AOR antenna Shielded loop antenna LA400 Indoor shield loop antenna for receivin

Indoor shield loop antenna (for receiving only). Built-in 20dB low noise amplifier. The practical application of loop antennas dates back to the 1915 KOLSTER radio multi-winding loop antenna.

Loop antennas, especially active loop antennas, have become widely used and known in the 1970's for exploration and military use. In recent years, the increase in artificial noise (urban noise) has become an inevitable problem in long- and short-wave long-distance reception, and it is difficult to receive signals that should be heard due to the increase in noise. The LA400 is the latest product that has generously introduced the technology cultivated over many years from the LA320 compact loop antenna.

How to raise the signal from artificial noise (urban noise) and how to provide good reception, the technician's answer was to move the antenna away from the noise source and move the antenna as close to the aperture as possible. The LA400 has the industry's first remote control (remote control) function and is the antenna that has challenged this proposition. LA400 is a shielded loop antenna for receivers that covers 10kHz to 500MHz in 5 bands.

Although the loop diameter is as small as 30cm, it has a built-in low noise amplifier with 20dB gain to enjoy reception in an indoor environment. This is the first indoor loop antenna equipped with a remote control function that separates the antenna section from the control section. Use the optional extension cable set (10m) or a commercially available cable to tune and switch the antenna from a distance of up to 20m. By placing the antenna away from noise sources and near the window, a comfortable reception environment can be obtained. Relay system: For band switching, a full-scale switching circuit using a relay with excellent isolation is adopted.

The relay is built into the antenna itself and switches the reception range via a control cable. Electronic tuning: For 150kHz to 30MHz, sharp tuning can be obtained by the electronic tuning method.

The tuning point can be slightly shifted by operating the TUNING knob to adjust the attenuation and amplification of unwanted radio waves to bring them to the best reception condition. 150KHz to 30MHz (4 ranges). 10KHz 150KHz / 30MHz 500MHz. About 312 (W) x 425 (H) x 112 (D) mm. We are located in Japan. It's our pleasure to make you happy by proposing our recommend item.
