Second Hand Tarheel M100A-HP 1 kW Mobile HF Screwdriver Antenna, When properly installed on your vehicle the Model 100A-HP will provide continuous coverage from 3.4 to 30 MHz with the supplied 6' whip. The Model 100A-HP like all the Tarheel Antennas is without a doubt the best built, the best looking, best performing, highest power rating motorized antenna for its size and design on the market. All of the Tarheel antennas come with the sensors already pre-installed so if you decide to add one of the auto controllers (SDC-100 Simple Controller, SDC-102 Programmable Controller, Turbo Tuner, Antenna BOSS, and BOSS II) now or later everything is ready. What makes these antennas stand above the rest is all of the CNC machined components are either aircraft aluminum or stainless steel and blueprinted, meaning you can take 100 antennas apart and mix up the parts then reassemble them and they all work the same. The coil form is approximately 2" in diameter and made of fiberglass. Other antenna builders know fiberglass is better but they choose not to use it because of the expense and difficulty in machining. The 100A HP uses 14 gauge wire for high power capability wound at eight turns an inch for maximum efficiency. The decoupler used is CNC machined for tight tolerances with a custom fingerstick designed to contact 3 turns of coil all the time with over 25 lbs. of combined contact pressure. With this design, you can run up to 1.5 kW P.E.P trouble-free. It's so superior to anything else on the market. The Pittman 12 volt commercial-grade gear motor is very durable and very quiet while receive tuning is also used. The weather shield is made of LexanTM. This is the same stuff used on racecar windshields and even used to make bulletproof windows. The 100A HP comes in black using the Dupont Imron 5000 system. And folks this is not to spray paint in a can. With this, you get a finish that looks as glossy and last as long as the paint on a new vehicle. The antenna is a plug & play system. Included is the antenna, manual switch box, 20 ft. of control cable, ferrite decoupling core, base matching coil, 3/8-24 stud, connectors, fuse holder, and fuse.
