Lowrance GPS Antennas: Precision Position & Heading for the Water

When it comes to marine navigation, the quality of your GPS antenna can mean the difference between confident piloting and guesswork on the water. Lowrance has built its reputation as one of the most trusted names in marine electronics, and their GPS, Cellular & WiFi Antennas reflect the same engineering rigor found throughout their broader navigation lineup. Whether you're overlaying radar on a chart or maintaining precise course tracking in shifting conditions, a Lowrance GPS antenna module gives you the real-time data your chartplotter depends on.

The Point-1: A GPS Antenna That Goes Beyond Position

The flagship of Lowrance's external antenna lineup is the Point-1 GPS/Heading Antenna Module — and it stands apart from standard position-only antennas in a meaningful way. Unlike other position-only antennas, the Point-1 provides heading for accurate boat direction at any speed and for radar/chart overlay. That built-in heading capability is what makes the Point-1 especially valuable for boaters who rely on radar overlay and chart stabilization, functions that demand not just where your vessel is, but which way it's pointed.

The Point-1 supports GPS and GLONASS, is Galileo-capable with a future software update, and supports SBAS including WAAS, EGNOS, and MSAS. This multi-constellation approach means more satellite signals are available at any given time, improving fix reliability in areas with obstructed sky views — a common challenge in coastal inlets, marina slips, or under bridge structures.

10Hz Updates & Integrated Electronic Compass

One of the most important specs for any marine GPS antenna is its update rate. Equipped with an integrated electronic compass alongside GPS, the Point-1 provides accurate heading for stable chart orientation in Heading Up mode, improved Course Over Ground at low speeds, and radar overlay on your chart. The 10Hz update rate — ten position refreshes per second — means your chartplotter display stays fluid and current, even at higher vessel speeds where older 1Hz antennas would lag noticeably behind.

The Point-1 easily connects to any HDS Gen2, HDS Gen2 Touch, or Elite-7 display or any NMEA 2000® network, and is fully waterproof and can be pole or surface mounted on any boat. The included mounting hardware makes installation straightforward whether you're retrofitting an existing boat or setting up a new electronics station from scratch.

Lowrance LGC-16W: Dedicated Antenna for Elite & Mark Chartplotters

For boaters running Lowrance's popular entry-to-mid-range display lineup, the LGC-16W is a dedicated solution. The LGC-16W external Elite GPS Antenna is designed for Elite/Mark series chartplotters and includes a 20-foot cable. This makes it an ideal plug-and-play upgrade for anglers and cruisers who want to mount their GPS receiver in an unobstructed location away from the helm, maximizing signal quality without complicated wiring runs.

Why External GPS Antennas Matter on a Marine Vessel

Modern chartplotters often include an internal GPS receiver, but external antenna modules like those from Lowrance offer real advantages: they can be positioned for the clearest sky view on deck, away from electrical interference at the helm, and they can share position and heading data across an NMEA 2000 network, feeding multiple displays and instruments simultaneously. For serious navigators, an external Lowrance GPS antenna module is a smart investment in the accuracy and reliability of the entire onboard electronics ecosystem.
