Si-Tex T941A 4kw Color Radar with Dome

Improve visibility and situational awareness on the water with the Si-Tex T941A 4kW Color Radar with Dome. This standalone marine radar combines a daylight-viewable 8.4-inch color LCD with a powerful 4kW transmitter and 25-inch radome antenna, providing dependable target detection from close range out to 36 nautical miles.

Si-Tex Hyper-Digital Processing™ technology reduces unwanted noise and clutter, producing clearer radar images and improved separation between nearby targets. Its true-color presentation displays echoes in different colors according to signal strength, helping operators distinguish strong targets, weak returns, land, buoys, and surrounding vessels.

The Dual Range function lets you monitor short- and long-range radar views simultaneously. You can watch a nearby navigation marker while maintaining awareness of vessels or land at greater distances. Selectable antenna speeds of 24 or 48 rpm support efficient long-range scanning and faster updates when tracking close, fast-moving targets. Operation at 48 rpm requires a suitable 24V DC supply.

Automatic tuning maintains radar sensitivity with minimal adjustment, while manual controls remain available for experienced operators. Warning Zone alarms notify the crew when a target enters or leaves a selected guard area. True Trail functionality also helps differentiate moving vessels from stationary objects by showing their direction of movement.

The display accepts a compatible CCD camera input for split-screen radar and video monitoring. RGB output supports up to two optional external monitors. Optional ATA and AIS interfaces can expand tracking and vessel-information capabilities when connected to the required equipment.

With rugged IPX5 display protection, straightforward controls, and professional navigation features, the Si-Tex T941A is suited to fishing boats, cruising vessels, workboats, and commercial marine applications. Product details are supported by the Si-Tex T941A specifications and T941A product listing.
