Since the invention of this revolutionary concept by KOLSTER in 1915, loop antennas, especially of the active type, have also been widely used by the military in the 70’s, before becoming very popular among hobby listeners.     

In recent years, the increase in man-made local noise (typical city noise) poses a problem for the reception of distant signals in the long wave, medium wave and shortwave bands. LA400 is our latest product based on the technology we developed since the original LA320 loop antenna. In addition to its exceptional directivity in order to minimize the effects of local noise, the revolutionary LA400 offers, with its REMOTE TUNING SYSTEM, the perfect solution to keep the antenna away from noise sources by setting it up in quiet areas! While the control (tuning) box stays at hand’s reach, the loop element can be set away by using simple LAN and BNC coaxial cables.   

10kHz to 500MHz, 5 position band switch to peak only on the wanted signal. Small size 30.5cm diameter loop with exceptional 20dB gain

Remote tuning – Unlike previous amplified indoor loop antennas, the band switching and fine tuning controls are not tied anymore to the loop element. With these controls now on the control box and by using the LA400-RCK optional extension cables, it is now possible to tune the antenna while the loop element is setup at the most reception friendly location possible (window, covered balcony, etc…). Compatible with 3rd party cables. Maximum length: 20m. (Minimum input voltage 12V when using an extension)

A relay system is used for band switching, providing excellent isolation characteristics. The relay is efficiently placed inside the loop element, while you can operate it through the control box via the control cable.

Electronic tuning from 150kHz30MHz allows very sharp tuning to the desired frequency. Shift the aligning point slightly to attenuate unwanted signals while amplifying the wanted signal.
