Overview
Stay connected offshore with the Go-Marine 5-Band Signal Booster, made specifically for boats, yachts, commercial marine vessels, fishing trawlers, and offshore operations. This powerful booster enhances 3G, 4G, and supported 5G signals across five major mobile frequency bands:
700 MHz (Band 28)
850 MHz (Band 5)
1800 MHz (Band 3)
2100 MHz (Band 1)
2600 MHz (Band 7)
This ensures stable voice calls, text messaging, and high-speed mobile data even when sailing far from shore.
The booster complies with Radio Spectrum Management (RSM)'s technical requirements, featuring:
Automatic Gain Control (AGC)
uplink/downlink shutdown Protection
Strict emission and interference control
Network-safe operation
Perfect for coastal cruising, marinas, offshore work vessels, and open-water travel, the Go-Marine delivers stronger reception, improved data speeds, fewer dropped calls, and multi-device support. Its corrosion-resistant, vibration-tested design is engineered for salt spray, humidity, deck vibration, and marine temperature fluctuations.

Ideal for fishing vessels, leisure boats, charter yachts, ferries, and offshore crews
Compatible with all major New Zealand networks (Spark/OneNZ/2Degrees)
Signal Requirement
A minimum outdoor signal of -100 dBm is required for boosting. Stronger outside signal = stronger boosted coverage inside your vessel.
Virtually none. Signal boosters are built to run continuously without adjustments. Once installed, they work automatically. The only thing you might need to check occasionally is that the outdoor antenna is still secure after severe weather, but beyond that, they just get on with the job in the background.
It is. Large steel buildings are well known for blocking mobile signal. A properly installed booster can distribute coverage across big spaces like woolsheds, workshops, or barns. The device will connect to an external antenna where signal is stronger and relays it inside, so you’re not left without reception when you need it most.
Yes, it will. Mountains and hills often obstruct the direct line of sight between your phone’s antenna and the nearest mobile tower. Since signals travel in straight lines, if a large object such as a ridge or hillside is in the way, the transmission may be absorbed or scattered.
A booster solves this issue by capturing whatever signal is available outside, even if it is weak or reflecting from nearby surfaces, through an external antenna. It then amplifies that signal and spreads it across the interior. So in mountain areas where your phone has difficulty, the booster works with the weak signal to provide you with stronger coverage throughout your home.
Yes, they do. 4G signal boosters can take the signal already reaching your property and make calls clearer, internet faster, and streaming smoother.
For 5G, 5G signal boosters designed for New Zealand bands can boost low, mid, or high-band coverage indoors. Even if you mainly use 5G, strengthening the underlying 4G signal can still improve overall performance for calls, apps, and data.
Setting up a booster is pretty straightforward. First, stick the outdoor antenna somewhere it can grab the best signal, usually on the roof, a balcony, or an outside wall. Run the cable from the antenna to the booster unit inside your home or office, plug it in, and switch it on.
You just need to find the right spot for that outdoor antenna because the stronger the signal it picks up, the better your coverage will be inside.
Most home boosters are easy to set up yourself, but if you’ve got a big office or multi-storey place, you might want a pro to help with extra antennas or tidy up the cabling.
Well, coverage depends on the booster model. Small boosters can handle a flat or a few rooms, typically 300 to 500 square metres. However, larger boosters can cover an entire house, up to 5000 square metres. These models would be super useful for warehouses or multi-storey buildings.
Yes, multi-network boosters can boost one or more users on different networks simultaneously. This is useful when several people in a home or office use different mobile networks. Some people may need a Spark signal booster, other may need 2degrees signal booster and some 1NZ Signal Boosters, if they want to boost only the carrier they're on.
But a multi-network booster makes sure everyone is getting stronger and more reliable coverage while, at the same time, not requiring separate devices for each network.
Yes, as long as they are approved by New Zealand's telecommunication authorities. Legal boosters are designed to enhance your coverage while still being part of a wider network. The use of illegal boosters (not approved by authorities) may not only affect the network, but could also potentially affect emergency services (this is particularly important).
Of course. Using a signal booster can provide faster download and upload speeds by increasing the strength of your mobile signal.
This leads to smoother video calls and less buffering when streaming. A stronger mobile signal also helps your device stay connected without constantly searching for a signal, making your mobile experience more reliable overall.
A mobile signal booster/repeater is a device that enhances mobile signals within your home, workplace, or any property. It works by capturing the outdoor signal from a cell tower, amplifying it, and then broadcasting the stronger signal indoors.
It does not create a signal from thin air; it simply boosts the signal that is already there, helping you stay connected in areas where phone service would otherwise be weak or unreliable.
