Tarheel antennas are short HF mobile antennas, which use a integrated motor to cover the entire shortwave band (aka screwdriver antennas). The cylindrical, weatherproof lower section contains a large air coil and the solid 12V motor. With the large air coil these antennas have a much higher efficiency than slim antennas of a comparable length, as a drawback these antennas are much more visible...
Located on the lower section are various stainless steel whips, depending on model. Included in the shipment is a 6m long control cable ready to use, the cable is fused and includes a ferrite bead to eliminate interferences into the supplied manual control unit. The antennas have a 3/8" thread on the bottom, the smaller models can be installed directly to any vehicle base with 3/8" connector. The Little Tarheel II could be easily installed for example on the triple magnet base (article 11115).
The included manual control unit can be replaced by an optional automatic control unit. Thus unit stores once found settings and can recall them easily. The required sensor which counts the motor revolutions is integrated into all Tarheel antennas.
The Little Tarheel II has a frequency range 3,5 — 54 MHz, 200 W PEP, max. length 1,37m
The most often requested model, used when larger antennas are just that - too large. The lower section is just 40 cm long and 4 cm wide, the stainless steel whip has a length of 80 cm. This makes this antenna very suitable for smaller cars, without too much negative impact on the overall view.
The manufacturer says that you shouldn't be mislead by the small size of the antenna. In contrast to larger models it can be installed on a higher position on the car, yielding in a much better radiation and less earth losses.
If the antenna is used with the optionally available 1.5m long LT-56 whip, you will see an improvement of approx. 3 dB on 40m and about 5 dB on 80 m. The covered frequency range is approx. 3.4 to 30 MHz with the long whip. Operation on clamps like the MFJ-345T (see photos) is possible.
