Powering active antennas, downconverters or preamplifiers requires very low noise power supplies, as any noise superimposed on the DC power may be able to enter the antenna or the antenna lead, and interfere with the useful signal. Also, electromagnetic interference radiated by the power supply (as would be the case with typical switch-mode universal power supplies) may enter the receiver input and reduce the signal-to-noise ratio of the received signal. |
To provide the cleanest source of DC power possible, WiNRADiO offers a range of power supplies specifically developed for demanding low-noise applications, particularly suitable for active antennas and antenna accessories. These products are available in US (120 V), Japanese (100 V) and European (220-240 V) versions, with regulated 12 V DC output, capable of supplying up to 200 mA. Cords with various types of commonly used plugs are available to suit most countries. |
