"Secrets" of a
Successful Stealth Operator by N5IW, Dave
I live in a neighborhood governed by a plethora of antenna
restrictions and other homeowner covenants. Despite these obstacles to
easy radio operations I have been very active in amateur radio. I
work in lots of contests, plenty of DX, and all kinds of QRO and QRP
fun.
FACTS VS. MYTH Many amateur radio operators have the mistaken assumption
that the only way you can ever work DX, Contests, or WAS is with beam
antennas, full-gallon linear amplifiers, and monstor towers. No doubt,
those things do give them the edge and I do not suggest that my antennas
are more efficient or better in any way than a good tower and beam. But; I
have been a successful contester, qrp aficionado, dx hound, etc. All
using simple wire antennas and a vertical. Plus! I get a
particular kind of joy when I beat the big guns in a dx pile
up.
WHY STEALTH? In many cases it is your only way. In others it just
helps keep the peace. Its funny how your neighbors are very
peaceful, even supportive of your ham hobby; and then you put up your
dream tower with that TH-7 super beam. Wow! you work great DX and
get the side benefit of its magnetic properties. Thats Right,
your beam and tower will draw complaints from everyone within
eyesight (and beyond). You will be accused of everything from TVI to
sterility, even though you've been on vacation for two weeks and the power
to the house was shut off. IF THEY CAN'T SEE IT THEY WON'T
COMPLAIN. You'll have to try some of these stealth antennas to
believe this, but it works.
ANALYSE YOUR OPPORTUNITIES
If you live in a neighborhood, town, or
city with the same types of restrictions; look for your
opportunities: -Do you have an attic in your
house, condo, apartment? If you can get in it at all you can use it
to hang all kinds of antennas. I have found ample space for loops
and dipoles in several area ham's homes.
-Do you have any trees? Front or back yard trees
provide opportunities for resonant dipoles and multiband verticles.
The more trees you have the easier it is to hide bigger
antennas. -Read your deed
restrictions and covenants. Very few restrict flag poles or bird
houses. You can hide multiband verticals inside both flag poles and
bird house poles (purple martins birdhouses have to be mounted pretty
high). If you can mount the poles then you can also mount guy wires
to keep your poles up. Inverted vee dipoles and slopers look a lot
like guy wires! -Use your house to
hide a loop antenna under the eaves. Attach directly or with small
standoffs all the way around your house and run feed line in thru a soffit
vent. No way to get a loop here? Then hide dipoles under the eaves on
different sides of the house. Get two dipoles up at 90 degrees apart
and you can work most of the USA with ease. - Do you have a wood backyard fence? A fence can hide
a very low loop, dipole, or doublet. These antennas have a near
vertical take off angle but will work great for stateside contacts of
several hundred miles or more.
Use your imagination! Every
situation has its OPPORTUNITIES. You just have to look for them, and
then ACT. I have seen antennas laid on the grass, metal fences loaded with
a tuner, wire that outlines the shape of the house and painted to
match. All of these are different approaches to a problem but had
the same result. The ham that lived at that location was ON THE AIR,
and making contacts!
TAKE ACTION Build some antennas! Or buy some antennas and get to work
hiding them. I managed to hide a Cushcraft R7000 vertical in some oak
trees on my property for the past 10 years. See my article -Cushcraft R7000 Repairs and
Optimization On my website here>> http://www.qsl.net/n5iw/
APPLY POWER WISELY
Use only what it takes to make the contact.
Sure you can run a linear and beat your way into a pile-up. Do it
while your using your hidden vertical and your neighbor will probaly
scream when you overload his TV, VCR, or stereo front end. I have
the ability to run as much as 700 or 800 watts at this location; but
seldom do I ever run more than 70 watts. In fact, I am a real
fan of QRP so a lot of the time I dont even run 5 watts. At that
power your neighbors will never know you are even on the air. IF you must
crank on your linear, use a resonant horizontal antenna. They
interfere less than verticals with house wiring, tv sets, vcrs, and stereo
systems. Make sure your linear operating correctly, tune it with a
monitor scope for a perfect trapezoid pattern. My guess is you will
have so much fun working stations at 1 watt to 100 watts that you wont
ever need to crank in that extra fire.
