Waller Flag Pictures and information
I will be adding to this page over time as I get to the still
photo's and other information about my new antenna.
This antenna was conceived and designed by Doug Waller NX4D hence
the name of the antenna the Waller Flag. Doug
first designed and built his antenna in a vertical position on a
short tower at his QTH in Florida.
This is the NX4D website where you can see Doug's antenna and
learn more about the Waller Flag NX4D Website
Through lots more design work and engineering Doug has now an
agreement with Carlos N4IS to produce these antennas
and sell them commercially. Carlos company name is TOP-BEAM.COM
There you will find more about this antenna. Over the last few
years they have learned that there advantages and disadvantages to
having either a Vertical Waller Flag or a Horizontal Waller Flag
if you have some reasonable height to put it up on a tower.
Carlos has both at his QTH. Another slight variation is the one
that Pete N8PR has where it is an up in the air on a tower but
also has the ability
to rotate the Boom meaning he can change polarization of the
antenna from Horizontal to Vertical or do 45 degrees
either side of Horizontal. In some cases it can be better tilted
one way or the other. Doug has some comments on his
site about Pete's antenna as well as many others in
I chose the Horizontal Waller Flag over the vertical version.
Reasoning was that #1 I had a nice tower height for the antenna.
#2 as long as the antenna is horizontally polarized you don't have
to Neutralize your Towers. See picture of the backyard
mess at K9UWA not pretty to try to neutralize all of the towers. I
may still do that one of these days as I consider the tiltable
version like Pete has.
But at least for today I have a Horizontal Waller Flag.
with only a few days of using the antenna it has already proven to
be better on receive than my directly below it
vertical 4 square transmit array. Here I will ad that after
watching and ground assistance as one of these
Horizontal Waller Flag antennas was put up at Doc N4WW's QTH in
Florida this last spring where Dennis assembled this antenna up
on top of one of Doc's towers I decided there was no way I was
going to try to do that on the top of my tower.
Too many other antennas above and below it to try fighting a 44
foot boom and assembling this antenna up there.
Maybe a couple young guys could do it but unfortunately I don't
have those available so it was
HIRE A CRANE to do the JOB.
Enter the Don R. Fruchey Inc
Crane and equipment company
Yes I have used this company for other Crane / Tower projects
prior to this project.
They have the right equipment to do your job. They also have a
really great bunch of guys in their Crane Crews.
And the above crane is what was chosen for this project. This
crane is capable of 295 foot total height. For this job it was to
be setup to
do 212 feet height. This is due to position of the crane in front
of our house. This kept the crane for the most part on the
driveways rather than taking it into the backyard
where once in the past we managed to get a considerably smaller
crane stuck and had to call out a pair of those big Semi-Wreckers
to get the crane out of the yard.
This puts the crane about 120 feet away from the tall tower. I
also had some maintenance work to do on the other two towers. And
setup as this one was we could reach all three towers
and to the needed work from the same position of the crane. So at
first it was 130 feet out and 150 foot level needed for the work
plus the amount of cable and space
for the "ManCage" so all work was performed from the ManCage on
this the Crane Day at K9UWA QTH.
A Great big Thanks
to the Don Fruchey Crew
So as they say .. ON WITH THE SHOW.
If you haven't already seen it this is the link to the You Tube
Video of the Crane Day Antenna project at K9UWA
then at this point take about 8 minutes and watch the Video or

Dino with the Quad Copter with Camera and his GoPro Headband
camera stuck on my head as I
am the guy up in the "Mancage" doing the work along with one of
the Fruchey Crewmembers.
Dino of course doing all the editing and posting of the YouTube
Video. I wouldn't know where to begin!
I have been asked some questions and did my best to answer them.
However the below pictures will
probably answer some more of the questions.
First someone asked about how the Rotary Rohn 45g mast was built
The whole works sets on top of a Telrex Rotor. It is positioned 7
feet down from the top of the main tower.
The shiney ring you see at the top of the main tower is a 4 inch
wide band of stainless steel rolled into a
near perfect circle. On the legs of the tower are 4 per leg
bearings that run almost against that stainless steel ring.
The tower was put up by me and a crane in 1988
Tower was built by Tower Communications Inc. It was a 225 footer
and the deal was negotiated by my long time old friend
Jack Shutt W9GT who worked at the time for GTE. The tower was down
on the ground in Logansport, IN as it
had been replaced by I think it was a 320 footer by GTE. Jack got
80 feet of the tower and still of course has it up
at his QTH. and I have the other 140 feet of it. Jack obtained
this tower in 1976 and Jack and I put up his 80 feet
in 1977. I put up the 140 foot after purchasing this QTH
from Lamar Ray W9LT in 1988.
Top of the tower with Telrex Rotor
This is a the Tower and antennas as they existed prior to
installing the Horizontal Waller Flag antenna
Ignore the rear two towers. We are talking about the top of the
Top yagi is 2 element Cushcraft 40M
Next antenna down is a 5 element 10M HyGain 105bas It will be
removed and replaced by the new dual purpose
Horizontal Waller Flag plus the 5 element 10M HiGain
elements interlaced on the 44 foot boom.
