Special note: This antenna is an active receiving antenna and cannot be used for transmission. Transmission will damage the preamplifier (in the box below the small ring)!!! Do not randomly connect other power sources for power supply. The input end of the small loop cannot be connected to other types of antennas (only the small loop can be connected), otherwise it may also damage the preamplifier!!! Remember! Remember! Remember!
K-180WLA is an active ring broadband receiving antenna (radio full band antenna) originally designed by myself. The P.BOX feed box is equipped with a 3.7V 18650 flat head lithium battery integrated with a power supply module, which is the only active antenna that does not require external power supply. It also integrates a charging management chip and is compatible with Android phone 5V charging head and cable using a MICRO USB charging port, making it very convenient to use. The Super high frequency low-noise preamplifier is adopted, and the gain flatness within the ultra wide operating frequency 0.1-180MHZ operating bandwidth is very good, providing about 20DB gain. Even if the operating frequency reaches 450MHZ, there is still about 8.9DB gain. The reception frequency covers the long wave, medium wave, short wave, FM broadcasting bands, and VHF aviation bands. The small ring diameter of 55CM is easy to install, and can be installed outdoors, on balconies, terraces, and rooftops. There is no obstruction around, making it the best choice for broadcasting enthusiasts with limited space to install. All screws of the antenna are made of 304 stainless steel material, and the front amplifier box is a fully waterproof structure that can be installed outdoors in wind and rain for long-term use. Suitable for use with all short wave receivers such as Desheng S-2000 PL-660 PL-880 ICOM R71E YAESU FRG-8800, especially very suitable for SDR receivers. This antenna is a receiving antenna and cannot be used for transmission. Remember!!
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. This means that your radio can be used with SMA female, BNC socket, and 3.5 jack, without the need to purchase other accessories. Receivers and radios with other interfaces must have their own adapters.
