The RF Systems DX-One Professional MkII is an omni directional active vertical receiving antenna covering 20 kHz to 60 MHz (10 kHz to 90 MHz with reduced specs). The multi-polarized DX-One Pro MkII addresses the issue of polarization fading found so often on shortwave. Another outstanding feature of the DX-One Pro is its excellent resistance to intermodulation problems. The rear panel has two isolated SO-239 outputs for two receivers. The user must supply coax between the antenna and the control box (PL-259 to PL-259). The control box unit features a step attenuator (+6 dB to -40 dB). It also has a switchable medium wave suppression feature which suppress signals from 540-1640 kHz by up to 40 dB.

This antenna has a very high 2nd order intercept point of no less than -80 dBm and a 3rd order intercept point of +52 dBm or better. The gain is +10 dB (± 2 dB) over the entire range 20 kHz to 60 MHz (ref dipole).

The DX-One Pro MkII is 47 inches (1.2 meters) high and the diameter is 39 inches (1 meter). All mounting hardware is stainless steel. Operates from 110-130 VAC 50-60 Hz 8 VA. The required PL259 to PL259 coaxial cable to connect the control box to the antenna is not supplied. Six month limited manufacturer's warranty. Click here to view rear panel.
