Abstract: F-type right angle jack of tap assembly manufactured in a few steps lowering signal loss ratio comprises a bayonet mount, a male connector axially disposed inside the bayonet mount, a right angle connector is in-line coupled to the male connector, a cubic coupling box, corner legs of a metallic frame inserted onto printed circuit board (PCB). The coupling box is directly formed between the bayonet mount and the male connector by injection molding. The coupling box wraps around a tapered tube of the bayonet mount filled with insulation material. A joint of the right angle connector and the male connector is wrapped around by the coupling box, but a proximal end of the right angle connector is exposed outside the coupling box. And a metallic frame squarish in shape formed by stamping and bending is wrapped around the coupling box to facilitate coaxial cable carries signals without loss.

Abstract: A collapsible antenna extends round the circumference, further equipped with an external adapter comprising an antenna base (2) fixed to an electronic device (4) for signal transmission. An antenna body (1) slidly moved with respect to the antenna base (2) is in contact with the antenna base (2) having a stopper end at a proximal end shielded by the antenna base (2), but a free end at a distal end adapted to an external adapter. A plug (50) of an external antenna (5) received in the external adapter, after the antenna body (1) retracts into the antenna base (2), the external adapter (3) is in contact with the antenna base (2). Signal transmission from the external adapter (3) to the antenna base (2) is therefore instead of the same from the antenna body to the antenna base.

Abstract: An antenna 10 with a magnetic sucker 1 is attached to a flat surface by an attractive force or an absorptive force. The antenna 10 is composed of a magnetic sucker 1, a wrapper 21, a coaxial cable 22 and a connector 23. In turn, said magnetic sucker 1 consists of a magnetic bolt disk 11 and a soft elastomer cone-shaped disk 12. One end of the coaxial cable 22 is used as a first end 22a to receive signals; the other end is a second end 22b to transmit signals. Said first end 22a includes an external conducting line 222 being exposed out and folded back to wrap around the perimeter of the external insulation layer 221, an inner insulation layer 223 exposed out of said external conducting line 222, and an inner conducting line 224 exposed out of said inner insulation layer 223.
