When properly installed on your vehicle the Model 400A will provide continuous coverage from 1.7 to 28 MHz with the a 6' whip.
The Model 400A like all the Tarheel Antennas is without a doubt the best built, the best looking, best performing, highest power rating motorised antenna for it's size and design on the market.
All of the 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) now or later everything is ready.
What makes these antennas stand above the rest is all of our 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. Our coil form is approximately 2" 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. 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 lbs. of combined contact pressure. With this design you can run up to 250 watts P.E.P trouble free. It's so superior to anything else on the market.
These antennas come with the Pittman 12 volt commercial grade gear motor for the best performance. It is very durable and very quiet while receive tuning.
The weather shield is made of LexanTM. This is the same stuff used on racecar windshields and even used to make bulletproof windows.
The Model 400A comes in a choice of colours (black, white, red or silver) using the Dupont Imron 5000 or Powder Coat Paint System. And folks this is not 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.
That's just some of the effort that goes into a Tarheel Antenna. You won't be disappointed
The antenna is a plug & play system. Included is the antenna. manual switch box, 20 ft. of control cable, ferrite decoupling core, 3/8-24 stud, connectors, fuseholder and fuse.
