## Description

**RF Explorer** is a handheld digital spectrum analyzer - a convenient tool for work in all popular frequency bands. It's based on an integrated frequency synthesizer and double-balanced mixer which offers high performance, compact size, and low power consumption.
The RF Explorer has been designed for both indoor and outdoor, and can be connected to a PC for extra functionality using a standard mini-USB lead.
This model features a WSUB1G base unit with a RFEMWSUB3G expansion-module already assembled and tested. It comes with two SMA connectors and two antennas: a Nagoya NA-773 wideband telescopic antenna for Sub-GHz frequencies and a whip helical for 2.4GHz band. Additional, specific-band antennas may be needed to cover some of the frequencies supported.
