The Megaloop FX is our latest active loop amplifier from 9kHz to max. 180MHz range. It combines all the outstanding features of the successful MegaLoop ML 200 and ML 052. Thanks to the integrated selectable FM band stop filter and three-stage amplification, maximum flexibility is possible for all types of use.
Flexible application range
This wideband magnetic loop antenna is particularly suitable for locations with difficult reception due to electrical interference (electronic field) in the near field area, it is also made for indoor use or on the balcony / patio. You can place it in the attic, at the window, on the balcony, in the carport attached to the wall or permanently attached to a tree.
Flexible FM band stop filter
Based on the proven MegaLoop platform, an additional low-pass filter and an FM band-stop filter have been integrated which can be activated or deactivated with a jumper. In case of FM interference, the FM bandpass filter can be activated with a jumper and thus FM signals between 88 MHz and 108 MHz will be attenuated by 25 - 40 dB.
Flexible three-stage amplification
The gain of the MegaLoop FX can be adjusted in three stages by an internal jumper (High / Medium / Low)
Frequency response (-3dB) and nominal amplification.
a) FM band stop
1. High gain: 9 kHz - 110 MHz and 25 dB gain
2. Medium gain: 9 kHz - 150 MHz and 20 dB gain
3. Low gain: 9 kHz - 180 MHz and 15 dB gain
b) FM band stop active:
1. High gain: 9 kHz - 52 MHz and 25 db gain
2. Medium gain: 9 kHz - 60 MHz and 20 dB gain
3. Low gain 9 kHz - 66 MHz and 15 dB gain
Flexible ring sizes
MegaLoop FX makes possible the most diverse radiating elements. A PVC-coated and seawater-resistant (V4A) flexible stainless steel wire ring is available as standard. It comes as a 5 m (16.40 ft) circumference ring for indoor, portable and outdoor use. Other lengths, such as 10 m (32.81 ft), are on offer. Lengths up to 20 m (65.62 ft) have also been successfully tested.
In addition, a rigid aluminum ring with a diameter of 40 cm or 80 cm is also available. Thanks to its versatility and gain adjustment, there will always be an ideal combination of circuit size and amplification.
Excellent IP values with power supply from 5 V.
With two signals in the 7 MHz range, an excellent IP3 value of type. +40 dB and an IP 2 value of +85 dBm are obtained with only 5 V (max. 40mA) and therefore the loop can be powered via USB or power bank. A DualPower (bias tee) power supply is included in the standard supply.
MegaLoop can be operated from two different types of power sources. It can be powered via a conventional power supply (round plug 5.5 / 2.1mm) or via USB. Powering via USB has the advantage that no external power supply is needed and that the antenna can operate independently and noise-free with a separate USB PowerBank. The power supply voltage range is 5 - 15 V DC (40 mA max) and therefore the antenna is also suitable for portable use.
Integrated triple protection of active parts
Coarse protection by gas arrester with trigger voltage 60 V and max. impulse discharge current of 1 kA (8 / 20µs) and integrated double integrated protection of max. 2 kV and 8 kV respectively. In addition, the ring connections are grounded with high impedance to avoid static charges.
Tip: with two suction cups you can connect the MegaLoop antenna to a window at home, in a hotel or on the go. Thanks to its flexible ring, transport is really a breeze. In our editorial test "Design of a SDR Part 2" truly portable, I simply put the loop on the tailgate of our Caddy and was able to receive signals wonderfully.
