NASA - H-Vector navtex antenna

Conventional navtex antennas respond to the connected to the electrical component navtex radio signal. This usually works at sea, where electrical noise is low, very good, but in the port and near the shore, the signal is often suppressed by interference.In most pleasure boats, the electrical system acts as an effective ground for the antenna, but it can also be a source of interference be caused by other electrical equipment on board. Electrical noise may cause a bad reception. Especially in marinas where noise sources can interfere with the reception in the area or at sea, if poorly unsuppressed electrical appliances are in use.The omnidirectional antenna H-vector is not sensitive to electric fields, but receives the magnetic component of the navtex signal. As a result, it is less sensitive to locally generated interference, whether in port or at sea.The result is that, under unfavorable conditions, the H-vector antenna a significant improvement in navtex reception can deliver. The mushroom-shaped antenna is compatible with the Clipper navtex, target navtex series 2 and the Easy navtex.The antenna can (1 "/ 14TPI, not included) with a standard antenna on the cabin roof or the tail basket to be mounted.Suitable for all NAVTEX receiver NASA MARINE with two receiving frequencies:- Target Navtex Pro Plus from model year 2002- Clipper Navtex (Dual Channel Receiver)- PC Navtex Pro 2- Easy navtex- connecting cable, length 7 m- Suitable for mounting on antenna feet with 1 "/ 14 T.P.I. standard thread
