i3-Series Intellian Satellite TV Antenna For Marine
Superior Tracking Performance
The Intellian i3 provides superior tracking performance compared to antenna systems of a similar size. With its stylish dome, the i3 is ideal for boats over 8m (25ft). The i3’s high signal gain makes it the best performing 37cm (15in) antenna system available today.

The i3 Highlights
- Built in Wi-Fi enables one touch diagnostic and updates from your PC or iOS device
- Auto satellite switching function from your remote control
- Compatible with leading satellite TV service providers around the world
- 60° per second turn rate ensures signal tracking at high speeds and in rough seas
- Travel further North or South with an extended elevation range of 10° to 80°
- Built in GPS enables faster signal acquisition
- Simplicity of design, no external compass or rate sensors required
- Built-in HD module for Ku-band HD TV reception

Constant and Seamless Entertainment
With innovative technologies, the i3 always maintains the highest signal strength available and ensures crystal-clear TV reception.
Intellian’s super-efficient 37cm (15 inch) diameter antenna provides constant, seamless reception while the vessel is moored, at anchor, motoring along the coast or cruising offshore. The i3 2-axis antenna features a built-in GPS which can accelerate the satellite signal acquisition time while boats with conventional antennas are left watching “SEARCHING FOR SATELLITE” on their screen.
Automatic Satellite Switching
DISH (US) and Bell TV (Canada) users will benefit from using an Intellian MIM (Multi-Satellite Interface Module) . The Intellian MIM is required to facilitate automatic switching between satellites for these services, allowing boaters to enjoy changing channels with automatic satellite switching just like a home system. See the Intellian MIM product guide for further details.
i3 Features
Fully Automated System
- Automatic Satellite Search and Identification Function
- 2-axis Stabilization provides high speed tracking
High Performance Antenna
- 37 cm (15in) diameter parabolic antenna for receiving the Ku-band satellite signals
- Circular or linear polarization depending on region and LNB selected
- Built-in HD module for Ku-band HD TV reception
Intellian’s Patented Quick&Quiet? Technology (iQ²)
- iQ² Technology allows you to tune in quickly, maintain a solid signal lock, and enjoy your favorite TV programming in quiet comfort
- The Wide Range Search (WRS) Algorithm delivers the fastest signal acquisition available anywhere
- Dynamic Beam Tilting (DBT) technology uses intelligent, real-time beam analysis to ensure superior signal quality while eliminating intrusive background noise experienced with conventional antennas
Antenna Control Unit
- Intuitive controls with a digital information display on the ACU
- Wireless automated updates and diagnostics via Aptus PC and Aptus Mobile
- DC Out Port for easy power supply to the Intellian MIM or the Shaw Decoder Module
Multiple Receiver Capability
- Multiple receivers and TVs can be connected using a Multi-Switch or the Intellian MIM (Multi-Satellite Interface Module)
- Using the MIM a master receiver can be selected to control the target satellite
- In North America, when using Dish or Bell TV, a MIM is required, enabling automatic satellite switching from your remote control just like you do at home
Built-in GPS and NMEA 0183 Interface
- The i3 includes a built-in GPS inside the Antenna Unit for faster signal acquisition
- The ship’s GPS can also be connected through the NMEA 0183 port on the rear panel of the ACU
Compact Size
- 43cm (16.9 inch) antenna radome diameter
- Antenna weighs less than 9 kg (19.8 pounds)
Three Year Global Warranty
- Industry leading 3-year parts and workmanship guarantee with a 2-year labor warranty for all antenna systems, ensuring peace of mind with your hardware investment
