Building a Safe Station
Setting Up Your Station Safely
Whether you're putting together a home shack or a portable setup, safety should be designed in from the start — not bolted on later.
Shack Layout
- Keep high-voltage equipment enclosed — amplifier cabinets should have covers in place during operation
- Ensure adequate ventilation — 400W amplifiers generate significant heat. Don't put them in closed cabinets without airflow
- Have a master power switch near the operating position that can cut all power to the station quickly
- No food or drinks near equipment — spilled liquid on electronics can be dangerous and damaging
- Fire extinguisher — have a CO2 or dry powder extinguisher rated for electrical fires (Class E/BE) within reach
Grounding Your Station
Good grounding serves three purposes: safety, lightning protection, and RF noise reduction.
- Safety ground: All equipment cases connected to mains earth via the power plug. This is your primary shock protection — if a fault puts voltage on the case, the earth path should trip the breaker.
- RF ground: A low-impedance path to earth for RF. Helps with antenna system performance and reduces RF in the shack. Short, heavy copper strap works best.
- Lightning ground: Heavy conductors bonded to earth rods at the building entry point. All feedlines grounded here.
Single-point ground reminder: All three ground types should connect to a single common point. Having multiple ground paths at different potentials creates dangerous ground loops during a lightning strike and can cause equipment damage.
Portable Operation Safety
Portable operation (field days, SOTA, POTA) brings its own hazards:
- Temporary antennas: Make sure no one can touch antenna wires during transmission. Mark them clearly.
- Generators: Keep them outdoors (carbon monoxide kills). Use an RCD/safety switch.
- Batteries: LiPo batteries can catch fire if damaged or short-circuited. Use proper cases and never leave charging unattended.
- Weather awareness: Pack up if lightning threatens — your portable mast is likely the tallest object around.
- Sun and heat: In Australian conditions, stay hydrated and use sun protection. Heatstroke can impair judgement.
EMR Compliance Documentation
For your home station, you should document:
- Antenna type, gain, and height
- Maximum power you'll use on each band
- Calculated power densities at accessible locations
- Comparison to ARPANSA RPS3 limits
- Any mitigation measures (restricted access areas, reduced power, etc.)
Keep this documentation on file. If there's ever a complaint or inquiry, you can demonstrate compliance.
Summary — The Non-Negotiable Safety Rules:
- Never work on energised equipment
- Always discharge high-voltage capacitors before touching anything
- Never climb a tower alone or without safety equipment
- Disconnect antennas during lightning storms
- Keep people away from antennas during transmission
- Know where your master power switch is
- Have a fire extinguisher in the shack
