Description

Antenna for receiving a television signal for outdoor, indoor and for vessels as well as method of receiving a television signal automatically}

The present invention relates to an indoor and outdoor combined TV receiving antenna, a ship TV receiving antenna using the same, and a ship TV receiving method using the TV receiving antenna.

It is needless to say that in a TV receiver installed on a ship sailing at sea, the desire to see the screen of the TV receiver visually during navigation is powerful and not only a desire to appreciate the screen but also important for safety navigation.

Conventionally, a TV receiver mounted on a ship is known to be able to obtain the best image only when the ship is stopped and it is very difficult to watch the best image with the TV receiver during navigation. It is considered that there is a difficulty.

That is, firstly, since the angle of the transmission station and the antenna installed in the vessel is changed due to the change of the course of the ship navigation, it is necessary to operate the rotator to adjust the angle, and the operation corresponding to the change of the course is sufficient. I can't speak. Secondly, it was difficult to obtain a clear image at sea, except by means of satellite communication, in general, which can only receive surface waves spreading over the surface of the sea, and is also susceptible to reflections from various directions. . Third, since the transmission channel of a satellite station changes frequently in ships traveling along the coast, it is necessary to set the TV receiving antenna in that direction each time. In general, with respect to the VHF wave, the composite output with the surface reflection wave cannot be obtained only in the shallow place within 50m depth, and the reach distance is not long compared to the land, and in the UHF wave at the position close to the land, The state of the image is unstable due to the reflected wave of. Fourth, it is difficult to respond due to the fluctuations in the direction of the wave, the intensity of the wave, and the spreading path due to the influence of blue light in the course of the ship's navigation, as well as TV having projections from the hull in the harsh environment of heavy rain and snow Receiving antennas are fragile and short in life, which makes them very difficult to provide for practical use.

Conventionally, as is widely known, the VHF and UHF of a ship is used as a receiving system for TV broadcasting, and the VHF and UHF are rotated by a common pole, respectively, by a multi-element arrayed beam antenna (hereinafter referred to). TV receiver antennas have been used in which the outputs of VHF and UHF, which install and receive rotator means, are mixed by a mixer, and the output current is induced to the TV receiver through a superposition type amplification means via a cable.

However, for example, in the conventional method using the Yagi antenna of each of the VHF and UHF, the direction of the antenna is moved by rotating by using a rotator means that rotates with a common pole from the antenna element of the projection member. It is necessary to constantly readjust it according to the direction. On land, it is also possible to hold and fix the direction of the transmitting station and the antenna under the best conditions. However, on the sea, due to the propagation of radio waves, the surface wave reflecting wave is strongly influenced, and there are many reception obstacles. Due to the surrounding waves, the direction, path, polarization characteristic and electric field intensity of the wave are disturbed, and the Yagi antenna, which uses only electric field waves mainly in the radio energy, has a drawback that can only be used in principle. In other words, the directivity is too sharp to cope with fluctuations in direction, and only a single polarization characteristic can be coped with, so that illusions are likely to occur on the screen due to side lobes and polarization mismatches, and the gain is not stabilized. In the process of navigation, it is very difficult to obtain a viewable view. The Yagi antenna, which mainly uses electric wave energy energy, has a high operating gain near the center frequency and sufficient directivity, but it is difficult to use the radio wave away from the center frequency. When applied to a moving object such as a ship requiring synthesis and sailing, it is extremely difficult to cope with radio waves coming out of the effective angle range.

The present invention basically eliminates the shortcomings of conventional onboard TV receiving antennas and enables the normal reception of TV reception in coastal navigation of a ship. Can respond to changes. To provide a clear image reception of the TV and to withstand harsh natural conditions and to provide a ship-mounted TV receiving antenna with less trouble.
