MegActiv MA305FT active antenna

Product information "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 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.

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!"

CCMC30 Common Mode Noise Filter

CCMC30 Common Mode Noise Filter Noise filters are nothing new and are often used for transmitting purposes. They are used to prevent unwanted radiation via the coax shielding. It is less known that they can also suppress unwanted radiation when receiving signals, especially when an active antenna is used. However, in this case, the situation is reversed: en route to the antenna, unwanted interferences from electric home appliances can be effectively eliminated. NTi's Coaxial Common Mode Noise Filter (CCMC30) has been especially optimized for maximum common mode noise rejection of >30dB wide band in the frequency range of 150kHz - 30MHz. With slight limitations a much wider frequency range is covered. In the medium wave range for example a noise suppression of up to 45 dB can be achieved. This is possible by using a cascaded system of ferrite cores with various frequency dependent material properties, combined with high quality coaxial cable. For outdoor use, the system is housed in a water-proof enclosure. We recommend to connect the CCMC30 as closely as possible to the receiver.With regard to efficient noise suppression, the CCMC 30 is not very much different from the galvanic isolator GI1000. However, the CCMC30 performes down to lowest frequencies including DC voltage, in contrast to the GI1000, which blocks DC voltages and very low frequencies. The CCMC30 can thus be connected directly to the coax cable which passes the supply voltage or the control signals to the active antenna. A series connection of the GI1000 directly connected to the receiver followed by the CCMC30 right behind the power inserter may result in an even better performance. Technical Data Guaranteed frequency range: 150 kHz – 30 MHz Common Mode Wave suppression: >30 dB: 150 kHz -30MHz (>20 dB: 30kHz-60MHz) Insertion loss: <1 dB (up to max. 150 MHz) Size: 100x68x50mm (132mm with BNC connectors) Connectors: 2x BNC 50Ohms Weight: 320g Made in Germany
