RF Explorer is a handheld digital spectrum analyzer, a very affordable tool for work in all popular frequency bands. It is based on a highly integrated frequency synthesizer
and double balanced mixer which offers high performance, compact size, low consumption and low cost. It has been designed to be used equally well outdoor and indoor, and can
be connected to a PC for extra functionality using standard mini-USB 2.0 connector.

This model includes a WSUB1G baseline unit plus an RFEMWSUB3G Expansion Module conveniently assembled and tested. It comes with two SMA connectors and two antennas, a nice
Nagoya NA-773 wideband telescopic antenna for all Sub-GHz frequencies and a whip helical for 2.4GHz band. Additional, specific band antennas may be needed to cover
efficiently some of the frequencies supported.
