The link http://active-antenna.eu/ is to the LZ1AQ loop amplifier.
The LZ1AQ amplifier is NOT a differential input amp, rather the input is referenced to ground. This can have significant issues as it relates to common mode noise. As a result of my research, I ended up with a Pixel loop. The amp has great characteristics, differential input, uses an A.C. wallwart for low noise, and the install instructions isolate the amp from any ground. The loop interface also has a control line input from your rig, that controls an internal relay, so the amp is protected when you transmit. The loop was designed by hams. The mechanical design of the loop is excellent, using welds at the aluminum joints. I have no interest in the Pixel company, just a very satisfied customer. So satisfied, I bought two of them and phase them with a DX Engineering NCC-1 phaser.

I use a 160 foot unterminated wire through a 6:1 binocular core transformer and feed it with 75 ohm coax. It is up about 4 feet off the ground. It works surprisingly well on 20 through 10 meters. It's performance is marginal on 30 and 40 but sometimes it helps with band noise. It may as well be a dead short on 80. It is not ideal in any case, but it was cheap and has helped with my horrible power line RFI problem.
