Nasa Marine Easy Navtex Complete With H Vector Antenna



Nasa Marine Easy Navtex Complete With H Vector Antenna

Ref: SM523-EASY-NAV-HV

Description

Easy to read. This new Navtex receiver features big, bold characters and intuitive message formatting.

The omnidirectional H-Vector antenna is not sensitive to electric fields but to the magnetic component of the navtex signal. As a result it is less sensitive to locally generated interference and, as it does not need a ground, it is not affected by conducted ground interference whether in harbour or at sea.

Easy to program. Simple menus let you select which stations and which message categories you want to receive.
Easy on your battery. Its low power consumption and power saver mode on the backlight ensure minimum current drain.
Easy channel switching. Programmable automatic switching between the 518Khz and 490Khz channels. No more getting up early to switch channels.
Easy signal analysis. The built in spectrum analyser shows the signal in real time whilst you are receiving messages.
Easy Navtex is designed for panel mounting and is supplied with antenna, power cable and dust cover.

Conventional navtex antennas respond to the electrical component associated with the navtex radio signal. They usually perform well at sea where electrical interference is low but can sometimes be overwhelmed with interference especially when in harbour and connected to shore power.

In most small craft the electrical system acts as an effective ground for the antenna but it can also be a source of interference conducted from other electrical equipment on board. Electrical interference can result in poor reception especially in a marina where the ambient level is high or at sea when poorly suppressed electrical equipment is in use.

The omnidirectional H-Vector antenna is not sensitive to electric fields but to the magnetic component of the navtex signal. As a result it is less sensitive to locally generated interference and, as it does not need a ground, it is not affected by conducted ground interference whether in harbour or at sea.

The net result is that, under adverse conditions, the H-Vector antenna can deliver a significant improvement to navtex reception. The mushroom shaped antenna is compatible with the Clipper navtex, series 2 Target navtex and with the navtex engine. It can be mounted on a cabin roof or rail mounted using an appropriate threaded antenna base.

Note - the antenna mount is not included
