Umístění GNSS antény

Sky-view check

GNSS receivers require at least 10° above the horizon clear of obstacles to maintain a consistent lock — the more satellites visible, the more robust the setup.

• 360° all-round view is ideal
• No towers, chimneys or trees on a direct line into the GNSS bandwidth
• Urban canyons (narrow streets between tall buildings): plan for multi-GNSS instead of GPS only

Cable route and length

• Under 30 m: a passive antenna is sufficient
• 30-60 m: active antenna or inline amplifier
• >60 m: signal amplifier mandatory — request specification
• Cable type: RG-58/U for short runs, RG-213/U for long runs, shielded in EMC environments

Lightning protection

• Gas-discharge arrestor mandatory on the antenna mast
• Earthing according to local standard (IEC 62305 in Europe)
• Insurance perspective: a 50€ arrestor prevents 2000€ of damage

Mounting

• Magnetic mount: quick but not suitable for permanent installations
• Bolt-mounted: standard for roof placement
• Wall arm: for balconies or walls, sky-view may be limited

EMC and interference

• Avoid transmitters within 50 m (GSM mast, radar)
• Avoid high-voltage cables (they induce noise)
• Test first with a handheld GPS meter before permanent installation
