Bonito is a company that sells various active dipole and loop antennas for ham radio and DX applications. Recently they decided to test their MegaLoop FX and MegaDipol MDDX antennas on an SDRplay RSPduo, and compare it against a higher end WinRadio. Bonito found that the RSPduo performed well on the weaker longwave stations, but the . DX Engineering Radial Plates. DX Engineering Radial Plates are made of Stainless Steel, 1/8 inch thick and in. x in. outside dime. LZ1AQ Projects. Full information about my projects can be obtained from the following pages: Active Wideband Directional Antenna with Vertically Polarized Small Loop and Small Dipole (New) (January ) A Simple Dipole For 2m Band ; Impact of the Height Above the Ground to the Receiving Performance of a Small Wideband Magnetic Loop. The book Magnetic Loop Antenna with the subtitle Slightly Different Each Time, was firstly published in Czech language in January The writing style of the book is a good example of an effective teamwork between academic theory and practice, where both of the authors examine the subject from their own points of view.

My base station’s loop skywire was tested in its current configuration, feet of wire strung between several trees. The two test antennas were put up in the same configurations that I intended to use them in the field.

DX Engineering RF-PRO-1B Active Magnetic Loop Antennas are designed for low-noise reception of signals within the frequency range of kHz to MHz. Their integral, extra-high dynamic range, low-noise preamplifier is designed for minimum intermodulation distortion in the presence of very high-level signals that would normally overload most /5(5).
Most of the antennas described on this page fit on a lot frontage of only feet, if erected diagonally. Even the meter loop fit within that size, squashed a bit into a rectangle, with the multiband dipole run diagonally between two corners. The dipole was in a high tree at the center in an inverted V form. A) ’s Early receivers used loop antennas, until they were discontinued in favor of long wire antennas, prior to The loop antenna appeared again about This time it was used to eliminate the need for a longwire antenna, and to provide for safer operation of the small midget AC/DC sets that came into wide use at that time. La Loop Antenna è situata sul tetto a due metri di altezza, il paragone è fatto con dipoli rigidi RD40s e DDR5 ed una sloper posti a 3 metri .
