TF908 Directional Antenna System

A portable signal location and measurement device for radio monitoring, signal detection, and EMC testing, etc.

Highlights

Four directional antennas cover from 9kHz to 8000MHz, meeting the needs of full-band signal testing
Built-in amplifier with a typical gain of 16dB, effectively improving signal reception sensitivity
Accurate directional positioning : cardioid linear pattern, front-to-back ratio better than 6~16dB, combined with a three-dimensional electronic compass, real-time display of the signal source direction
The antenna and handle are lightweight, with a total weight of only 7.5kg (including packaging), suitable for field and mobile operations
The handle integrates a “start measurement” button, which supports one-button triggering and is easy to operate
Support USB or aviation plug power supply, SMA output interface is compatible with most test equipment
Includes F20/F225/F250/F580 Antenna and W3 Smart Handle
