Description

The invention relates to ultra-shortwave transmitters using a cathode lamp, whose grid or anode is shorted by wire.

According to the invention, the antenna, which can simultaneously serve as a lead wire, is connected directly to the wire that short circuits the grid or anode.

In FIG. 1 and 2 schematically depict the proposed transmitter; FIG. 3, 4, and 7-modifying it in FIG. one; FIG. 5 shows the transmitters of FIG. 3, 4 in spatial projection; FIG. 8, 9 is one of the embodiments of the transmitter in two projections.

A loop d, a length V4X, VzX, / D, etc., where X is the wavelength, is connected to the loop b, b, which closes the grid c (Fig. 1) or the anode a (Fig. 2).

This conductor serves as a radiating antenna and can simultaneously serve as a wire that supplies a constant voltage to the grid.

It is also proposed to place several electrode systems (Figs. 3, 4.5) in one cylinder, with the spiral grids., C or anodes a, c, which serve as an ultra high frequency oscillating circuit, interconnected by a common jumper b.

The common jumper is connected

one or two antennas. Nodes of all lamps can be welded to each

friend ..

The transmitter can be modified in such a way that the ends 6, the grids c (fig. B) or the anode a (fig. 7) exit outside the bulb of the lamp.

Two conductors d, d of length X / 4 or X / 2 each (X-wavelength) are attached to these ends. These conductors serve as a radiating antenna.

A constant voltage is applied to the grid or anode in the middle.

A form of transmitter (Fig. 8, 9) is also proposed, in which a radiating vibrator d, d attached to an oscillating circuit and is placed inside the cylinder e of the lamp.

The subject matter of the invention.
