I recently stumbled upon the Active Antenna Amplifier (model AAA-1C) by LZ1AQ. At 87.00 EUR, it’s a pretty affordable and flexible solution for those who would like to design or use a loop antenna. 我最近偶遇 LZ1AQ设计的有源天线放大器 (型号 AAA-1C) ，价格：87.00欧元，这是一个负担得起的价格，对于那些想设计或使用环形天线的爱好者提供了灵活的解决方案。 
According to the website, it packs a lot of features: 根据官网信息，该套件有以下特点： 4 remotely switched modes (Loop A, Loop B, crossed parallel loops A&B and dipole) 4种远程切换模式(B循环,循环交叉并行循环方式和偶极子) Each mode can be switched immediately 每一个模式都可以立即切换 Good sensitivity and a flat frequency response 良好的灵敏度和平坦的频率响应
High dynamic range 高动态范围
Protected input from strong signals 强信号输入保护 High immunity to local noise with balanced amplifiers and balanced feed line 通过平衡放大器和平衡馈电线对本地噪音进行抑制
Balun transformer coupling for common mode noise reduction 采用平衡变压器对共模噪声进行降低
Extensive documentation manuals with detailed description how to build your own small antennas 包含文档手册详细描述如何构建自己的小型天线
The amplifier is described as a kit because you must mount the board, wire up the antenna and set up remote switching yourself. It appears the SMT board comes pre-populated, though so I’m not sure if any actually soldering is required (perhaps someone can verify). 该放大器根据产品描述是套件，你必须自己安装主板，连接天线并设置远程切换开关。似乎SMT板已经预填充，所以我不确定是否需要任何实际焊接(也许有人可以验证)。 I’m tempted to purchase one this winter for use on mediumwave. 我打算购买一个用在这个冬季的中波的接收上 Click here for more info about the AAA-1C at LZ1AQ’s website. 想了解AAA-1C 的更多信息，请登录LZ1AQ的网站： http:///amplifier-kit/ 奉上全英文说明书
