Choosing a Repeater Location

Placement determines performance. A well-placed repeater with modest hardware will consistently outperform a poorly placed repeater with expensive equipment.

The primacy of line-of-sight

LoRa signals travel best when there is a clear, unobstructed path between transmitter and receiver. Any obstruction — a building, a ridge, a dense stand of trees — attenuates the signal. The higher your repeater, the more of the surrounding terrain is in line-of-sight.

Location types

Hilltops and ridgelines

The best possible placement. A repeater on a hilltop with 360-degree unobstructed views can serve an area many times larger than the same hardware at ground level. Even a modest elevation gain of 50–100 feet above the surrounding terrain makes a measurable difference.

Rooftops

The most practical option for urban deployments. The highest accessible rooftop in a neighborhood, with the antenna mounted on a short mast, gives excellent urban coverage. Flat commercial rooftops are ideal.

Towers and elevated structures

Communications towers, water towers, and fire lookout towers are excellent platforms. Many communities with amateur radio infrastructure already have tower access — connecting with local ham radio clubs is a good path to shared hosting arrangements.

Mast installations

A 15–30 foot mast in a yard or field dramatically improves line-of-sight over the surrounding area. Particularly effective in flat terrain where even modest height above obstructions makes a large difference.

Common placement mistakes

• Hop gobbling: A poorly placed repeater that is only marginally better than other nodes can consume hop budget without meaningfully extending range. Every hop used by a marginal relay is a hop unavailable for a more distant leg. Place repeaters where they add significant coverage, not just incremental reach.
• Too many repeaters too close together: Dense clusters of repeaters can flood the network with redundant retransmissions. Space repeaters to provide overlapping but not excessively redundant coverage.
• Ignoring the coverage below: Very high-gain antennas on tall structures can create dead zones directly beneath them. Size antenna gain to match your deployment height.

Coverage planning tools

• Meshtastic Site Planner — estimates theoretical coverage from a given location
• HeyWhatsThat — radio horizon visualization based on terrain elevation
• meshmap.net — community map showing existing Meshtastic nodes near you

Always validate coverage estimates with real-world testing — planning tools do not account for buildings, vegetation, or local RF environment.
