Group,

I am getting ready to install a 43ft S9 and in considering locations I
have a great location where I can run radials for 80M, but not 160M.  If I
add a 160M coil will I get reasonably good performance on 160M?  Or do I
need to find a spot where I can lay out the 160M radials?

Thanks for your thoughts,

73,
Patrick

If you get a good radials system down with 80 meter you should do great with
it    I have 25 foot radials 25 of them and my chain link fence hook to my
and it work good on 160.

I have work all states and some 10 county with my.

Does the S9 antenna tuen up on 75/80 meters?  If so, how well does it perform? 
I'm thinking of purchasing the 31', but lately, I've been doing more on 75/80
and would hate to buy the 31' if it does not work well on this band.

Thanks and 73!

With out coils the 18 ft and 31 foot will not do 75/80. Only the 43 foot wil do
what you are asking.

It can work as is on 80m BUT very poor as its length is too short!
You can make/buy/get a coil that goes between the 1:1 unun & the vertical to get
the electrical length somewhere near the 1/4 wave and you need at least 4 x 1/4
wave radials out as well.

If your currently working using a horizontal 80/75 aerial, dont forget the
change in polarization in the vertical and the different part of ionpshere you
will be working in (ie working less ground wave )

 
Thanks

I work 80/75 on my 31'.  I have a legal-limit UNUN and it tunes on 80-6m. 
80/75, not the most efficient radiator, but it does make contacts.  I don't use
any coils.

Just like the 43' will make contacts on 160 with an UNUN.

Howdy Folks,
sorry if I'm asking something that has already been asked - I've looked through
the archive and folks talk about  putting at least (4) 1/2 wave ground radials
on their above ground  mounted S9V31... what's the easiest way to do that in mid
air?

I've currently got a twenty-five foot high mast that I'd like to use... the top
of the mast is about level with the top of my roof (about 30' north of the
pole.)  I'm targeting 20M use so, I would need (4) 32.3' radials.    Now the fun
part, how do I put up these radials?

I've seen configurations where folks would run a wire from the base of the
antenna strung through mid air to an insulator then rope from the insulator to a
convenient tie off.  Is that pretty much my only choice?   If I were mainly
interested in 10M I was thinking of attaching stainless steel whips as my ground
radials - I like that as it wouldn't require anything to be strung up... let me
rephrase that - My wife will allow me to do this if I don't have to string
things around the yard/house.  I've got one corner of the house to work with...
as long as it's off the ground and doesn't come out of that corner ;)

Another question for those that made it this far... LDG's information say's NOT
to connect the coax shielding OR the ground radials to an earth ground - Is this
sound advice?  Currently I've got the shielding of my coax tied to earth ground
in the shack and at the antenna feed point... I thought that was the correct way
to ground your setup??

Any and all advice is greatly appreciated!
Thanks,
Alex.

Putting the antenna in the air with tuned radials is known as a
groundplane configuration. People usually say four radials and that
probably is about the optimum balance between performance and
practicality. You could go more than four and you can go less. I'm using
three radials myself and people have gotten by with two or even a single
solitary one.  I use a high pound test rating monofilament fishing line
to hold up the ends of my radials, it's less obtrusive than rope. My
radials themselves are made of 14 gauge insulated copper wire made for
household wiring and they are not really that noticeable up in the air.
The insulation color is green, black would probably be even less
noticeable, I'd stay away from red!
   Don't connect an antenna configured in this fashion to earth ground
anywhere at the antenna end.  I do have all my coax cables shield
connected to a common earth ground at the shack end of things. I can't
imagine not doing that.
Hope this helps and if I can help with any other questions, let me know.

Michael, W4HIJ

Thanks Michael,
One more question about the groundplane configuration and I think I'll be
cleared up.  So, my intention is to focus on 20M but, I plan on 10M as well as
browsing the full 80-6.  So, the 1/2 wave groundplane should be tuned for the
lowest frequency (longest radial) and that will cover the shorter bands equally
well?
Or, do I then need (optimally) (4) more ground plane radials tuned for 10M 1/2
wave - thus having (4) for 20M and (4) for 10M??

Thanks again,
Alex.

