FIRST...you grab your shovel!!! I chose a (sort of) buried counterpoise that happened to
fit in my backyard. I had to avoid the 2 large garden sheds. I do have some wet ground in
places where run off from the buildings in the area occurs. It seems to work fairly well.
The swr curve on 80 is nice and sharp which seems to indicate a relatively good or
reasonable Q factor. I use this antenna for casual operating and QRP CW work (mainly
during the QRP contests). I have no other low band antenna to compare it to.
I had to avoid the garden area and some areas are fairly rocky and
there are a couple of large garden sheds..so I chose a buried
counterpoise with a few 33 ft radials but most of the copper in the
ground is 1/2 inch water pipe or copper tubing. I ran wires parallel
to the pipes and I laced the pipes together a bit like a copper
spider web of sorts. It works on 160 as well. I can get out and I
operate during the contests mainly giving out points and listening.
I am not a DXer.
The 4 by 4 post gives extra support. It has a small cement pod in the ground.
At the top of the 4 by 4 post..I have a metal support bracket. It holds the vertical in
place and I can lower the antenna to ground quite easily for working on the antenna
or I lower it in real windy conditions as an extra precaution.
YOU can see the main trench carrying the feedline (in a plastic protective hose).
More radials are planned for the future. I can put a few new ones in every year.
RIGHT NOW..April 2011..THE HIGHER BANDS are comming to life with the sunspot
cycle..so I am doing some work on the high bands..and Im thinking of putting up a
"SAWED OFF" smaller modified lightning BOLT QUAD using the rest of the
fiberglass spreaders and a boomless quad spider. SEE pic
This big soldering iron is normally what I use for outdoor antenna work..but for this job..I
used a propane torch and a good hot nozzle to solder the copper tubing copper pipe and
wire all together.
RG 8 feedline with radial wires. The coax is in the irrigation tubing .protects it from
the elements. bought the tubing at a hardware store.
THIS SPRING 2011..I PLAN TO ADD A FEW MORE RADIALS AND A SET OF CONTROL
WIRES FOR A ROTOR WHICH WILL TURN A SPECIAL DESIGNED ROTATING TOP HAT
JUST ABOVE THE TOP COIL. THIS rotating top hat will tune the antenna through the
I bought spools of this wire at ham radio flea markets. Used for ground radials.
Feedline goes up the tower near the shack window. Drainage piping is used for coax
cables that are outside in the elements or buried underground.
The counter poise is buried and some lawn work //and a bit of seeding is
necessary to bring the yard back to its old self. The nice thing about the vertical
is it has a small foot print..no over head wires..and I can take it down easy. I can
try other vertical elements as well and set the HF2v off to the side if I want to try
a different radiating element. I may also try a small transmitting loop with the rotor
above the counterpoise and using the 4 by 4 mast to support the loop.
For a small backyard installation..this is a good antenna system to play around
with and try different things.
This tower 28 ft of tower..is small enough and the mini beam does not raise any
eyebrows with my other city dwelling neighbours. I use ladders to climb the tower in
safety and comfort.
This year..I plan to try a quad antenna for 10 and 6 meters. It will be a sawed off version
of the lightning bolt quad. I have a boomless quad spreader as well.
Boomless quad for 10
and 6 is my next big
The high bands above
20 meters are starting
to perk up.
I will (likely) be
concentrating on 10 and
6 and maybe 12 and 15
and 17 meters in the
next few years.
The sunspot cycle will
likely be going back
down in about 7 years
or so. Then I will likely
do some major
replacement of the HF2v
Starting the process of putting the lawn back to normal. In a few weeks things get
back to normal..or better if you seed and fertilize.
Basically..I put as much copper down as possible or should I say..as much
as I felt I could afford to spend.
I can always did it up and add more later.
Like I did mention previously..however..I am mainly now starting to work
towards having a good signal on 6 and 10 with a quad.
Should be fun when the higher bands open up. The HF2V is just for casual
operating on the low bands..I dont try and bust pileups or anything.
I also use it for short wave listening and listening to the broadcast band
All these interconnecting wires were soldered using a torch.
