STI-CO's Dual Port Roof Mount Antenna for public safety vehicles allows simultaneous two-band operation from just one antenna in VHF and 700/800 MHz bands, significantly reducing installation time and expense. It works very well with the new multi-band radios that provide instant interoperability for mission critical public safety responders. Easy to install, it fits on standard NMO mounts. The integrated coupler accepts two feed lines for separate VHF and 700 MHz radios. Optional customized cable kits are also available.
