This product is discontinued in 2018 and replaced
by the successor MegActiv MA305FT.
MegActiv MA305 Active Antenna
With the MegActiv 305 we expand our choice of USB-powered E-field active antennas. The MegActiv 305 close the gap between the Boni-Whip and the GigActiv GA3005 E-Field Antennas. This noise-free antenna, which is produced according to the highest standards, covers the frequency range between 9 kHz and 300 MHz. 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.
On shortwave, its IP3-value is typically >+30dBm at 7 MHz.
Frequency range: 9KHz – 300MHz
Enlarged and flexible 200mm radiating element.
Flexible power supply
The MegActiv MA305 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
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!"