If you look coming from the top of the tower down and to the right
you see a wire antenna. That is one of 4 identical antennas that
are together the phased 4 square transmit array for 160M. It is
similar to what is known as the K8UR method of building a 4 square
It is switched and controlled by a Comtek 4 square modified box. I
guess since I presently have 312 entities on 160M that it must
The next pictures are of the new Horizontal Waller Flag antenna on
This the assembled horizontal waller flag plus the 5 10M HyGain
elements. Ready to go up!
The boom is 44 feet long. The dual loops are 26 feet across and 14
feet lengthwise to the boom.
Internally what you don't see inside the boom are two matching
transformers to the two loops plus two resistors one for each
In the middle you find an additional match to your 50 ohm coax
transformer and the phasing connections.
This one several of the guys carrying the 75 pound total weight
antenna out to the front yard in preparation to
take it up onto the tower.
Next some pictures of the Crane being setup for the project.
Adding the additional Weights for the crane Total of 66,000 pounds
worth of added weight needed for this job. Plus whatever the crane
I will give you a little hint. First notice the 5 axles on the
crane. They all five Steer when the crane is moving about. The
Crane operator said that each axle is set to maintain 21,000
pounds when this crane is going down the road. x 4 or maybe times
And out in the street yet the Semi with the added 59 foot boom.
Crane is planting the pads to spread the load that is about to be
added to the crane.
Adding the Additional 59 foot boom
Crane up with the ManCage Ready to go
The first trip up was to remove the old 10M yagi. That is the
second one from the top in the above picture. See Video for the
removal of the old antenna.
Next was to bring in the new antenna and up it goes.
Notice the QuadCopter in this picture. See the Video taken by the
Drone on YouTube
Below picture is a nice view of the smallest of the three towers
while we are on the way up with the new antenna.
This tower is a 4hi stack of 5 element HyGain 10M yagi's with an
additional 3 element 20M yagi between the top pair of 10M
The whole works turns with a single rotor from the bottom. The
upper portion is Rohn35 tower. That isn't a typo it is 35 Rohn
slightly better 25G
The fixed tower is the bottom 50 feet of what used to be a Pirod
100 foot tower
The lower antenna is hanging on the cage affair down from the
rotary upper Rohn tower.
Yes that is one very large section of pipe in the middle holding
the whole works together. The top antenna is at 88 feet.
The Rotor is 3 feet above ground level. If I take the chain off
the mast sprocket you can turn that whole stack with one hand by
and twisting the 2 inch at the bottom mast pipe. Yes I designed
and built this one. It was put up in 1990
The Rotor is a 1/3HP 120Vac standard motor driving two tandem worm
gear boxes. From there a chain drive with #100 chain the mast
Direction information is collected by a 500 ohm wire wound pot on
the bottom end of the mast and the control box in the shack is a
HamIV control box. It sends out 24Vac to a 24 volt reversing motor
starter. And of course gets it's direction information from
the 500 ohm pot on the mast. Cogged Rubber belt drive ratio of 1
turn of the mast equal 300 degree turn of the pot.
The rotor for the top of the #2 tower is built the same way. Four
of the five Rotors in these three towers are at waist height from
Only the Telrex on the top of the tallest tower is up in the air.
It had to come down last year for rebuilding the gear boxes. That
one real PITA project. The Rotor was at that point 30 years old.
Guess one can't complain about having to do some rebuild
work on a 30 year old rotor.
Nice View of the crane below us
A really nice view of the countryside from about 170 feet above
the ground level. No I don't think we can really see that much
the Earth at this level. Me and Fruchey are moving in to remove
the old 10M yagi. First part of the project was to get the
feedline off the old 10M yagi as it is
supposed to later be attached to the new 10M yagi.
These guys the Crane op and the man with me in the ManCage are
REAL PRO's. Get us in there without damaging any of the elements
other parts of any of the antennas above or below us. Never any
jerking around always nice and smooth and they can move us ONE
INCH if that is what
they want to do with that Crane and the Excellent Operator. Did
you notice in the one picture the operator had his hand up in
front of his face?
He wasn't saluting us. He was shielding his eyes from the sun due
to the time of day and being a very nice warm sunny day it was.
So he is not only watching he is taking his directions from the
guy in the mancage with me. Amazing pair they are.
Off the the lower left you can see tower #2. After we replaced
this 10M antenna with the new antenna we replaced some 1/2
elements on a 20M yagi at 100' level
and back on the small tower another partial element had come off
of it and was replaced. Original HiGain Element Clamps are Lousy.
They sometimes fall apart
after 20 years or so. Replaced with stainless steel hose clamps
and a drilled hole with a nice big pop-rivet into the joint.
I bet they don't come apart again!
Thanks again to the wonderful people from Fruchey Inc and to many
of my friends who assisted in many ways with this project.
The Horizontal Waller Flag antenna is finally UP and on the tower
and it works very well. More later as we get additional pattern
and see just how well it does work.
73 for now
