AMERITRON . . . the World’s High Power Leader! 97
AMERITRON's SDA-100 is the best
built, best looking, best performing HF
mobile screwdriver antenna in the world!
Properly installed on your vehicle this
antenna covers 80-10 Meters with a 6 foot
whip. Remove the whip for 40-6 Meters.
What makes our antennas stand above
all the rest is that our CNC machined com-
ponents are from aircraft aluminum or stain-
less steel and blueprinted, meaning you can
take the antennas apart and mix them up,
then reassemble and they work the same.
Our fiberglass coil form is approxi-
mately 2 inches in diameter. Other antenna
builders know fiberglass is better but they
choose not to use it because of the expense
and difficulty in machining. We use 14
gauge wire for high power capability,
wound at eight turns an inch for maximum
efficiency. We machine groove our coils so
they will not loosen up or jam -- they won't
wear out, for years of trouble free service!
New Lexan cover is super durable and
protects your Ameritron screwdriver for
years of trouble-free service.
The decoupler we use is CNC machined
for tight tolerances with custom finger-
stock designed to contact 3 turns of coil all
the time with over 25 pounds of combined
contact pressure. With this design you can
run up to 1.2 kilowatts PEP, trouble free.
It's so superior to anything else on the mar-
ket that we put our outstanding AMER-
ITRON warranty behind it.
We use a new heavy duty Pittman com-
mercial 12 volt gear motor, which is very
durable and quiet while receive tuning.
This motor is super heavy duty for years of
trouble-free service. Antennas come with
sensors already installed so if you add an
auto controller, everything is ready.
The AMERITRON SDA-100 includes:
Up/Down switch; 5 feet of motor DC
cable with detachable weather sealed con-
nector; decoupling toroid matching coils.
SDA-100 comes in a handsome black,
using Dupont Basecoat/Clearcoat system.

save 10 screwdriver antenna
positions in memory.
With a push of a button,
you can quickly return to
any saved position.
