Research-based: we haven't tested these mowers. How picks are chosen

We'd pick the navigation your yard can actually feed. Heavy tree cover points to a mower that can map with LiDAR, not to RTK alone. An open acre with steep banks can use network RTK if your lawn has Wi-Fi or cell service. Here's the thing: vision on these models is an extra pair of cameras, not a fourth setup you'd buy by itself.

Two checked examples

For heavy trees, we'd look at the LUBA 3 AWD 3000, rated 0.75 acres (32,670 sq ft) and using LiDAR, Network RTK, Vision. For an open steep acre, the Navimow X430 is the one we'd look at, rated 1 acre and 84% (40°), with Network RTK, Vision, Time-of-flight sensor.

Four setups, one yard

Boundary wire

A wire is buried or pegged around your lawn, and the mower follows it. It doesn't need sky. It fails when the wire is cut, or when a bed moves and nobody moves the wire. On the ladder, the Worx Landroid M WR147 is a boundary-wire model rated 0.25 acres. The Husqvarna Automower 420 iQ can run wire-free or with a boundary wire.

Antenna RTK

A reference antenna on your property sends corrections. It needs open sky above the antenna, and the mower still needs sky along its path. Trees, walls, and the roof edge weaken it. Raising only the antenna doesn't fix canopy over your grass.

Husqvarna's own EPOS guidance asks for a reference station at least 6.5 ft (2 m) high, with at least 135° of open sky. That's Husqvarna's rule for its station, published Jan 28, 2026. It isn't a universal spec for every brand. Husqvarna reference-station guidance.

Network RTK

Corrections arrive over Wi-Fi or cell service, so there may be no antenna to mount. The Navimow X430 includes an antenna and says it's optional. The Navimow i210 AWD is network RTK plus vision and doesn't use an antenna. The fix weakens when cell service is poor at your lawn, or when canopy covers the path. A yearly fee after a free period is a separate question, answered on each review from that maker's page.

LiDAR or a camera

The mower builds a map from what it sees, so nothing has to be installed in your yard. It weakens when the camera reads leaves, weeds, or bare soil as "not grass," and when a LiDAR unit pauses in heat. The Dreame A3 AWD Pro 2500 is LiDAR plus vision, with no RTK and no wire, rated 0.62 acres. The LUBA 3 AWD 1500 is LiDAR plus vision only. The 3000 adds network RTK. The 1500 is rated 0.37 acres.

The Worx Landroid Vision Cloud WR340 uses cloud RTK, with no antenna, plus stereo vision, and Worx says a V-SLAM fallback takes over in shade. It's rated 1 acre and 30%.

Makers usually publish one maximum slope and don't say whether it applies in the middle of your lawn or at the edge. When a model also gives a lower figure for the edge, that's the one to use there. If your bank runs into a bed or a fence, we'd leave some margin, because edges are usually harder.

What this means when you choose

Open quarter acre and you don't want an antenna: we'd pick the Navimow i210 AWD.
Trees, and you don't want a base station: we'd pick the Dreame A3 AWD Pro 2500 or the LUBA 3 AWD 3000.
Open acre, steep banks, Wi-Fi or cell at the lawn: we'd pick the Navimow X430.
Open acre, gentler slopes, cloud RTK: we'd pick the Worx WR340.

Questions

Do I need an antenna in the yard?

Only if you're on antenna RTK. Network RTK uses Wi-Fi or cell. The X430 includes an antenna and describes it as optional. The i210 page says no antenna. LiDAR models such as the Dreame 2500 don't use RTK at all.

Will trees block RTK?

They can. The mower needs a fix along its path, not only at the antenna or the dock. If canopy covers your grass, that's the failure, which is why we'd compare a LiDAR model when the lawn is wooded.

Is a boundary wire still reasonable?

Yes, if you want a mower that doesn't depend on sky. The trade is the install, and a wire that can be cut. The ladder marks boundary-wire models with a dashed line.
