This is a broadband galvanic antenna isolator. A high quality transfomer permit the use from LW up to the UHF frequencies.
A ground loop in your receiver caused by antenna connection is very common if you have your computer connected to the same system. This type of ground loop problem can be solved by using suitable isolation between your receiver and the antenna cable.
The pcb accept also other transformers with different ratio follow packages (case style): SM22, KK81, W38, X65. There exist also the possibility to mount SMA, SMB or MMCX connectors.
In/out impedance : 50 Ohm (1:1 ratio)
Insertion loss: max. 1dB (2-50 MHz) / 3 dB(0,15-400MHz)
Maximum RF Power : 0,25W
