Raymarine 45STV Marine Satellite TV Antenna (45 cm)

The Raymarine 45STV is a 45 cm marine satellite TV antenna system that offers a great blend of size and performance. It brings the luxury of satellite television to mid-sized vessels roughly in the 10.7–15 m range (35’–50’ length). This antenna is engineered to make sure owners of motor yachts and sailboats in this class can enjoy reliable TV entertainment offshore. With its larger dish compared to the 37STV, the 45STV delivers stronger signal gain and wider coverage, which is ideal for cruising coastal and even offshore waters where signals might be weaker.

Popular Size with Higher Performance: Featuring a 45 cm reflector, the 45STV provides robust reception and nationwide coverage in both North America and Europe, as well as regional satellite services around the globe. This popular mid-size dome is often considered the sweet spot for many boaters – large enough to capture signals for a broad range of channels and regions, yet compact enough to fit on flybridges and radar arches of cruising boats. It’s the perfect balance for boats that require reliable TV at sea without the bulk of the largest domes.

Faster Signal Acquisition: Equipped with Raymarine’s exclusive Wide Range Search (WRS) technology, the 45STV can quickly search for and lock onto satellite signals with remarkable speed and accuracy. When you power on the system or navigate into a new coverage area, the antenna rapidly scans for the target satellite and acquires the signal, minimizing your waiting time. This means you can start watching your TV programming almost immediately after dropping anchor or turning on the unit. WRS dramatically reduces the delay and frustration often associated with finding satellites, ensuring a fast and seamless TV viewing experience as you move.

Stable Tracking on the Move: The 45STV maintains a rock-solid connection to the satellite, even as conditions change, by leveraging Dynamic Beam Tilting (DBT) technology. A high-speed sub-reflector mechanism continuously samples signal strength (up to 50 times per second) and adjusts the antenna’s aim to compensate for the boat’s motion. By intelligently tilting the beam rather than constantly moving the entire dish, the system reduces wear, noise, and power draw while keeping the picture locked in. This means that whether you’re cruising at speed or encountering rough seas, the antenna stays locked onto the satellite for uninterrupted viewing. The reduced need for constant big corrections also extends the product’s life and keeps the operation quieter.

HDTV and Built-in GPS: As a modern satellite TV system, the Raymarine 45STV fully supports high-definition TV content. The antenna’s ACU (Antenna Control Unit) comes with an integrated HD module that seamlessly handles DVB-S2 HDTV broadcasts, so you can enjoy your favorite channels in crystal-clear HD on board. Additionally, the 45STV features a built-in GPS receiver to enhance the antenna’s performance. The GPS data helps the system achieve even faster satellite acquisition and improves positional accuracy for the antenna’s targeting. In effect, the 45STV knows where it is, which aids it in finding the right satellite faster and maintaining lock as your boat moves across the water. This is especially beneficial when cruising along regional boundaries or if you momentarily lose signal – reacquisition is swift and precise.

Easy Installation & User-Friendly Operation: Raymarine designed the 45STV for straightforward installation and integration. The antenna connects to its control unit with a single coax cable, carrying power, data, and the TV signal all-in-one. Fewer cables mean a quicker, cleaner install and less chance of something coming loose. Once installed, setup is minimal – the advanced Evolution ACU requires little to no manual calibration, as it automatically adjusts to optimal settings. Operating the system is very user-friendly: the included Antenna Control Unit features a clear digital display and simple controls, allowing you to manually select satellites or run diagnostics easily. The 45STV also supports wireless connectivity; with built-in Wi-Fi, you can link the ACU to a smartphone, tablet, or laptop using the Raymarine Aptus app for remote control and firmware updates. This means you can perform system checks or update the antenna’s software without having to access the unit physically – a great convenience when you’re out at sea.

Multi-Receiver Support: The 45STV is equipped with a high-efficiency parabolic dish and LNB that support dual or quad outputs. This capability allows you to hook up multiple satellite receivers or televisions on the boat (for example, one in the salon and one in a cabin) to the same antenna. Everyone on board can watch different channels simultaneously, all fed by the single 45STV dome. The system’s advanced design also features automatic satellite identification (with a high-speed DVB-S2 decoder) to lock onto broadcasts quickly, and a next-generation ACU that offers intuitive controls plus a NMEA 0183 interface for connecting the vessel’s own GPS if needed. Backed by Raymarine’s global service network and a multi-year warranty, the 45STV provides peace of mind along with its top-tier performance, ensuring you get great value and longevity from your marine satellite TV investment.
