The Carolina Windom 80 is parallel and approximately 8 feet away
from the inverted L.
Both antennas have ceramic egg insulators which connect the ends
to Dacron rope.
Radiating elements of both antennas are made of 12 AWG stranded wire with THHN
insulation. The ends of both antennas are clear of any tree branches.
The antenna sloping from the tree on the left to the roof is a
6-Meter 5/8-wavelength dipole.
The inverted L tunes up fairly well on 6-Meters and gets out better
than the sloper!
Antenna placement, facing northeast.
How did you get those wires up there?
That's the question most often heard from neighbors. It takes lots of practice
with a trusty EZ-Hang. It just so happens
that the length of the antennas is such that the ends do not contact any tree branches.
This is very important, in that I do not want any possibility of arcing in wet weather.
This is more of a factor with the Windom (where I run approximately 600 watts max with an
SB-200 amp) than with the inverted L. However, I didn't want any unexpected results.
The feedpoint, using a 1000pF series capacitor encased within a
sealed 35mm film canister.
The "radial farm" - a fence through which the radial runs.The radial
starts at the far right corner, then runs counter-clockwise along
the bottom of the fence to a point in the foreground, just to the right of the
second fence post.
Setup #2 - 14 Radials
All radials are below ground level, with the reason for burying them standing
to the right. The east-bound wires run under the patio stones and to the walls
of the house. All wires buried in the grass are just below the roots.
One of the radials is buried in the flower bed (under the loose bricks)
and runs eastward to the sidewalk.
The sidewalk is along the north side of the garage. The radial runs
along the left side of the sidewalk.
The radial then turns south, runs five feet to the driveway, turns
back east, then down the driveway.
This radial is parallel, more or less, to the horizontal portion of
the inverted L.
One eight-foot radial heads north from the feedpoint.
Radials heading south and southeast from the feedpoint. All wires buried in the grass are just below the roots. The ends of all radials buried in the yard are within 12 inches of the fence,
but do not touch it. Wherever possible, I made sure the ends of the radials were within 0.015 wavelength (15.7 feet) of each other, per ON4UN's Low Band DXing, 3rd Edition.
Two radials heading southeast.
Three radials head southwest.
Two radials heading southwest.
Two radials heading southwest.
Setup #3 - 16 Radials
Buried two more radials (most likely the last two) six months after
the previous 14. Both radials are 1/4 wavelength (128 feet).
Radial #15 was buried from the feedpoint to the
southeast part of the back yard. It then heads eastward along the
south side of the house. Once it clears the southeast part of the
house, it turns and heads northeast.
Radial #16 was buried from the feedpoint eastward,
under the patio and along the north side of the garage.
At the east side of the garage, it heads south between the sections of
concrete, under the expansion strips. Once the radial gets to the
southeast part of the garage, it turns and heads east, along the
south edge of the driveway to the sidewalk. At the sidewalk, it
turns south and runs about six feet until it ends.
Setup #4 - 21 Radials with Six More in the Basement
Buried four more short radials running northeast to northwest, plus
another running eastward, toward the house. Also added a six-radial
grid inside the house, in the basement rafters. This grid was connected
to the eastward radial previously mentioned. The indoor radials only
get connected to the outdoor radial system during the winter, when the
chance of lightning occurring is minimal.
Setup #5 - 24 Radials with Six in the Basement
October 15, 2006
Buried three more short (approx. 30 feet) radials along the west side of
the tree. None of the three are straight. This fills in a gap in the
radials, as well as adds more wire to the system. I connected an MFJ-259B
antenna analyzer to the feedpoint and made the following measurements:
Freq: 1.845 MHz
No telling how much of a difference these additional radials made,
as I had not measured the previous installations.
Setup #6 - 33 Radials with Six in the Basement
November 23, 2010
During the annual autumn cleanup, I noticed that some of my original
electric fence radials were badly corroded and brittle. It was
time to add more radials that could last longer than the
galvanized wire I'd been using for the past eight years.
Earl Cunningham, K6SE (SK) told me back in 2003 that he used 26AWG
enameled copper wire for his radials. So using Earl's suggestion,
I scoured the internet to find enameled copper wire that was at least
26AWG. That lead me to the defacto online auction site, where I
found a dealer that sold various gauges of copper wire with
enameled coating. Five days later, 1000 feet of 19AWG wire was
delivered to my doorstep. The only trouble was, the weather was
starting to get cold and rainly.
With only a few days of free time and good weather left in the season,
I buried nine radials made of the newly acquired wire. I decided
to start my radial replacement starting with the oldest radials - the
ones that ran to the south. With nine of them in place, I decide
that might be a good time to assess the new configuration. Two days
later, I heard ZL8X and worked them on the first call, above a
group of non-hearing stations. If I do not get a chance to install
more radials this season, the present configuration should be okay.
