Улучшенная версия активной петлевой широкополосной приемной антенны K180WLA 0.1МГц-180МГц 20дБ SDR FM антенна LOOP малая петля HF.

Description

The latest upgrade and improved version of K-180WLA (the input terminal adds a protection circuit and improves the anti-static ability and induced lightning). All orders are given a free Tecsun S2000 adapter, and all orders are given as a gift of BAK 1,000-cycle charging 18650 2750MAH battery (installed in the blue In the color P.BOX box, use the 5V charging head of the mobile phone to charge), because the antenna assembly test is very time-consuming and laborious, it is sent away after the assembly test is completed.

Special note: The antenna has to undergo more than three rigorous tests before and after assembly. Therefore, it is 100% guaranteed that the antenna specifications are qualified and perfect before shipment. In addition, this antenna is an active receiving antenna and cannot be used for transmission. The transmission will damage the preamplifier (in In the box under the ring)! Do not connect other power supplies randomly, and the small loop input terminal cannot connect to other types of antennas (only small loops), otherwise the preamplifier may also be damaged!

K-180WLA active loop antenna parameters:

1. Using ultra-high frequency low noise preamplifier

2. Ultra-wide working frequency: 0.1-180MHZ

3. The gain within the working broadband is about 20DB

4. Working voltage: DC 5V-12V

5. P.BOX has: anti battery reverse connection, over discharge, over charge, over current

6. 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 chip. 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 flatness 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 stainless 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 accessories. Receivers and radios with other interfaces need their own adapters.
