    Relay box with a horizontal antenna on a vertical wall.
    This invention relates to the mounting of an antenna for radio communication on a vertical wall of, for example, a relay box arranged next to a railroad. Other railway applications are also conceivable, for train, tram or metro, for passenger and freight transport, preferably with an overhead line above the railroad for the electrical supply of the train locomotive. In particular, the side of the wall on which the antenna is located is an outside, so is located in the open air and is exposed to weather influences.
    As a rule, the relay box contains a large number of galvanic relays from, for example, a railway protection system. For example of the type of protection relay (so-called Bl relay). The relay box is, for example, part of a railway application aimed at the control and control of points or level crossings, or for track occupancy reporting. The relay box contains, for example, one or more of an override relay, voltage monitoring relay, control relay, control relay, track repeat relay (TPR) or track relay (the TR or the so-called B2-Vane relay is a widely used track relay, the track relay indicates whether a train is located in the section concerned).
    The antenna is part of a radio communication system, for example for receiving or transmitting a signal for calling a service engineer or making a change in the train control to make the track in question inaccessible to train traffic or to impose a speed limitation. A transmitting and / or receiving unit is connected to the antenna, which, for example, forms part of a data processing unit. The radio communication system is generally included in the housing, such as a relay box, of which a wall carries the antenna. The radio communication system is, for example, adapted for data communication with any, or all, of the relays in the relay box to, for example, read out relay positions, or associated data, and send them wirelessly to a remote location via the antenna. The antenna is, for example, adapted for GSM or UMTS or LTE or LPWAN or equivalent transmission frequencies.
    It is known from practice to equip a relay box on one of its vertical outer walls on the outside with a blind plate lying flat against the wall on which a flat lying, vertically positioned antenna is mounted. The blind plate is a flat metal plate with flat surfaces and a thickness of 1.5 millimeters.
    The object of the invention is to improve the operation of the communication system and at the same time to increase user-friendliness.
    To this end, it is proposed to mount the antenna at an angle with respect to the vertical and / or side of the associated upright, preferably substantially vertical wall, preferably at an angle of more than 25 or 45 or 70 and / or maximum 130 degrees, with the vertical, more preferably substantially horizontal. Preferably further to the side of the wall than the thickness of the known mounting on the blind plate, more preferably at a distance of at least 5 or 10 millimeters.
    The antenna is preferably mounted on the wall by means of an antenna holder, preferably other than a blind plate, possibly with the intervention of a blind plate. The antenna holder is preferably arranged, for instance equipped with a recess or housing or receiving part or inner space, for containing a length piece of the antenna cable, for example a piece of excess length which is stored in the assembled form, for example rolled up, in the antenna holder.
    Preferably one or more of the following applies: the antenna is at a minimum of 50 centimeters and / or a maximum of 1 or 1.5 meters above the local ground level or the ballast bed of the railway; the antenna is at a minimum of 0.25% and / or a maximum of 50% or 75% or 90% of the height of the associated wall; the wall is flat and / or rectangular; the antenna is a spiral antenna; the antenna is mounted on the top of the holder, preferably protruding above the top of the antenna holder and / or above the top of the antenna holder; the wall is of an upright type, preferably substantially vertical; the antenna and / or holder is in the outside air and / or is / are mounted on the side of the wall facing the outside air; the wall is of stony material or metal, such as sheet metal, for example steel or aluminum; the antenna and / or holder forms a protrusion of the wall.
    For the antenna holder, preferably one or more of the following applies: has a base, preferably plate-shaped and / or flat, for placement against the wall and an angle, preferably a minimum of 25 or 60 or 80 degrees and / or a maximum of 100 or 120 degrees, such as substantially 90 degrees, including carrier of the antenna, preferably plate-shaped and / or substantially flat; the carrier and the base connect with each other with a first edge; a sealing surface, preferably plate-shaped and / or substantially flat, connects with one edge to a second edge of the carrier and with another edge to a second edge of the base; the one and the other edge of the sealing surface face each other; the sealing surface makes an angle of less than 90 or 70 degrees with the support and / or the base, for example about 45 degrees or between 30 and 60 degrees; side faces that face each other and / or with one or more of the base, support, and sealing face therebetween; the side faces connect with a respective edge to a third edge of one or more of the base, sealing face and carrier; a side surface is substantially triangular, preferably of rectangular type; one or more of the base, support, sealing surface and side surface (s) is airtight and possibly connect to each other airtight; is watertight for precipitation, possibly if properly mounted on the wall, at least at the top, preferably on all sides; has a set of walls which connect to each other so that a space bounded on all sides to the environment is formed, possibly with the exception of an access opening in one of the walls which is preferably associated with closing provisions; the access opening is in the base facing the wall and / or is covered by the wall; the access opening is adjacent to an access opening in the wall so that the spaces in the holder and behind the wall are connected to each other via these access openings while these openings do not provide access from outside; the surround of the antenna holder completely around the access opening connects sealingly to the wall in the properly mounted condition; one or more of the base, support, sealing surface, side surface (s) contains a kinked part, preferably edge area and / or has a rectangular shape.
    In the following, the invention is explained in a non-limiting manner with reference to the accompanying drawing.
    FIG. 1-4 show in perspective resp. top view, head view and side view a relay box with antenna according to the invention;
    FIG. 5-8 show in perspective resp. top, front and side view the holder with antenna on it according to Figs. 1-4;
    FIG. 9-11 show a top resp. side and rear view of the antenna holder of fig. 5-8.
    Dimensions in the drawing are in millimeters.
    Fig. 3 shows that the antenna holder 1 is mounted slightly below half the height on the relay box 3.
    FIG. 5 provides a view of the space inside the antenna holder, via the permanent opening 5 in the base 8. With the antenna holder mounted, the base faces the associated wall 4 and the enclosure connects sealingly to the space inside the antenna holder completely around the access opening to the space inside the antenna holder. relay box wall. Four mounting pins protrude from the base.
    The drawing shows that the side faces 9 are substantially rectangular triangles and the other faces 6, 7, 8 are rectangles. The plane that the antenna 2 carries is horizontal if properly installed and then the antenna protrudes above the antenna holder.
    The antenna connection wire (not shown) runs from the antenna through the space inside the holder, then through the associated wall and then through the space inside the relay box and connects to the radio communication system in the latter space.
    Alternatives also belong to the invention, for example obtained by an individual measure disclosed above or below, optionally in combination with one or more other individual measures disclosed above or below.
