Covers 165 sq ft required materials.
Estimated essential tools & safety gear.
Baseline DIY execution cost estimate.
Estimate whether your station can reliably access the repeater.
Include feedline loss when comparing antenna setups.
Convert dB loss to power fraction for link planning.
Baseline path loss to repeater site before terrain factors.
Confirm offset direction matches band plan.
Common input/output spacing by band.
| Band | Offset | Tone |
|---|---|---|
| 2 m | ±600 kHz | Often 100.0–114.8 Hz |
| 70 cm | ±5 MHz | Check local band plan |
| 1.25 m | −1.6 MHz | Less common |
Monitor 30 seconds before transmitting — avoids doubling and colliding with nets.
A ¼-wave on the roof beats any rubber duck inside the car.
Some repeaters route to wide-area nets — know when your signal goes beyond local coverage.
Crucial code requirements, material risk alerts, and prevention checklists for Repeater Operation Guide.
⚠️ Risk Warning: Purchasing net calculated material causes project delays when cuts or breakage occur.
💡 Prevention Action: Always add a 10%-15% buffer allowance to initial calculated quantities.
⚠️ Risk Warning: Applying finishes to dusty or uneven surfaces reduces adhesion by up to 60%.
💡 Prevention Action: Vacuum, prime, and check levelness (max 1/8" gap over 10 ft) before starting.
