– DISCONTINUED PRODUCT –
Magnetic loop antenna for reception only
FEATURES:
- Ultra-wide reception range 10kHz 〜 500MHz. Four band selectable between 150kHz 〜30MHz and precisely tunable for best receiving experience. Sharp alignment characteristics by electronic tuning. Exceptional 20dB gain thanks to built-in low noise amplifier.
- Shield loop antennas have the advantage, over non shielded ones, to be very robust against local noise from electrical devices such as televisions, PCs, fluorescent lightening, switching power supplies, etc…
- 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 optional LA400-RCK 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.
- 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 150kHz〜30MHz allows very sharp tuning to the desired frequency. Shift the aligning point slightly to attenuate unwanted signals while amplifying the wanted signal.
- Any type of receiver – LA400 can accommodate not only any kind of communications receiver between 10kHz and 500MHz, but also your beloved antique vacuum tube receivers, especially with option MC-600 described on the right side. Can also be used as an antenna for portable FM radios, while improving tuner performance (selectivity).
