13.56mhz rfid coil antenna springintroduction
Yisenproduces a family of mobile antenna springs comprising the Mark-5,Mark-6, and Mark-7. These model series represent three basic sizes:4.65 inches high for the Mark-5, 6.9 inches for the Mark-6, and8.45 inches high for the Mark-7, each in its threaded-end style.These are commercial grade springs of polished, all-stainlessconstruction, except for the internal tinned-copper braid, whichbonds their end pieces for high frequency applications.
Eachbasic size includes springs of three basic styles:
- Threaded ateach end, e.g. for mounting a whip antenna. Each of thesethreaded-end springs has an internal tinned copper braid bondbetween its end pieces. Each size has one standard thread size,plus other sizes available as options. Please see thespecifications for each size for details.
- A "UniversalThrough Hole" (UTH), at each end, e.g. for mounting an antenna ormast so that a coaxial cable(s) can be passed through the spring.The UTH end has a central hole surrounded by a pattern of 6threaded mounting holes. This style allows the spring to be mountedon an enclosure (e.g. for a matching or switching function) and inturn, an enclosure, antenna, or mast can be mounted on the spring.Please see the specifications for each size for details.
- A UTH at oneend, and a Mast Socket (MSA or MSB) at the other. This allows easyattachment of an antenna, radome, or mast directly to the spring,while allowing passage of the coax(s), control cable(s), etc. TheMark-5 and Mark-6 spring accommodate 1-inch O.D. masts, and theMark-7 takes a 1.25-inch O.D. Masts are retained with set screws.Please see the specifications for each size fordetails.
