MegaDipole MD300DX wideband active dipole<\/h1>\n

The MegaDipole 300DX is a broadband active dipole with a maximum upper working frequency of 300 MHz. The dipole reacts to the electrical component (E-Field) of the electromagnetic field and will deliver best results regarding signal strength and SNR (signal -to-noise-ratio) at locations with little or no locally generated interference. Nonetheless, the receiver to be coupled to this antenna should have a high enough dynamic range so that it can effectively process the received signals.<\/p>\n

In contrast to simple E-field antennas with only one radiating element, the symmetrical construction of the MegaDipole 300DX, will result in almost no negative resonance effects or reflections caused by the coaxial cable.<\/p>\n

First choice for DXer<\/h3>\n

\"\"<\/a><\/p>\n

The MegaDipol MD300DX is the ideal antenna for DXers. Particularly in electrically quiet environments, it can really play to its strength in efficiently amplifying weak signals. In practical operations, a maximum signal-to-noise ratio of 110dB was achieved! (see\u00a0image<\/a>\u00a0)<\/p>\n

Wideband<\/h3>\n

\"\"<\/a><\/p>\n

With prodigious broadband capability and constant receive characteristics the MegaDipol MD300DX is ideal for wideband receivers, SDR\u2019s and WEB-SDR such as KiwiSDR etc. The MegaDipol MD300DX can of course also be operated on all other receivers, including lower-end SDRs and portable world receivers.<\/p>\n

Dual Power Power Supply<\/h3>\n

The MegaDipol is nominally supplied with 10 \u2013 15V DC (max 40mA), however, it can be operated across a wide variety of supply voltages. The antenna can even be operated with slightly reduced IP values at the same gain with only 5 volts via USB. This offers a significant advantage in that you can supply the MegaDipol on trips away from the radio shack or DX expeditions autonomously, using a low-noise USB power-bank.<\/p>\n

The MegaDipol has already attracted a lot of attention with its receive performance at various events such as DX-Camps, field days and in-house exhibitions. In these tests, the MD300DX surpassed the existing antennas usually by 10-15dB in the SNR.<\/p><\/blockquote>\n
