Description:

The small loop antenna (hfdloop) is a small size full band ring magnetic field active receiving antenna

To 500MHz, mainly composed of top jumper board and small ring amplifier board

Feeder and 12V linear power supply, in which the top jumper board

Switch, different functions can be realized by adjusting the position of the switch

The Mobius loop can achieve twice the voltage gain of the ordinary small loop

The electric field shielding ring can effectively reduce the interference caused by the electric field in the surrounding environment, such as lightning

The structure of unshielded ring is simple, and the whole small ring can be replaced by a thicker conductor

Easy to erect. The installation and connection mode of flying fish version small loop antenna is shown in the figure below

Antenna,

Small ring enlarged plate,

Top jumper board

Different junctions can be realized at different positions, in which Mobius ring can realize twice the voltage gain of ordinary small ring static electricity

Technical specifications:

Receiving frequency range: 50KHz to 500MHz

Gain: 17dB@10MHz

Output noise: - 125dbm (@ 10MHz, BW = 100Hz)

P1dB：+15. 5dBm@10MHz

OIP3：+ 38dBm@10MHz

Supply voltage: 9V to 12V

Power supply current: 130mA to 150mA

Antenna interface: SMA (m)

Output interface: SMA (f)

Small ring coaxial cable model: rg402

Loss of small ring coaxial cable: 0.145db/m

Small loop antenna diameter: 60cm

Package size: 380x300x80mm

The small ring as a whole can be replaced by a thicker wire, as shown in the figure below

The small loop antenna consists of a small loop amplifier, a feeder and a top

1 jumper board, 2 small loop coils (rg402 coaxial cable), 1 5m feeder, 1 1m feeder, 1 12V linear power supply and 2 traceless adhesive hooks.

The amplification board in the flying fish version small loop antenna adopts the low-noise amplification of the improved version lz1aq

The bandwidth is from 50KHz to 500MHz, the gain is greater than 10dB, and has low bandwidth

The input impedance (1.2 Ω @ 1MHz) effectively reduces the electric field interference. 12V linear

Power supply, current not exceeding 150mA.

The specific test curve of the amplification board is shown in the figure below:
