The DX - 10 Professional is a high quality active antenna for long, medium and shortwave reception. The antenna is designed for indoor as well as outdoor use. The DX - 10 uses a helical as receiving element to reduce fading. Thanks to the very high intercept points, the antenna does not generate intermodulation products. The low noise figure assures that even the weakest signal is received. The DX - 10 Pro can be used both with top-quality receivers such as NRD 545, AOR 7030, Win-Radio GRE as well as mid-priced sets such as the Lowe HF 150, Drake SW 8, Yeasu FRG 100, Grundig ad Sony portables, AOR 3030, AKD HF 3 and similar receivers. The DX 10 is available with a power supply at choice: The Mains/230 adaptor for 210 - 240 V ac, or the Mains /110 adapter for 100 - 120 V ac, or the DC 30 DC adapter for 12 Volts DC power for mobile use or applications where 12 Volts DC is available.
