coils positioned in a stationary position in proximity of the first housing portion and distant from the second housing portion; a ferrite rod moveable along the central axis within the first and second housing portions; and a ferrite moving and adjusting mechanism for moving and adjusting a position the ferrite rod within the first and second housing portions for tuning a radio communication frequency based on a position of the ferrite rod within the first and second housing portions. ## Claims ### Claim 1 An antenna coupler device, comprising: a housing comprising a first housing portion and a second housing portion, the housing extending from a housing first end to a housing second end along a central axis, defining a chamber; coils positioned in a stationary position in proximity of the first housing portion and distant from the second housing portion; a ferrite rod moveable along the central axis within the first and second housing portions; and a ferrite moving and adjusting mechanism for moving and adjusting a position the ferrite rod within the first and second housing portions for tuning a frequency based on a position of the ferrite rod within the first and second housing portions. ### Claim 2 (depends on 1) The antenna coupler device of claim 1, wherein the ferrite moving and adjusting mechanism comprises a spiral structure defining threads positioned at the second housing portion, wherein the ferrite rod is mounted to the spiral structure in such a manner that a rotation of the second housing portion enables movement of the ferrite rod along the threads of the spiral structure and adjustment of a position of the ferrite rod along the central axis within the first and second housing portions for tuning a radio communication frequency. ### Claim 3 (depends on 2) The antenna coupler device of claim 2, wherein the second housing portion has an internal surface defining an internal wall of the second housing portion, and wherein the spiral structure is affixed to the internal wall of the second housing portion, and wherein the ferrite rod has leg members engaging and moving along the threads of the spiral structure for enabling the movement of the ferrite rod. ### Claim 4 (depends on 3) The antenna coupler device of claim 3, wherein the housing and the spiral structure is made of a non-conductive material. ### Claim 5 (depends on 1) The antenna coupler device of claim 1, wherein the first housing portion has a first housing portion first and second ends and an external surface defining an external wall of the first housing portion wherein the coils are winded around the external surface along the central axis between the first housing first and second ends. ### Claim 6 (depends on 1) The antenna coupler device of claim 1, wherein the coils are copper windings. ### Claim 7 (depends on 1) The antenna coupler device of claim 1, wherein the housing has a cylindrical shape, and the second housing rotates with respect to the first housing portion. ### Claim 8 (depends on 1) The antenna coupler device of claim 1, wherein movement of the ferrite rod inside the first housing portion in direction of the first housing portion first end enables to tune low frequency values and movement of the ferrite rod outside the first housing portion and away of the first housing portion first end enables to tune high frequency values. ### Claim 9 (depends on 1) The antenna coupler device of claim 1, wherein the first housing portion has a first length along the central axis, the second housing portion has a second length along the central axis, and the ferrite rod has a third length along the central axis, wherein the third length is equal or smaller to the first length and second length such that the ferrite rod is entirely positioned within the first housing portion or the second housing portion during frequency tuning. ### Claim 10 (depends on 1) The antenna coupler device of claim 1, wherein the ferrite rod comprises two or more ferrite rods coupled to supporting members for forming a unified structure with the two or more ferrite rods for providing solidity thereto. ### Claim 11 (depends on 1) The antenna coupler device of claim 1, wherein the antenna coupler device is immune to particles and impurities present in a sand desert or other hostile environments such that penetration of the particles and impurities to the coils does not affect operation of the device. ### Claim 12 (depends on 1) The antenna coupler device of claim 1, wherein the coils are exclusively positioned at or in proximity of the first housing portion, and wherein the second housing portion is free of and does not have any coils present therein, winded thereto or in proximity thereof such that high frequency values are achieved when the ferrite rod is entirely positioned within the second housing portion. ### Claim 13 A method of manufacturing an antenna coupler device, the method comprising: providing a housing comprising a first housing portion and a second housing portion, the housing extending from a housing first end to a housing second end along a central axis, defining a chamber; positioning coils in a stationary position in proximity of the first housing portion and distant from the second housing portion; providing a spiral structure defining threads positioned at the second housing portion; and providing a ferrite rod moveable along the central axis within the first and second housing portions. ### Claim 14 (depends on 13) The method of claim 13, wherein the housing is a cylindrical housing comprising a peripheral wall having an internal surface and an external surface. ### Claim 15 (depends on 13) The method of claim 13, wherein the housing and the spiral structure is made of a non-conductive material. ### Claim 16 (depends on 13) The method of claim 13, wherein the first housing portion has a first length along the central axis, the second housing portion has a second length along the central axis, and the ferrite rod has a third length along the central axis, wherein the third length is equal or smaller to the first length and second length. ### Claim 17 (depends on 13) The method of claim 13, wherein the coils are affixed to an external surface of the first housing portion and surrounding the first housing portion, and the spiral structure is affixed to an internal wall of the second housing portion. ### Claim 18 (depends on 13) The method of claim 13, wherein the ferrite rod comprises two or more ferrite rods coupled to supporting members for forming a unified structure with the two or more ferrite rods for providing solidity thereto. ### Claim 19 (depends on 13) The method of claim 13, wherein the ferrite rod comprises leg members engaging and moving along the threads of the spiral structure.