From my reading and what I've been taught over the years, its always
been my impression than when you elevate a vertical and string out tuned
radials in a GP configuration that you are going to need radials
specifically cut for each band of operation. Some folks use  the old
flat three or five wire rotor cable for radials and cut the individual
wires to length for the different bands. However, folks on this  list
have told me that if you use an UNUN that things will be as you say and
that if you have only 40 meter radials that the antenna will load up on
bands higher than 40 meters as well. I have no UNUN,  I only use a choke
balun made by winding some of my coax around a piece of four inch PVC
and since I have a small Cushcraft MA-5 beam that does a great job on
20-10 meters, I've had no inclination to even try and load the S-9 up on
those bands. Hopefully someone else can chime in and answer that
question for you a bit better.

I made a ground coil in an "S" type pattern.  I cut it for 20 meters; however i
don't think the length is as important.  I did this as my S9 was about 2 feet
from a fence so I could complete a radial pattern.
I mounted the wire through lengths of wood between a plastic cover as to
"sandwich" the shape in place.  I run this with a Petloany coil and a very
limited radial system in a 180 degree pattern.
I have a photo in the gallery here. As far as performance, I hope to get some
readings done once the snow is gone on my mini VNA analyzer.
My best contact so far has been Belfast, Northern Ireland from Saskatoon Sask
Canada.

I read that if the coil is above ground that it should have a 45 degree angle on
it.  I am not sure if this makes much difference but i did give it a try. My 20m
"s" wind coil is laying on the ground.  I got this idea from an article some one
wrote about a "Note Book" antenna for portable work.
   I am anxious to see how John's third coil is working.  If he claims a lot of
success, I may try this as well, possibly with a roof top vertical mount.  In
the end I have been lead to believe that more is always better! - VE5MJB Mark

Awesome, thanks for all the advice!
I think I"ll give it a try with and with out the shorter radials and see if it
helps... if it doesn't I'll stick with the minimal setup (keep the wife happy.)
As I composed my last post with, "one last question..." you know I doomed it ;)

As for the GP Radials and the angle of drop... in a perfect world that would
be 27 degree drop (below horizontal or 117 degrees from antenna?)
Or is the flat 90 degree horizontal ideal?

Thanks again, I'm so glad I found this forum!
73,
Alex.

Most of us try to angle the radials down some from the antenna although
I don't know what the "ideal" is off the top of my head. I think it
affects the feed point impedance but it's not that critical. All three
of mine are angled down but to varying degrees with one at a much
steeper angle than the other two.  It's based on the layout of my lot
and where I could find a handy tie off place for my fishing line.

Gee, being a little sensitive aren't we John?  I mean, you threw a question out
here called "Pvc lengths" without any context whatsoever about what the question
was related to, what the problem was, or what you were trying to accomplish.  To
be perfectly honest, I didn't know if you were trying to build radials or a new
type of chicken coop.

People on here are generally very friendly and always anxious to help, but
there's no need to go off with hurt feelings when all people are trying to do is
understand your question.

I generally try to make sure I clearly understand the problem before attempting
to offer advice.  But maybe that's just me.

Sorry.  I "assumed"  my bad that the conversation was about the pet
coils is mostly with the 31 foot ones.  I am talking about my 31 foot
S9.  I would like to build one just to try it and see if it works better
than my radial field. I am not a good builder.   I did get the radial
field I was working on down to an acceptable SWR level and with the
tuner it is not a problem.   Like most hams , I like to try things and
since you and many others have a lot of success with the pet coils ,
thought I would try it.  Sorry if I came off like I did.  I will be more
detailed in the future.

I don't think the coils do anything to replace radials.
I understand they increase bands or frequencies.

No problem, just didn't know you were asking about Pet coils.

If you look in the files section, there is a how-to that details how to build
one.  All the dimensions are included.

Oh, and you can build one for any size vertical.  Just so happens that the
instructions I mentioned above are for a 31'.  Should only add to the
performance of your radial field.

Actually they replace radials; no they don't increase bands or frequencies.  A
Pet coil is nothing more than a counterpoise.  Operated my S9 for some time with
no radials at all - only a single Pet coil.  John, K2JHU is running with 3 Pet
coils, no radials.
