to allow attaching the
antenna to any standard 1 1/4" mounting mast.
Only Partial Assembly
Required: The core antenna is completely
assembled, along with the feeder cable. The only things
that need to be done yourself are attaching the side
elements, and putting up a mast.
TESTIMONIALS
"I purchased the MilTenna Omni UHF/VHF
antenna from DPD Productions last week to serve as my primary
attic mounted antenna for Military air and Civilian air listening.
So far I am very pleased with the range of the antenna, on both
UHF and VHF. I had the original UHF only Mil Antenna from DPDP
and the addition of VHF makes this antenna completely worth
the upgrade. The quality of the construction is top notch, and
while mine is mounted indoors, I would have no hesitation mounting
it outside if I could. I look forward to using this antenna
for a long time."
