Ameritron's SDA-100 is without a doubt the best built, best looking, best performing HF Mobile Screwdriver Antenna in the world! When properly installed on your vehicle this antenna will provide continuous coverage from 10 Meters through 80 Meters with a 6 foot whip. Remove the whip to get 6 Meter through 40 Meter coverage.
What makes our antennas stand above all the rest is the top-quality construction. All of our CNC machined components are either aircraft aluminum or stainless steel and blueprinted, meaning you can take 100 antennas apart and mix them up, then reassemble and they all work the same.
Our coil form is approximately 2 inches in diameter and made of fiberglass. The 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 -- it wont wear out, for years of trouble free service!
