Ground Wire Length?
 

Hi,

I am wondering what limitations are on the length of the ground wire
lead from the transformer/balun to the ground rod? Thanks,

Hi Garth,
As long as you use a nice grd wire like 14, 16, 18 or even 20 it will be
OK.
Be sure that the rod is getting a good grd like a wet spot in your yard
and like 6,8 or 10 ft' long, deeper the better.

Just keep it as short as you can. Here, my ground wires from the matching
transformers are 9' long, into 8' ground rods.

There is no requirement to to ground the BalUn (UnUn) directly. The
antenna lead (coaxial cable outer conductor) must be grounded at the
point where it enters the building. That is where the main ground
should be.

In cases of high ambient noise, such as at my QTH, the following approach
taken from "Broadband Receiving Antenna Matching, Mark Connelly, WA1ION
– 15 July, 2003" has worked for me; at this time I do NOT ground the feedline
coax at any point, instead it is buried in plastic conduit at a depth of
3 feet for a distance of thirty feet (from the shack to the antenna mast),
and the balun's ground wire is only six feet in length (the balun is
in a waterproof box at the feed end of the longwire, which is configured
'Marconi'-style with a short sloped section to the mast insulator.

I use a quadrifilar winding as described he

30.5 m (100 ft.) end-fed horizontal longwire, about 1.5 m off ground
Preferred broadband match = 9:1 transformer
This is the “plain vanilla” antenna used by many DXers. It will work connected straight to a
receiver’s input, but quite a bit more signal can be squeezed out of it if it is matched correctly. In
a narrowband sense, you’d use L-C tuning. For efficient broadband coupling, a 9:1 transformer
does best. In this case we’re talking about an FT114-J with a 7 turn trifilar winding, rather than
the mediocre Mini-Circuits T9-1. Lead 1A goes to the antenna, 1B and 2A are joined, 50-ohm
output is at joined 2B and 3A leads, and common ground goes to 3B. If “station” and “field”
grounds are to be separated for noise reduction, you’ll need a quadrifilar winding with the fourth
winding feeding the coaxial line. There would be no connection at the 2B/3A junction and lead
3B would go to the field-site ground rod system. Opposite side windings (e.g. FT114-J: 21 turns
/ 7 turns or FT140-43: 33 turns / 11 turns) could also work, but sensitivity above 5 MHz may
suffer. A binocular core approach would be a 9-turn antenna winding and a 3-turn winding to
feed the coaxial cable.

You can also carry away EMF by wrapping gnd around your wire NOT on the bare
wire, just close as a bleed.

This is wrong. You do not want the AC power supply return to be your RF
ground. There is a lot noise on the power ground. You want a ground
under the antenna ideally and one that is not used for any other purpose.

Indeed, that is the point I was trying to make in my earlier post.

Who said anything about AC power? I'm assuming we're using batteries;
so what? Code specifies that the lead be grounded where it enters the
building. If you're getting noise from your grounds they aren't very
good grounds.

OK So you have a Noisy AC Mains Ground; and that's all
the Ground you got.

Situation : You are stuck with only using the AC Mains Ground
in your Seventh Story Apartment / Condo : It is 84+ Feet down
to the Earth {Ground} and You Cna't Get There. - Bummer ! ;-{

1 - Use the Cold Water Pipe or AC Mains Ground as your
Radio/Shack's Grounding-Point.
-ps- Try them Both and also try the Outside Looking "Metal"
Window Frames of your Apartment / Condo many times they
are a better Grounding Point then either the Cold Water Pipe
or AC Mains Ground {There is a Reason and a Rational for
that : Anyone know both ?}

=BUT= I Got Noise coming into my Radio / Receiver from
my Grounding Point.- Bummer Again ! ;-{

First try One or more Snap-On Ferrite Beads in your
Ground Wire run from the Grounding-Point to your Radios
and Equipment.

http://www.intermark-usa.com/product...CK_shohin2.jpg

2 - Alternattive to Snap-On Ferrite Beads is a Donut Magnet.
http://www.skycraftsurplus.com/ProductImages/sk1979.jpg
Route the Ground Wire through the Donut Hole several
times and space the Winding out around the outer-edge
of the Donut Magnet; usually 5~6 Wraps will do.

3 - OK -but- I ain't got no Snap-On Ferrite Beads; then a
12" piece of ReBar {Solid Iron Object} with the Ground Wire
wrapped around the ReBar every 1/2"~1" {10~20 Turns}
may help to kill the Noise heard on your Radios coming f
rom the GroundingPoint. - http://en.wikipedia.org/wiki/Rebar

It may do undesirable things, like add directivity.

I was messing around and found that putting my 9:1 transformer at various
lengths along the antenna away from the ground rod, I was able to cancel
out the neighbor's light dimmers, but only on one band at a time. That
meant that it was also nulling any radio stations in that direction,
too.
