A friend of mine is shunt feeding his 80 foot tower on
75 meters. He asked me if he could install another shorter (35 ft)
inductively loaded vertical 1/4 wave away from the tower
and phase them to favor Europe. I was not sure. Will two unequal
physically, but resonate, vertical antennas have the same low angle of
radiation as two that are equal in size? My thought is that they may
have some kind of directivity, but not as low an angle as equal ones.
Yes, there will be a good system of ground radials.

Hi John

Have you considered trying to model the antenna with EZNEC?
Antenna modeling scared me because I'm not bright. But EZNEC is quite
understandable and easy to use.

John, phasing two electrically different driven, shunt fed towers is
not a task for the beginner... It is done by technically experienced
hams (and there are a number on here who can do it in their sleep) and
by broadcast professionals...
However, simply adding a tower 1/8 wave away, loading it to tune~3%
below the operating frequency and having it act as a parasitic
reflector is really quite simple... This is what I recommend you and
your buddy consider... Top hat load the tower and use the inductor
between the top of the tower and the hat as the final adjustment to the
tuning... Use a field strength meter to get the tuning correct...

Perhaps I didn't explain it correctly: What he wants to do is set up 1/4
wave in front of his shunt fed tower that is tuned to resonate say at
3.8MHz, another 1/4 wave vertical on a line toward Europe and feed it
with a 90 degree phasing line. This is not rocket science for two equal
size verticals.

The shunt fed tower is slightly over 100 degrees long physically and the
second vertical is about 45 degrees long physically, inductively loaded
to 90 degrees long.

Will these two unequal in size, but resonated to the same frequency,
verticals behave the same as if they were both the same physical size ?

Short answer, no...
Long answer, yes...

And I cannot do a long answer justice here on a forum such as this...
Perhaps W7EL or W2DU will jump in here and rescue me...
The major issue you face is that the towers are shunt loaded which
creates phase differences between the two right from the git-go, even
when both are resonated... The fact that the feed points of the two
towers are initially out of phase needs to be tuned out in setting up
the 90 degree total phase difference...

Certainly it can be done... You will need to measure the input
impedence and reactance for each tower as built...It will take a
pick-up coil on each tower fed to an oscilloscope so that you can see
the phase difference as you adjust the phasing network / phasing lines
to reach the desired 90 degrees phase lag on the leading element...
Read W7EL's contribution to the ARRL Antenna Handbook on the subject of
properly phasing lines / antennas... This will give you enough
information to decide if you want to proceed...

I long ago decided life is too short for designing all driven arrays
when I can build, install, and tune, parasitic arrays in less time than
it takes me to work the equations for designing the needed phasing
networks for a driven array...

It's easy to see who's read Chapter 8 of the ARRL Antenna Book and who
hasn't! Denny has the right idea.

What you need to do in order to get a decent front/back ratio from the
two elements is to create equal amplitude and correctly phased fields
from them. If one is shorter than the other, it needs to get more
current to produce the same field as the longer one. The current at the
feedpoint of a shunt fed tower isn't equal in either magnitude or phase
to the current in the tower itself. So adjusting the feedpoint currents
for some relative magnitude and phase won't get you the right tower
currents unless you've accounted for the transformation.

It's much easier to get 2 - 3 dB gain than to get good f/b ratio -- you
can goof up the current magnitude and phasing pretty badly and still get
noticeable gain in about the right direction. (In a way it's too bad
this is true, because a lot of people see some gain and assume it means
that they've got the phasing they planned, when in reality they're way
off. Then they extend this misinformation to other arrays and can't
figure out why they don't work.) But with the setup you've described, it
would be easy to be far enough off that you wouldn't get the gain,
either, at least not in the expected direction.

It can be done, but as Denny says, it's much more complicated than just
using a 90 degree "phasing line" as another poster suggested. That
approach generally doesn't work for even the simplest of cases (see the
Antenna Book for the reasons), and it certainly won't work here. What I
would do is model the elements without the shunt feed system and adjust
the base currents in the model (by putting current sources at the bases)
to get the desired pattern. Then I'd make an adjustable feed system like
the L network feed described in the Antenna Book or one of the other
systems described in _Low-Band DXing_. Then I'd arrange some sort of
current probes at the tower bases and adjust the currents to match the
model currents. A final adjustment could be made by putting a signal
source or detector to the rear of the array and adjusting for the best
null. If you do everything just right, you'll get right at 3 dB gain
over a single element and a very good null directly to the rear.

A parasitic array is an option, but again I'd model it. You have the
same problem of getting the right element currents, but now the only
adjustment you can make is the parasitic tower's resonant frequency. You
might have trouble getting enough current in the short tower to do you
much good. A second problem with the parasitic array approach is that
any ground loss will eat you alive. Even what you consider to be a good
ground system might not be adequate, especially for the short element.
Be sure to include a realistic amount of ground system loss in any model
you make.

Alternatively, you can just connect the towers together through some
sort of arbitrary feed system (or you can carefully cut a "phasing line"
-- you have the same probability of success with either method) and have
lots of fun seeing in which directions it seems to work well and which
it doesn't.

