The GSM 6DBI Magnetic Mount Spring Antenna covers a frequency range (the band of radio waves it receives and transmits) from 698 to 2700 MHz. That range includes 2G, 3G, and 4G bands used across India and most other countries. The gsm magnetic wireless antenna connects to your module through an SMA male (a standard threaded RF connector) and delivers 6 dBi (decibels isotropic) of gain — that means it picks up a noticeably stronger signal than the short stub antennas usually included with GSM modules.
The 6dbi SMA antenna has a springy design, which is a practical detail worth understanding. A rigid antenna can snap at the connector joint if the cable gets tugged during deployment. The spring at the base absorbs mechanical stress and keeps the connector intact. One honest limitation — at 6 dBi this is a directional gain antenna, not omnidirectional. Signal peaks along the antenna’s vertical axis, so it sideways in a tight enclosure reduces effective gain. The 3-metre cable length gives you freedom to mount it on a metal surface while keeping the module inside a box.
The external GSM antenna for SIM800 module connects to SIM800L, SIM800C, SIM900A, and any module with an SMA female port. IoT developers, and engineering students working on remote monitoring projects. To start, with the SMA male connector firmly onto module’s antenna port — finger-tight is enough, do not overtighten. Provide by StemVolt, this unit is well suited for engineers building cellular IoT systems and practical wireless electronics projects.
