AOR LA-350 Loop Antenna

Active Loop Antenna

AOR has just released a wide-frequency-coverage loop antenna system for indoor reception of long wave, medium wave, and short wave signals. Currently supplied with loops for 3-9 and 9-30 MHz. Additional loops for 200-540 kHz and 540-1700 kHz can be ordered as options.

Utilizing an internal 13.5 dB gain amplifier with an impressive +30 dBm third-order intercept, the pattern is quite sharp, and the frequency-tunable amplifier offers good selectivity.

The loop is enclosed in a rigid aluminum Faraday shield to reduce pattern-distorting capacitance effects. Our lab test verified a sharp loop pattern which easily discriminated between desired signal paths and ambient noise sources, as well as separating incoming co-channel signals.

The loop is mounted on a conventional 1/4" audio plug which swivels into the host jack on the top of the control box. Power is supplied by 12 volt wall adaptor, inviting battery operation for hum-reduction requirements. A 20" BNC/BNC coax interconnect cable is included; this will require the after-market purchase of a suitable adaptor for virtually any receiver external antenna connector.

Key features

• The LA350 is a new short wave desk-top active loop antenna.
  

• The LA350 is supplied with the two (2) interchangeable antenna elements as standard covering 3.0 ~ 9.0 MHz and 9.0 ~ 30.0 MHz loop (12 inches diameter).
  

• The LA350 has a tuning control to peak performance and elements may be rotated to enhance reception and hull unwanted interference.
  

• The LA350 has a built-in high gain (13.5 dB) signal amplifier and has a high IP3 (+30 dBm).
  

• The LA350 is ideal to place in a suite-case for occasional traveling. Two additional bar antenna elements are available as options to further extend the operation frequency coverage.
