Our take on the Laird Technologies 4G/3G Multiband No Ground Plane Phantom Antenna

The Laird TRA6927M3PBN Phantom is a dome-shaped multiband antenna for 4G and 3G cellular networks. Its key trait is that it needs no ground plane, so it works on fiberglass boats, RVs, plastic enclosures and other mounts where a metal surface is missing. It uses an N connector and handles up to 100 W. It suits people setting up a cellular modem, router or booster in a vehicle or remote site. Compared with typical whip antennas, it trades a little gain for a low, sturdy, weather-friendly dome that mounts with a single hole.

Questions and answers

Does it really work without a ground plane?
Yes. It is designed for mounts like fiberglass, plastic and wood where no metal ground plane exists. Performance is best with a clear view of the sky.
Will it connect to my home router or modem?
Only with an adapter. The antenna has an N connector, while most consumer modems use SMA or TS9, so plan on an N-to-SMA cable.
Does it support 5G?
It covers 4G and 3G bands. It is not a millimeter-wave 5G antenna, though it can serve low-band 5G on some networks.
How is it mounted?
It mounts through a single hole in the surface, with the cable run below. That gives a low, snag-free profile.
Is it suitable for a boat or RV?
Yes. The no-ground-plane design and sealed dome suit marine and vehicle use, and the N connector holds up outdoors.
