Victron Energy Outdoor 2G/3G GSM Antenna for GX GSM & GX LTE
Free shipping over $49
60-day hassle-free returns
An outdoor screw-mount antenna that boosts the cellular signal for a Victron GX GSM or GX LTE modem — ideal when the modem is mounted below decks, inside a metal enclosure, or anywhere reception is weak. Mounting it outside typically lifts signal strength substantially, keeping your system reliably connected to the VRM portal. It's tuned for 2G and 3G and also works on 4G.
