An external 4G 5G antenna can move the radiating element outside a crowded device enclosure. The VLG R306 and SD6601 antenna documents describe compact rod-style options for IoT gateways, monitoring equipment and connected terminals. Their listed band ranges and cabled connection are the useful starting point for selection.

Compare the documented models
The supplied family comprises V2359-001-A-01, V2341-001-A-01 and V2341-001-A-02. Their specification tables list the same principal electrical ranges and package dimensions. Confirm the released drawing for the mechanical and harness differences before ordering a specific version.
Select by frequency rather than a broad 5G label
The specified cellular ranges are 700–960, 1710–2690 and 3300–3800 MHz. They are not continuous 700–3800 MHz coverage and do not establish compatibility with every sub-6 GHz band. Match the modem, network and operating configuration to those ranges.
Use the actual connector specification
These variants list a 173 mm cable and an I-PEX connection. They should not be advertised as directly interchangeable with every SMA or RP-SMA screw-on antenna. Confirm the exact I-PEX mating family, device-side routing and assembly access.
Test external placement on the gateway
Place the radiator where surrounding metal does not severely obstruct it, then evaluate the complete unit. Keep cable loss and connector loading under control. An omnidirectional design does not remove the effects of orientation, nearby objects or the final equipment enclosure.
Frequently asked questions
Can one of these replace four antennas on a 5G router?
No. A single-feed wideband antenna does not replace multiple independent modem antenna paths.
Are the three model numbers interchangeable?
The principal specification tables are similar, but use the final drawing and part specification to establish version compatibility.
