CCW HF Active Loop Antenna

CCW HF 有源环形天线

The Cross Country Wireless HF Active Loop Antenna is a compact receiving loop with a frequency range of 200 kHz to 70 MHz with extended coverage up to 148 MHz. The antenna can be for all LF MW and HF professional monitoring and short wave listening. It can also be used for VHF FM reception and will give useful VHF airband reception when mounted outdoors.

越野无线HF有源环形天线是一款紧凑的接收天线，频率范围为200千赫至70兆赫并可以扩展覆盖148 MHz。该款天线可用于对所有LF、MW和HF频段进行专业监测和短波收听。它也可以用于甚高频调频接收并可以移动到户外进行甚高频航空波段接收。

Product Description

产品描述

The antenna is a triangular loop antenna 1.1m (51″) wide with a built-in low noise high dynamic range RF amplifier. A base unit allows 12V power to be fed up an ethernet cable feeder to the antenna. The antenna current consumption is 150 mA. The base unit also has a two way splitter to provide two separate RF outputs.

天线是一个三角形的环形天线，宽1.1 m(51英寸)，内置一个低噪声射频高动态范围放大器。基础单元允许12 v电源通过以太网电缆给天线供电。天线电流消耗是150 mA。基础单元也有两个分配器提供两个独立的射频输出。

Local RF noise rejection of the antenna allows it to be used indoors with good results where outdoor installation is prohibited. In addition to the excellent local noise rejection properties of the loop antenna transformer isolation common mode chokes and the balanced pairs in the ethernet cable help keep RF noise away from the antenna element.

有些地方不允许在户外安装天线，该产品的本地射频干扰抑制功能使得天线可以在室内使用，效果很好。除了优秀的本地干扰抑制特性，变压器隔离、共模堵塞和双平衡以太网电缆都成为使射频噪声远离天线的因素。

The antenna is built from fibre glass and stainless steel with a polycarbonate box housing the amplifier.

天线是由玻璃纤维和装在不锈钢聚碳酸酯盒子里的放大器组成。

The antenna can be quickly assembled and disassembled to allow portable operation from temporary listening sites with compact storage and easy installation in areas with restricted access.

天线可以快速拆卸和组装，不占空间，方便在临时的狭小场地架设收听。

BNC female connectors are used for the RF output ports on the base unit. RF over-power protection on the antenna and the RF outputs allow the antenna to be used very close (>2m) to transmit antennas and tolerate accidental connection of a transmitter to the RF output sockets for a short period (150W for 30 seconds) without damage. The antenna could be mounted on top of a rotatable HF beam as a low noise diversity reception antenna.

BNC母头连接器用于RF输出端口的基本单位。天线的射频过载保护和射频输出允许天线近距离接近(> 2 m)发射天线，允许偶然发射机的射频输出意外在短时间内不会损坏(150 w 30秒)。天线可以安装在一个可旋转的天线HF横梁上作为低噪声分离接收天线。

In the box

• Hardware for a 1 meter triangular loop

• Mounting kit with fittings for mounting on 50mm (2″) or 25mm (1″) diameter masts
