AI Technical Summary
Tactical antennas for the 145 MHz band are cumbersome to hold and require dedicated mounting bases, prone to bending, and are not easily adaptable to various environments.
A tactical antenna is suspended from a structure using a hook, suction cup, or magnet, connected via a communication cable to a transceiver, allowing easy handling and stable communication without increasing the transceiver's weight.
The suspended configuration facilitates easy handling and stable communication with reduced bulk, maintaining performance without adding weight to the transceiver.

Abstract
Description
Technical Field
[0001] The present invention relates to a tactical antenna that can be suspended.
Background Art
[0002] Although a tactical antenna can be compactly stored, when it is directly attached to a handheld transceiver (Non-Patent Document 1), an antenna suitable for transmission and reception in the 145 MHz band has a length of 1 m. Holding these antennas for a long time is difficult because they are large and heavy. Even when separating only the antenna and installing it in a place where transmission and reception are easy, there are problems such as the need to install a dedicated pedestal and the antenna itself being bent.
[0003] A horizontally long TV antenna attached to the sun visor of the front window of an automobile (Patent Document 1) fits the shape because the sun visor is horizontally long. However, since a tactical antenna is used vertically with respect to the ground (Non-Patent Document 1), it cannot be attached horizontally to the sun visor.

Summary of the Invention
Problems to be Solved by the Invention
[0006] While tactical antennas can be stored compactly, when attached directly to a handheld transceiver, those suitable for 145MHz band transmission and reception can be as long as 1 meter. Holding these for extended periods is cumbersome due to their size and weight. Furthermore, separating the antenna and placing it in a location convenient for transmission and reception requires a dedicated mounting base, and there are issues with the antenna itself bending or breaking. [Means for solving the problem]
[0007] A tactical antenna (2) is suspended from a structure by attaching a fixing device (1) made of a hook, suction cup, or magnet to the tactical antenna (2). A transceiver (4) is connected to the tactical antenna (2) via a communication cable (3), resulting in a suspended tactical antenna that does not increase the weight of the transceiver (4) and is easy to hold and transmit / receive by hand. (Figure 1) [Effects of the Invention]
[0008] A fixing device (1) made of a hook, suction cup, or magnet is attached to a tactical antenna (2) and suspended from a structure. A transceiver (4) is connected to the tactical antenna (2) via a communication cable (3). This allows for simple, inexpensive, and stable communication using a suspended tactical antenna that does not increase the weight of the transceiver (4) and is easy to hold and transmit / receive without burden. All of these devices are not bulky when carried. [Brief explanation of the drawing]
[0009] [Figure 1] This is a conceptual diagram of a suspended tactical antenna. [Modes for carrying out the invention]
[0010] A tactical antenna (2) is suspended from a structure by attaching a fixing device (1) made of a hook, suction cup, or magnet to the tactical antenna (2). A transceiver (4) is connected to the tactical antenna (2) via a communication cable (3), resulting in a suspended tactical antenna that does not increase the weight of the transceiver (4) and is easy to hold and transmit / receive by hand. (Figure 1) [Examples]
[0011] A fixing device (1) made from an S-shaped hook (8mm diameter, 115mm length, 50mm width, made of resin) and vinyl string was attached to a tactical antenna (Foldable Tactical 01, 108cm total length) (2) and suspended from a structure (support for the rain gutter on the eaves of the second floor). Using a communication cable (RG58 50ohm, 200cm x 2) (3), and with the window closed, it was connected to an indoor transceiver (Yaesu Musen Co., Ltd. FM 144 / 430MHz DUAL BAND TRANCEIVER FT-65) (4) via a wind-through cable (RF coaxial cable, 40cm), allowing communication and conversation with an amateur radio operator 53.3km away on frequency 432.88MHz. (Figure 1) [Industrial applicability]
[0012] This invention can be manufactured using commercially available hook, suction cup, and magnet-based fastener manufacturing techniques, and can be combined with tactical antennas as an option, making it possible for fastener and antenna manufacturers to mass-produce it. While the usefulness of transceiver communication, as opposed to the internet or telephone lines, has been demonstrated during large-scale natural disasters such as major earthquakes, it is difficult to carry large fixed equipment or stationary antennas when actually evacuating, making portable handheld transceivers a viable option. However, the output of many portable handheld transceivers used in amateur radio is limited to a maximum of 5W, which is insufficient considering the transmission and reception distance of radio waves. In such cases, the performance of the antenna is naturally expected to be important, and tactical antennas are available that offer good gain and a reasonable communication distance, including 1-meter-long half-wavelength antennas for 145MHz. By setting up a tactical antenna at an appropriate angle in a location with a clear line of sight at the evacuation site, it is possible to wait for CQ responses and monitor for usable radio waves in a stable environment similar to that of a fixed equipment station.

Claims
[Claim 1] A tactical antenna (2) is suspended from a structure by attaching a fixing device (1) made of a hook, suction cup, or magnet to the tactical antenna (2). A transceiver (4) is connected to the tactical antenna (2) via a communication cable (3), allowing for a suspended tactical antenna that does not increase the weight of the transceiver (4) and is easy to hold and transmit / receive by hand.
