K-180WLA is upgraded again without price increase. The 10-meter-length feeder is upgraded to aluminum platinum plus pure copper dense mesh double-shielded feeder, which has better shielding effect and lower loss. The latest version of the preamplifier adds FMDX HF switch to adjust the FM band gain (FM The strong signal area reduces the gain of the FM band and increases the gain of the HF band).

K-180WLA (upgraded and improved version) has higher receiving dynamics and signal-to-noise ratio, and can tolerate -10DBM signal strength unsaturation. This is an indicator that the copycat version will never reach, all original design and manufacture!
P.BOX has: anti-reverse battery protection, over-charge, over-current, short-circuit protection at the antenna end, complete protection circuit, all the shells are numerically-precision processed, PCB high-frequency design, feeder high-density dense copper pure copper 50-1.5 feeder, materials used Create an ultra-high cost-effective antenna for the entire network.
P.BOX has a built-in 3.7V 18650 flat head lithium battery. No external power supply is required. The MICRO USB charging port is compatible with 5V charging heads and charging cables of Android phones. Convenience. 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. 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. It is best not to be surrounded by the surrounding area. It is very suitable for broadcasting with limited space. Lovers erected. 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. 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 for other interfaces need their own adapters.
The antenna includes a ring oscillator (304 stainless steel), an RF.BOX preamplifier box, a P.BOX feed box, two P.BOX fixing clips and screws (304 stainless steel), and a dual SMA male adapter One (one meter in length), one SMA male to 3.5 plug adapter cable (one meter in length), one Micro USB 2A charging cable (one meter in length), one TNC male and SMA male 50-1.5 feeder cable (10 meters in length) ), Two antenna fixing brackets (304 stainless steel). Free 3 PVC mounting brackets, 2 butt-throughs and 1 tube cap.
K-180WLA antenna installation and usage instructions
K-180WLA is a wideband loop receiving antenna. The preamplifier uses ultra-high frequency low-noise devices. The noise is low and the gain is about 20DB. The small loop diameter is 55CM. The excellent receiving directivity can effectively avoid interference sources and make the received signal clearer and more effective. Improve the received signal strength and signal-to-noise ratio. The working frequency is 0.1MHz-180MHz covering the long-wave, medium-wave and short-wave, FM broadcasting and VHF aviation bands, and the working voltage is DC 5-12V. The charging voltage of P.BOX is DC 5V (remember not to charge higher than this voltage, otherwise it may damage the circuit and other risks!), the charging interface is a MICRO USB socket (common with the 5V charging head and data cable of Android phones), and the charging current is 1A Fully automatically stops. The output voltage of the feeder box is 9V, and the internal isolation circuit is designed to effectively suppress in-band interference and make the output DC voltage more pure. A built-in 3.7V 18650 flat-head lithium battery, the feed box has: overcharge, overcurrent, overdischarge protection and short circuit protection of the antenna feed output terminal.
The receiving direction of FM and aviation band VHF is as shown in the figure below. The receiving direction of HF shortwave is reversed by 90 degrees and opposite to VHF.
