The Mega Loop FX is our latest active loop antennar for the 9kHz to max. 180MHz range. It combines all the outstanding features of the successful MegaLoop ML 200 and ML 052. Due to its integrated selectable FM band filter and the three-step amplification a maximum of flexibility for all kinds of use is possible. Flexible range of application. This broadband magnetic loop antenna is especially suitable for places with difficult reception due to electrical interferences (E-field) in the near-field area, it is also made for indoor use or on the balcony/patio. You can put it up in the attic, at the window, on the balcony, in the carport fixed to the wall or permanently attached to a mast. Flexible FM-band filter. Based on the well proven Mega Loop platform, an additional low pass filter and a FM-band filter were integrated which can be activated or deactivated with a jumper. In case of FM-interferences, the FM band 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 three-step amplification The gain of the Mega Loop FX can be adjusted in three steps by an internal jumper (High/Medium/Low) Frequency response (-3dB) and nominal amplification. a) FM-band stop off 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 on: 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 loop sizes The Mega Loop FX makes the most diverse radiating elements possible. As standard, a loop made of flexible PVC-coated and seawater-resistant (V4A) stainless steel wire is available. It comes as a 5m (16,40ft) circumference loop for indoor and portable as well as for outdoor use. Other lengths, such as 10m (32,81ft), are available as an option. Lengths up to 20m (65,62ft) have been tested successfully. Additionally, an aluminum rigid loop with a diameter of 40 cm or 80 cm is also available. Due to its versatility and adjustment of amplification, there will always be an ideal combination of the loop size and amplification. Excellent IP values with power supply as low as 5V. With two signals in the 7 MHz range, an excellent IP3 value of typ. +40 dB and a IP 2 value of +85 dBm is achieved with mere 5 V ( max. 40mA) and so the loop can be powered via USB or power bank. A DualPower power inserter (bias tee) supply is included.
Tripple surge protection of the active parts. Primary protection by gas arrester with 60V trigger voltage and a max. pulse leakage current of 1 kA (8/20µs) and by twofadditional integrated fast protection of max. 2 kV and 8 kV respectively. Additionally, the loop connections are connected to ground with high impedance to avoid static charges.
Low shipping costs – not a bulky item! Since the antenna can be shipped as such a small parcel, there will be standard postage only and when ordering a rigid loop of 1m or 2m diameter you will already have saved compared to shipping as a bulk item.
Hint: With two suction cups, you can attach the MegaLoop antenna to a window at home, at a hotel or when on the road. Because of its flexible loop, transportation is really 'a piece of cake'. In our newsroom test ” Design of a really portable SDR Part 2″ I attached the loop to the tailgate of our Caddy and was able to receive strong signals.