At last report, EZNEC won't run under Wine. Wine malfunctions a couple
of places when attempting to run EZNEC, although I think I could
probably work around them. (Of course, there's always the danger that an
update or upgrade would break the program again, since there's no way I
know of to find out which Windows functions Wine emulates correctly and
which it doesn't.) I won't, however, make any attempt to work around the
Wine problems until Wine is able to open the manual, which it is wasn't
able to do at the last report I got. The manual was created with
RoboHelp, a popular help authoring tool, and there isn't any way for me
to work around Wine's inability to read it. If and when anyone reports
that Wine has advanced to where it's able to open the manual (EZW4.hlp),
I'll look again at the possibility of finding workarounds to Wine's
other problems with EZNEC.

EZNEC works fine under at least one Mac emulator, SoftWindows.

I would gladly pay double without a blink, and I doubt that it would be

*Sigh*. I get this a lot.

The main program, 70,000 lines of code at last count, is in Visual Basic
6 and incorporates many direct calls to the Windows API for speed and
increased functionality. The calculating engines (a few tens of
thousands of lines of code) and some main program routines are in
Fortran, and make use of commercial math libraries for fast calculation
of some complex functions. The Fortran routines also make a limited
number of Windows API calls.

The port of a functioning EZNEC program from DOS to Windows, back when
EZNEC was somewhat smaller, took me about two years of full time work.
After some short experiments with VB.NET, it looks like a port to that
(Windows) language probably would take something like six months, plus
an unknown amount of time to find and solve the huge number of subtle
bugs caused by the port. But not only would the user not gain anything,
there would actually be a negative impact, so I don't plan on doing it.
Converting to a C Windows program would probably be a one or two year
project. That might make it easier, although by no means simple, to port
to Linux, but would be of no benefit to Windows users so the Linux
market would have to pay for the effort. Sorry, you'd need to pay a lot
more than twice the current price. (I happily run my EZNEC business for
a fraction of what I can make doing consulting, but I don't work for
nothing. Contrary to what seems like a common perception, I'm not
retired but earn my living from EZNEC and consulting.)

I encourage anyone who thinks it's a simple matter to develop a Linux
program of the level of EZNEC to have at it. It's an untapped market.

And it points out that when people look into buying a computer or
operating system, they should pick what tools (software) they want to
run, and build their system around that. Most people buy a computer or
install an OS, then want vendors to write for that.

I'm coming in a little late on this discussion, has EZNEC been tried on
the Intel based Mac's running windoze?

Very good point indeed. Additionally, for those who do not wish to

Hi Roy,

Non portable design issues inherent in self-serving Microsoft
products. [This is not an aspersion on EZNEC or similar products or
vendors, it is simply the fact of life when you are tightly wed to the
Microsoft platform.]

M$ is a marketing company, not a development company. Ask any vendor
facing Vista, especially those whose Security niche market (Symantec,
McAfee) is being blind-sided.

M$ is claiming to have gotten it (Security) right this time. Of
course, this claim is indistinct from any similar claim made in any
week's press release for the past two decades. Their LATEST release
of (proprietary) Internet Explorer came complete with a feature that
allowed hackers to take over your machine. This news, too, is
indistinct from any industry weekly press release for those same
decades.

The sub-text response to your question is, "Why would Wine try to
emulate everything given this level of jeopardy?" At some point (and
as you basically offered Tom) you simply start over and do it right.
The alternative is that dedicated soul who finds their mission in
bringing down the evil empire by burrowing into every line of reverse
engineered code.

M$ and other industries think they dominate through sheer force of
numbers. One Jon Lech Johansen proved that both Hollywood and Apple
cannot summon up enough engineering head count to withstand being
whipped by a single individual. Of course, both Hollywood and Apple
relied on Marketing to do the Security issues, not their legions of
design engineers (many of whom are equal or better than Johansen).

For those that want to give Linux a try for the first time my advice is
to install it on a separate computer just for Linux. It behaves nice on
a Windows box, but if you are not somewhat familiar with partitioning
and writing to the MBR for a dual boot and getting it back to a Windows
default if you mess up, keep it on another machine.

simply wasn't supported AT ALL! That was special.

Hint: Support for "special" costs. Yeah, cold comfort - sorry.

I'm still hoping to find a flavor of Linux that won't give me indigestion.

Try Rolaids, or pay for support by buying into a vendor with a good
reputation (you already indicate you know several).

Almost every connectivity and configuration issue I researched was
answered through a google newsgroup search, and then going to the
links offered in their discussion. I presume you've already mined
that approach. I have periods of this idle time, like now, that allow
me to research these issues interspersed with intense demand for my
attention. I also make it a habit to keep a journal in a nearly
publish quality format. Memory (wet ram) is for the good things,
ephemeral details like Linux configuration is for filing.

I have nothing to offer for your specific driver need, sorry. However,
for others, feel free to contact me for these guides.

Sorry, I didn't know it was in VB. I can understand how that makes it
nearly impossible as I have worked where we had to do what you did going
from DOS basic to Windows VB. I was hoping it was in something like C.

I know what it's like to have an outsider ask you to port something
that's large and then be surprised when told how long it would take.
Ericsson was a bit miffed at me when told how long to port my US
(Honeywell) version of the MD110 PBX database regenerator to an
international version, and mine was all text based C.

Thanks for the response Roy.
