HamGeek 100K - 180MHz K-180WLA New Active Radio Shortwave Antenna Full Wave Band SDR LOOP Antenna with 10m Feeder

Description:
- The K-180WLA enhanced version has a small ring with a diameter of 68CM and a low battery indicator is added. The 2023 new version of the preamplifier has replaced the imported RF amplifier with better parameters and lower noise figure (non-low-end video amplifier IC), higher receiving dynamics and signal-to-noise ratio, lower noise figure, and can withstand -10DBM signal strength Unsaturated, the feeder is upgraded to LMR100 96-braided pure copper densest mesh plus aluminum-platinum double-shielded feeder and K-180 customized ultra-low loss feeder 112 braided pure copper densest mesh plus aluminum-platinum double-shielded feeder for better shielding loss Smaller, feeder SMA males replaced with anti-extraction pins.

- The new version of the preamplifier adds the FMDX HF switch to adjust the FM band gain (the FM band gain is reduced in the FM strong signal area, and the HF band gain is increased, and the new version of the feed box has three levels of gain adjustable).

- The feed box is equipped with a 3.7V 18650 flat head lithium battery, which integrates a power supply module. It is the first original designed active antenna without external power supply, and integrates a charging management chip. The MICRO USB charging port is compatible with the 5V charging head and cable for Android phones, making it very convenient to use. Using ultra-high frequency low noise preamplifier devices (non video amplification ICs), the gain flatness within the ultra-wide operating frequency range of 0.1-180MHz is very good, providing about 20DB gain. Even when operating at 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 antenna is simple to install, and can be installed outdoors, on balconies, terraces, and rooftops, suitable for broadcasting enthusiasts with limited space. 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 models include for Tecsun S2000, S8800, PL-330, PL-365, PL-660, PL-880, PL-990; for Sangean 909X; for ICOM R71E; for YAESU FRG-8800 and all other shortwave receivers, especially suitable for SDR receivers. This antenna is a receiving antenna and cannot be used for transmission.

Precaution:
- Please ensure that your radio has a corresponding band external antenna port, and radios with only a pull rod that does not have a corresponding band external antenna input port cannot use. (Radios with high impedance external antenna ports such as old antique electronic tubes, wiring posts, and wiring clips, such 300 to 500 Ohms, cannot operate normally)
- 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 it supports radios 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. What is more, a small bottle of PVC adhesive (not included) must be provided when installing the antenna.
