Description

Ultra low noise active ring resonant antenna

All new tuning large loop antenna, low noise, natural resonance tuning, multistage amplification, tuning / broadband mode, medium wave filter, all in one! Specially designed for resonant antenna lovers, enjoy the DX fun brought by low noise receiving and tuning!

The antenna consists of amplifier and controller

The amplifier can be installed outdoors and connected with the terminal by the flexible cable ring. The size of the ring can be adjusted freely. 3-8m perimeter is recommended; The amplifier unit and controller unit are recommended to use cat7 standard double shielded network cable to connect to the home to shield the environmental interference as much as possible.

The controller unit consists of five switch, namely: power supply, preamplifier, tuning / broadband mode switching, medium short wave switching and medium wave filter switching. The tuning part has two tuning controller units: tuning and fine tuning knob. After coarse tuning, the fine tuning knob can be used for more accurate resonance tuning. The power supply voltage of the controller is 12-15v / 200mA (positive inside and negative outside), and the BNC port is connected with the receiver.

The working principle of the antenna is tuning natural resonance plus amplification, which can switch between tuning and broadband modes. In addition, it is equipped with a pre amplifier of about 15dB to make up for the lack of gain in broadband mode, or a weak signal secondary amplifier in tuning mode to tune and adjust by viewing the signal peak value through the spectrum, and finally turn off the pre amplifier. Strong signals turn off the preamplifier for a better listening experience.

MW fliter switch can attenuate the middle wave band to reduce the interference to the short wave and low frequency band.

The amplifier unit has been treated with glue and waterproof treatment. It can be installed outdoors with professional support pole and antenna rotator, or indoor with tripod. The ring can be connected to the amplifier terminal with multi-core flexible wire and coaxial feeder of different specifications.

The kit includes:
