74 www.ameritron.com AMERITRON True Legal Limit TM Tuner AMERITRONs ATR-30 True Legal Limit TM roller inductor antenna tuner is ham radios toughest! Itll handle 3KW PEP or 1500 Watts continuous carrier output on all modes and all HF bands into most antennas -- even on 160 Meters where most antenna tuners fail. Its perfect for Ameritrons most powerful amplifiers where the ATR-30 just loafs. All band coverage lets you operate 1.8- 30 MHz including all MARS and WARC bands. Super High Current Roller Inductor Youll see Ameritrons new super high current air core roller inductor. Its edge wound from a thick solid copper strip and silver plated. This produces a large surface area and a massive conductor. It can carry huge circulating RF currents and withstand tremendous heat thatll melt or burn ordinary roller inductors. A gear driven turns counter and crank knob gives you precise inductance control. Two 500 pf Tuning Capacitors Two 500 pf the highest of any antenna tuner variable transmitting capacitors give you no-arc wide range impedance matching for true high power performance. 6:1 vernier reduction drives makes capacitor tuning smooth and easy. Super Balun, 6 position Antenna Switch Super heavy duty three core choke balun lets you match virtually any balanced feedline antenna without core saturation. A 6 position antenna switch lets you select your desired operating antenna. Read true Peak Power Ameritrons active electronic true peak reading meter accurately reads forward and reflected power and SWR simultaneously on a lighted Cross-Needle meter. Roomy Cabinet maintains High-Q Roomy extra-strong .080 inch thick aluminum cabinet gives highest efficiency and lowest loss. 13 1/4Wx5 5/8 Hx17 1/2 D inches.

Great for Ameritrons 1kW AL-80B Amp! AMERITRON's SDA-100 may be the best built, best looking, best performing HF mobile screwdriver antenna in the world! When properly installed on your vehicle this antenna provides coverage from 80 through 10 Meters with a 6 foot whip. Remove the whip for 40 through 6 Meters. What makes our antennas stand above all the rest is that our CNC machined components are from aircraft aluminum or stainless steel and blueprinted, meaning you can take antennas apart and mix them up, then reassemble and they all work the same. Our fiberglass coil form is approximately 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 fingerstock 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 market that we put our outstanding AMER- ITRON warranty behind it. We use a new heavy duty Pittman commercial 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 the sensors already installed so if you decide to add an auto controller now or later, everything is ready. The AMERITRON SDA-100 includes: Up/Down switch; 5 feet of motor DC cable with detachable weather sealed connector; decoupling toroid matching coils. The SDA-100 comes in a handsome black finish, using the Dupont Basecoat/Clearcoat system. Optional accessories: SDM-100, $75. Stainless steel flange mount base bracket , with multiple pre-punched holes. The SDA-100 mounting rod is a 1-in. pipe thread 14-in. long. Ship Code B. SWP-100, $19.95. 6-ft stainless steel whip.
