Magnet base or roof-side mount? K3000 vs K311
How the Diamond K3000 magnet base and the K311 roof-side mount differ, and which suits your vehicle.
A mobile antenna needs a mount that holds it firmly. Diamond makes two very different options.
Diamond K3000 — tri-magnet base
- Three magnets of about 8.5 cm on a tilt structure
- Holds antennas up to 1.85 m and 1.1 kg
- Size about 23.5 × 23.5 × 4 cm, weight about 1.8 kg
- For iron surfaces only; the manufacturer specifies driving under 100 km/h
- Cable set sold separately (for example Diamond RG3MR / RG6MR)
No drilling and no clamps: place it on a steel roof and it is ready. Good for longer antennas and for moving the antenna between vehicles.
Diamond K311 — roof-side mount
- Fold-down mount for the roof side (rain gutter)
- Two-axis angle adjustment
- Three screw types included for different gutter widths
- Body about 75 × 45 mm; coax cable and antenna not included
A compact, fixed installation that stays on the vehicle. Pair it with a cable set such as the Diamond 2D3MR or 5D7MR.
Which one?
Choose the K3000 for a no-tools installation or a larger antenna on a steel roof. Choose the K311 for a permanent, compact fitting on the roof edge.
