MegActiv MA305FT active antenna
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 Dual Power unit CPI 1000DP 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. 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.
- Integrated double surge protection of the active components: Coarse protection by gas discharge tubes with 60V firing voltage with max. pulse leakage current 1kA (8/20µs) with additional integrated ESD fine protection of max. 2kV.
- Standard delivery with DualPower power unit CPI1000DP (external power supply and USB-operation possible)
- IP3:>typ. +30dBm
- IP2:>typ. +50dBm
Integrated double overvoltage protection of the active antenna part
Integrated double surge protection of the active components: Coarse protection by gas discharge tubes with 60V firing voltage with max. pulse leakage current 1kA (8/20µs) with additional integrated ESD fine protection of max. 2kV.
Fernando from Fenu-Radio.ch did the first comparison Test in Mai 2015 and released this test on his Page in German: www.fenu-radio.ch.
Quote from the review by FenuRadio: (translated)
"The NTi MegActiv is a small receiving antenna with excellent reception performance. The construction proved to be unproblematic, similar to the Boni-Whip. From VLF up on the FM band, the MegActiv receives very well despite their small size. When properly setup it provides a nearly unbeatable signal / noise ratio!"
