Applies a typical regional frequency value.
Typical: 868.42, 908.42, 921.42.
Two-way includes a small reliability penalty.
Higher power may reduce battery life.
Typical range: −120 to −70.
Use 10–16 dB for outdoor gardens.
0 dBi for compact internal antennas.
Directional antennas can boost range.
Short cables: 0–1 dB.
Hedges and trees can add large losses.
Brick sheds and metal gates are costly.
Moist soil, rain, clutter, mounting effects.
Applies suggested losses and factor.
Scales the theoretical distance to a practical one.
Distance you want to cover end-to-end.
Used to suggest repeaters conservatively.

Formula used

This calculator uses a link budget to find the maximum allowable free-space path loss, then solves for distance.

How to use this calculator

  1. Select your region, then apply the suggested frequency.
  2. Pick an environment profile, then apply its garden losses.
  3. Adjust foliage and obstacle losses for your exact layout.
  4. Set fade margin higher for reliability and fewer retries.
  5. Click calculate, then export CSV or PDF for records.

Example data table

Sample garden scenarios for quick comparison.

Values are illustrative and vary by hardware.
Scenario Frequency (MHz) Foliage loss (dB) Obstacle loss (dB) Fade margin (dB) Environment factor
Open beds, clear view 868.42 3 2 10 0.85
Mixed beds and shrubs 868.42 6 4 12 0.70
Dense hedges and trees 908.42 10 5 14 0.55
Near shed and brick wall 868.42 5 8 15 0.50
Practical note: Place repeating nodes higher than foliage, and away from metal.
