  Stealth Antenna

Sinclair's concealed bumper mount antennas SHA211, SHA311, and SHA411 series are designed for law-enforcement vehicles. The antennas are hidden and weatherproofed.

The antenna is integrated with a 17 feet RG58 feed cable. In addition to the N male connector attached to the RG58 cable, three separate connectors are supplied with the antenna including N male, UHF male and mini UHF male.

Attention: The antenna must be installed and weathproofed properly following the installation instructions. For particular vehicles or wideband applications, please contact Sinclair sales representative or CSR for custom designs to achieve the optimum performance. Dual antennas (one in the front bumper and one in the rear) can be used for better omni coverage.
