Adjustable Antenna Mount Base

Key Features

• 180° Full Swivel Rotation – Rotate the antenna threaded socket to any horizontal angle for optimal signal reception
• 45° Locking Handle – Press the handle down 45° to lock the antenna firmly in place; lift to release and reposition instantly
• Hard Nylon Construction – Rigid, UV-stabilized nylon body resists cracking, fading, and corrosion in saltwater and outdoor environments
• Stainless Steel Pivot Bolt – Corrosion-resistant pivot hardware ensures smooth rotation and long-term durability
• Standard Threaded Socket – 2.5cm threaded antenna port fits most standard marine and RV antenna bases
• 4-Hole Flat Base Plate – Secure flush-mount installation on any flat surface; 9.2×6.5cm footprint
• Wide Application – Boats, yachts, RVs, caravans, trucks — anywhere you need a repositionable antenna mount

Solves These Common Problems

• Fixed mounts that can’t be repositioned without re-drilling
• Antenna drift and vibration loosening the mount underway
• Weak signal from a non-optimal antenna angle
• Corroded or cracked plastic mounts after one season of sun and salt exposure
