- DYMEK DA100D Tuner/Power Supply receiver antenna<br />
> Receives frequencies between 50KHz <strong>and</strong> 30MHz<br />
> Four foot fiberglass whip antenna<br />
> HF pre-amp doubles as the whip antenna mount<br />
> Tuner/power supply supplies 12VDC to the pre-amp <strong>and</strong> acts as a pre-selector,<br />
amplifying only the frequencies desired<br />
- DYMEK DA 100E all wave receiving antenna<br />
> General coverage antenna<br />
> Performance from 0.5 to 30 MHz<br />
> Outdoor pre-amp with 4’8” telescopic element<br />
> 50 foot of RG-58/U coax lead-in <strong>and</strong> control box<br />
> Output impedance is selectable at 50, 100 or 500 ohms<br />
