The ZCG Scalar B19-SAR-164 is a ruggedised broadband VHF high band coaxial dipole antenna purpose-built for dependable fixed-site communications across the 148?174 MHz VHF band, a spectrum widely used by emergency services and critical response networks. Designed for mission-critical environments, this antenna delivers consistent omni-directional coverage while maintaining exceptional mechanical strength and long-term reliability in harsh outdoor conditions.
Featuring a true 0 dBd (2 dBi) gain pattern, the B19-SAR-164 provides uniform signal distribution, supporting reliable local-area coverage where even radiation is essential for coordinated field operations. Its broadband design enables operation across the full VHF high band without retuning, making it well suited to multi-channel emergency service systems, repeater sites, and command or staging locations. With a 100 watt power rating, it comfortably supports typical VHF land mobile radio transmit levels used in public safety and volunteer emergency networks.

The coaxial dipole construction enhances radiation pattern stability and reduces interaction with supporting structures, ensuring predictable performance when mounted on masts, buildings, or portable emergency infrastructure. Built for permanent outdoor deployment, the antenna?s ruggedised design helps it withstand extreme weather, vibration, and long service intervals with minimal maintenance.
For secure installation, ZCG Scalar recommends mounting the B19-SAR-164 using at least two EB1-SS stainless steel parallel mount clamps. Where narrow channel selectivity or interference mitigation is required, pairing with a suitable VHF cavity filter, such as ZCG Scalar?s ZVBPF-136174 single channel cavity filter or stackable ZVCF-136174 through pass multi-channel filters, can further optimise system performance.
