Compact HFDY Active Small Magnetic Loop Antenna For HF Short Wave AM FM VHF UHF

DESCRIPTION Features: * Brand new and high quality * Made of high quality materials, * The for SMAll loop antenna (hfdloop) is a for SMAll-sized full-band ring magnetic field active receiving antenna with a receiving frequency range of 50kHz to 500MHz. It mainly consists of a top for JUMPER board, a for SMAll loop amp lifier board, a for SMAll loop coil, a feeder, a feeder and a 12V It is composed of a linear power supply. There are several sets of switches on the top for JUMPER board and the for SMAll ring amp lifier board. By adjusting the positions of the switches, for SMAll loop antennas of different structures can be realized. Among them, the M?bius strip can achieve twice the voltage gain of ordinary for SMAll rings. ; The electric field shielding ring can effectively reduce the interference caused by the electric field in the surrounding environment, such as ligh tning, electrostatic discharge, .; the non-shielding ring has a simple structure, and the entire for SMAll ring can be replaced by a thier wire. The size is simple to modify and easy to erect. Specification: 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 Supply current: 130mA to 150mA Antenna interface: for SMA(M) Output interface: for SMA(F) for SMAll ring coaxial cable model: RG402 for SMAll ring coaxial cable loss: 0.145dB/m for SMAll loop antenna diameter: 60cm Package Included: 1 x for SMAll loop antenna amp lifier board, 1 x headphone ja adapter cable, 1 x top for JUMPER board 2 x for SMAll toroids (RG402 coaxial cable) 1 x 7m feeder 1 x 1 meter feeder 2 x stiy hooks 1 x EVA storage bag Note: 1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness. 2.Please allow slight manual measurement deviation for the data.
