K-480WLA Medium/short Wave/FM/aviation/UVHF Full Band Antenna SDR LOOP Small Loop Short Wave Antenna

only RX, can't TX

K-480WLA is an active ring broadband receiving full band antenna originally designed by myself (a full band antenna with built-in six band high-performance low-pass, bandpass filter, and MW medium wave FM frequency modulation bandstop filter). It is also the first active antenna with built-in filter originally designed for the entire network, which can selectively receive signals in designated frequency bands to suppress out of band interference! Make the reception effect clearer, providing seven reception modes: full band, MW (medium wave), SW (short wave), FM (frequency modulation), AIR (aviation band), 6m (amateur band), UV (UHF-VHF band), with a built-in 7.4V lithium battery and integrated charging management chip. The TYPE-C charging port is compatible with the 5V charging head and cable of the phone, making it very convenient to use. Adopting ultra-high frequency low noise amplification devices (with a maximum operating frequency of 1GHz), the gain flatness within the ultra-wide operating frequency range of 0.5-500MHz is very good, providing approximately 0-30DB gain (continuously adjustable gain). The reception frequency covers the medium wave, short wave, FM broadcasting bands, and UHF-VHF aviation bands. The small ring diameter of 68CM is simple to install, and can be installed outdoors, on balconies, terraces, and rooftops. It is suitable for broadcasting enthusiasts and amateur radio enthusiasts with limited space to install. All screws of the antenna are made of 304 stainless steel material, and the front passive matching box is a customized black fully waterproof structure for outdoor use in wind, sun, rain, and long-term installation. Suitable models include the Desheng S series S2000 S8800 and the PL series PL-330 PL-365 PL-660 PL-880 PL-990 Shanjin 909X 909X2 ICOM R71E YAESU FRG-8800, which are suitable for shortwave receivers and radios with external antenna ports in all corresponding bands (many applicable models are no longer listed one by one), especially suitable for SDR receivers,This antenna is a receiving antenna and cannot be used for transmission. Remember!!

Antenna has been patented and copying is mandatory!!

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, or 3.5 jack, without the need to purchase other accessories. Receivers and radios with other interfaces should be equipped with corresponding adapters(When installing the antenna, you should bring a small bottle of PVC glue). For those who are not familiar with the interface type, you can consult first.

For after-sales maintenance and express delivery, please refer to the final note:

The antenna includes a circular oscillator (made of 304 stainless steel), a black front matching box, a host control box, two front matching box fixed back clips and four screws (made of 304 stainless steel), a dual SMA male adapter cable (one meter long), an SMA male to 3.5 plug adapter cable (one meter long), and TYPE-C  One 3A charging line (one meter long), one TNC male and SMA male customized K-180 ultra-low loss feeder line (5-30 meters in length can be freely selected in the package). This feeder line has the same performance as the American standard 302 feeder line, and the antenna is installed with two fixed clamps (made of 304 stainless steel material). Provide 4 PVC installation brackets, 3 straight joints, and 1 20 pipe cap as a gift.

The K-480WLA uses a 50 ohm customized version of the K-180 ultra-low loss feeder. Note: K-180 is a feeder model with a diameter of approximately 3.5mm, which has the same performance as the standard American 302 feeder.

Desheng PL series PL-600 PL-660 PL-880 990 and Shanjin 909X2 radios use 3.5 plug patch cords, one end is an SMA male and the other end is a 3.5MM plug (gold-plated high-quality plug is selected) and the double SMA male patch cord (used by SMA connector SDR receiver) has a patch cord length of 1 meter, both of which are 96-coded shielding nets and 50-ohm feeders.
