PRODUCT OVERVIEW
Mobile Mark’s A55136 is a premium heavy-duty P25 Tri-band Mobile Antenna with a
NO TUNE Design. This Antenna is Vertically Polarized with an omni-directional pattern.
This high quality, high performance antenna is specifically designed for public safety covering
VHF, UHF, TETRA, and 700/800/900 MHz.
This antenna is manufactured using the finest corrosion resistant materials and finishes avail-
able. The enclosed silver-plated phasing coil insures dependable operation. The narrow base
measures 1 3/4” (44 mm) in diameter and has an ultrasonically welded brass insert with a
spring-loaded contact for long term reliability.
This antenna mates with a standard NMO type mount. It comes with a circular rubber gasket
that provides an excellent moisture seal against the NMO Mount. The mount itself is sold
separately and comes with an “O” ring that provides an additional water tight seal.
