Product Description
Stainless steel antenna spring introduction
Yisen produces 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, and 8.45 inches high for the Mark-7, each in its threaded-end style. These are commercial grade springs of polished, all-stainless construction, except for the internal tinned-copper braid, which bonds their end pieces for high frequency applications.
Each basic size includes springs of three basic styles:
- Threaded at each end, e.g. for mounting a whip antenna. Each of these threaded-end springs has an internal tinned copper braid bond between its end pieces. Each size has one standard thread size, plus other sizes available as options. Please see the specifications for each size for details.
- A "Universal Through Hole" (UTH), at each end, e.g. for mounting an antenna or mast so that a coaxial cable(s) can be passed through the spring. The UTH end has a central hole surrounded by a pattern of 6 threaded mounting holes. This style allows the spring to be mounted on an enclosure (e.g. for a matching or switching function) and in turn, an enclosure, antenna, or mast can be mounted on the spring. Please see the specifications for each size for details.
- A UTH at one end, and a Mast Socket (MSA or MSB) at the other. This allows easy attachment of an antenna, radome, or mast directly to the spring, while allowing passage of the coax(s), control cable(s), etc. The Mark-5 and Mark-6 spring accommodate 1-inch O.D. masts, and the Mark-7 takes a 1.25-inch O.D. Masts are retained with set screws. Please see the specifications for each size for details.
