Description:

MLA-30+ Loop Antenna Active Receiving Antenna 500kHz - 30MHz for Short Wave RadioType: Loop AntennaModel:MLA-30+Frequency coverage: 500kHz to 30 MHz

Note: The reception performance of the upgraded version is much better than that of the old version. For the accuracy of the antenna parameters, we start marking from 500kHz, which means 500kHz to 30 MHz. We can guarantee that it will have a good reception effect within this range. 0.1-500khz can also be received, and the reception effect of 0.1-500khz depends on your location. Therefore, the 0.1-500khz frequency band can be received. It does not mean that we have cancelled the reception capability of this frequency band.

Features:

1.The MLA-30+ is a toroidal magnetic antenna.2. The MLA-30+ loop antenna is a popular broadband antenna. It is an effective antenna for short-wave listeners (SWL) and amateur radio enthusiasts (HAM) to receive medium-wave and short-wave in the limited living area of the city. Frequency coverage: 500kHz to 30 MHz. Excellent directionality can help you reduce noise and improve signal-to-noise ratio, and can dig out weak signals that are overwhelmed by noise when conventional antennas are received.3. The MLA-30+ loop antenna is easy to install and can be easily installed on balconies, rooftops, and other small, compact, low-profile installations without worrying about neighbors and property opposition.4. Another advantage of the MLA-30+ loop antenna is that it is directional. By rotating the antenna so that the dummy point of the antenna is aligned with the interfering signal, the specific near-field interference can be minimized.5.Details of the MLA-30+ loop antenna:①. Do not connect it to the transmitter as it will cause the preamplifier to be damaged.②. Local radiation noise suppreion up to 30 dB compared to long-haul antennas③. 8-shaped patterning provides deep dummy points tother reduce interference④. USB power supply, convenient to take power. S-contained feeders simplify the installation proce.⑤. Simple structure, easy to install to the balcony, rooftop and other locations.⑥.No manual adjustment required⑦. Install low-key, no need to worry about neighbors and properties.⑧. Modular design, easy to install and maintain.⑨. Stainle steel ring , easy to install and easy to maintain.⑩. Rainproof enclosure for long-term fixed outdoor use.⑪. Main coverage: 500kHz to 30 MHz Note: The reception performance of the upgraded version is much better than that of the old version.

K-180WLA active loop antenna parameters:

1. Using ultra-high frequency low noise preamplifier2. Ultra-wide working frequency: 0.1-180MHZ3. The gain within the working broadband is about 20DB4. Working voltage: DC 5V-12V5. P.BOX has: anti battery reverse connection, over discharge, over charge, over current6. Short circuit at the antenna end improves the protection circuit

Feature:

1.The P.BOX feed box has a built-in 3.7V 18650 flat-head lithium battery with integrated power supply module. It is the only active antenna that does not require an external power supply and integrates a charge management . The MICRO USB charging port is compatible with the 5V charging head of Android phones. And charging cable, very easy to use. 2.UHF low-noise preamplifier is used. The gain flatne is very good within the ultra-wide operating frequency of 0.1-180MHZ. It provides a gain of about 20DB, even when working to 450MHZ gain, there is still about 8.9DB. 3.The receiving frequency covers long wave, medium wave, short wave, FM broadcasting band and VHF aviation band. The small ring diameter 55CM is simple to set up. It can be set up outside the window, balcony, terrace and roof. Lovers erected. 4.All the screws of the antenna are made of 304 stainle steel, and the preamplifier box is fully waterproof, which can be used for long-term outdoor wind and rain. 5.Suitable models include Desheng S-2000 PL-660 PL-880 ICOM R71E YAESU FRG-8800 and all short-wave receivers, especially for SDR receivers.

Note:

The antenna is equipped with a dual SMA male adapter cable, an SMA to 3.5 plug adapter cable, and an S2000 BNC adapter, which means that your radio can be used with SMA female, BNC, and 3.5 jacks. Requires additional acceories. Receivers and radios with other interfaces need their own adapters.
