7,5 Volt plug AC Adapter with additional noise filter (power supply)

MegActiv MA305FT Wide Band Active Antenna Wide frequency range 9kHz – 300MHz Small dimensions Dual Power Supply: 5,5V – 15V Selectable FM band stop filter with low pass function Ideal for traveling, at home or DX-Camps IP3:>typ. +30dBm / IP2:>typ. +50dBm Enlarged and flexible 200mm radiating element The new MegActiv MA305FT is an evolution of the popular MegActiv MA305. In addition to small improvements in electronics, the new MegActiv MA305FT has been equipped with a switchable FM band-stop filter. Thus, disturbing radiation from the FM band between 88 and 108 MHz can be easily minimized The new MegActiv MA305FT close the gap between the Boni-Whip and the GigActiv GA3005 E-Field Antennas. This low noise active antenna, which is produced according to the highest standards, covers the frequency range between 9kHz and 300MHz. With a radiating element of only 22 cm / 8,66 inch it can be erected inconspicuously. It can be powered with 5-15 V DC (max.10mA) and alternatively with the supplied Power unit CPI 1500DP via USB. Flexible FM-band stop filter Based on the well proven Megactiv platform, an additional low pass filter and a FM-band stop filter were integrated which can be activated or deactivated with a jumper. In case of FM-interferences, the FM bandstop filter can be activated with a jumper and so FM signals between 88 MHz and 108 MHz will be attenuated by 25 – 40 dB. Flexible power supply The MegActiv MA305FT can be operated by two different kinds of power sources. It can be powered either by a conventional plug power supply (5,5 / 2,1mm round plug) or via USB with a optional Cable. Powering via USB has the advantage that no external power supply is needed and that the antenna can be operated  autonomously and noise-free with a separate USB PowerBank. The supply voltage range is 5 - 15V DC (10mA max) and thus the antenna is also well suited for portable use. You want to test the MegActiv MA305FT live on air?

Boni-Whip Active Antenna 20kHz - 300MHz Wide frequency range 20 kHz - 300 MHz Small dimensions  Ideal for traveling, at home or DX-Camps The BONI-WHIP active antenna replaces the very successful Mini-Whip antenna. Despite its size (only approx. 17 cm long), it renders excellent reception results on longwave, mediumwave and shortwave and additionally for VHF up to 300 MHz. We developed this antenna ourselves and it is built here in Germany, so it really is “Made in Germany” by Bonito. The antenna offers a lot of improvements and better values than the original Mini-Whip. In our newsroom you can see a benchmark test between the Boni-Whip vs. the Mini.Whip: http://newsroom.bonito.net Even on very low frequencies the Boni-Whip produces very good reception results. It can be used beginning with 20 kHz and is a good choice for listeners who are interested in low frequencies. We also thought about radio listeners who are interested in high frequencies and extended the range to 300 MHz. Even with only a little effort you can achieve fantastic reception results; and because of its small size, the antenna can be erected inconspicuously.  The active antenna circuitry is cased in a weather resistant box. The voltage supply is delivered by the antenna cable and the included power supply module.  Boni-Whip: As flexible as you Because of its interchangeable radiating elements (Whips) the Boni-Whip can be used with different elements for experiments. The antenna can thus be adjusted to the surrounding environment or a special reception area. Customer comment I have performed extensive outdoor tests on the Boni-Whip at various locations in Germany, Austria, and USA; and even I am amazed that we have produced an antenna with such small size, mobility and excellent performance/price ratio. You will get a noticeably better antenna for almost the same price as the original Mini-Whip. Boni-Whip: Quality made in Germany The electronics of the Boni-Whip are manufactured in Germany by an ISO9000-certified assembly company in industrial quality and assembled by us in the Bonito QTH. Technical data Boni-Whip Frequency range: 20 kHz -300 MHz Voltage supply: 12V-15V Gain: 3dB Upper Frequency Limit: (-1db): 300 MHz IP3: +32.5 dBm IP2: +55 dBm What's in the Box:  Boni-Whip active Antenna  Junction box  Whip / Radiator 5,5mm/2,1mm barrel DC power connector What else do i need? The Boni-Whip shortwave antenna is delivered without a coaxial cable, as everyone needs a different length. We offer you the right coaxial cables such as the H155 or the even better shielded Hyperflex 5 in different lengths. You need two coax cables: A coax cable between the Boni-Whip and the feeder with BNC plugs. In addition, another coaxial cable, from the feed switch (BNC plug) to your receiver. A stabilized 12V DC transformer power supply (no switching power supply!) Which can deliver approx. 150mA with a 5.5 / 2.1mm barrel connector is required for the power supply. The mast bracket, which is available in 28mm and 40mm, is useful for mounting on the mast etc. The OVP1000 surge arrester can also be useful for current weather events. To protect the BNC connector against weather influences, we offer a self-vulcanizing adhesive tape called NittoTape. If you want a little more amplification, you can also use the longer and flexible radiator, which brings approx 3 dB more level. Please note: The offered coaxial cables are custom-made and cannot be exchanged at a later date!Total length of the cable: cable cut +/- 3% + connector

Where space is at a premium or you live in an area where an antenna is considered an undesirable element in neighborhood, the new GigActiv GA3005 is the ideal solution for the avid listener with a wide band receiver. The low noise GigActiv 3005 Extreme Wideband Active Antenna by NTi covers the whole frequency range from 9 kHz – 3 GHz. The antenna radiator measures only 10 cm (approx 4 inches) and so the unit can be mounted unobtrusively. The antenna requires a supply voltage of  5 –12V DC  (max. 120mA) fed through the coax cable via the standard supplied  DC interface CPI3000DP. It can also be powered via USB with slightly reduced performance. This is perfect for portable use in combination with a PC, which powers the antenna or the antenna can be powered autonomously and noise-free with a separate USB power bank. For shortwave and above 200MHz an IP3 of  typically > +30dBm is achieved. USB-powering possibleLarge supply voltage range of 5-12V. Thus it can be powered by a regular 12 Volt power supply or even via USB. Autonomously and noise- free via a separate USB Power Bank as well.

OMG ?! This antenna will amaze you! 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. 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. First choice for DXer 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 image ) Wideband With prodigious broadband capability and constant receive characteristics the MegaDipol MD300DX is ideal for wideband receivers, SDR's 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. Dual Power Power Supply The MegaDipol is nominally supplied with 10 - 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. "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." You want to test the MegaDipol MD300DX live on air? If you would like to test the MegaDipol MD300DX live, you can now conveniently do this over the Internet with a KIWI SDR.
