Frequency Band Compatibility

FREQUENCY BAND COMPATIBILITY
VHF Antennas (136–174 MHz) Designed for VHF two-way radios operating within the 136–174 MHz frequency range. Well suited to outdoor communication, rural environments, open areas, agricultural operations and compatible marine applications. VHF signals can provide effective coverage over open terrain where obstructions are limited.
UHF Antennas (400–470 MHz and Other UHF Bands) Designed for UHF radio communication in commercial, industrial and urban environments. Commonly used in warehouses, shopping centres, security operations, office buildings and facilities with structural obstructions. The antenna must be matched to the radio’s specific UHF frequency range.
446 MHz / PMR446 Antennas Antennas tuned for compatible 446 MHz radio equipment. PMR446 is a European licence-exempt radio standard with specific equipment and antenna requirements. Regulatory approval and permitted use vary by country, including South Africa.

Portable Antenna Types

PORTABLE HANDHELD ANTENNA TYPES
Stubby Antennas Compact, low-profile antennas typically measuring approximately 5–9 cm. Ideal for retail, hospitality, event management and security applications where convenience and reduced snagging are priorities. Their shorter design may provide reduced range compared with longer antennas, depending on frequency and operating conditions.
Whip Antennas Flexible, full-length antennas commonly measuring approximately 14–17 cm, depending on the frequency band. Designed to provide efficient radio transmission and reception, making them suitable for security, logistics, industrial operations and general outdoor communication.
Helical & Flexible Antennas Flexible antenna designs incorporating helically wound radiating elements or resilient construction. Suitable for demanding work environments where antennas are regularly bent or exposed to physical contact. Common applications include construction, manufacturing, warehousing and industrial operations.

Mobile Vehicle & Base Station Antennas

MOBILE VEHICLE & BASE STATION ANTENNAS
Magnetic Mount Antennas Vehicle antennas with magnetic bases that attach to suitable steel body panels without permanent drilling. Ideal for temporary installations, rental vehicles, mobile security teams and flexible fleet deployments. Performance depends on correct placement and an appropriate ground plane.
NMO Fixed-Mount Antennas Permanent vehicle antenna installations using a compatible NMO mounting system. Commonly installed through a vehicle roof or suitable mounting bracket to provide a secure, weather-resistant connection. Suitable for logistics fleets, emergency services, transport operations and commercial vehicles.
Base Station Dipole & Collinear Antennas Fixed-installation antennas designed for radio base stations, repeater systems and communication infrastructure. Available in omnidirectional configurations for wider-area coverage and typically installed on rooftops, towers or masts. Suitable for compatible Motorola, Kenwood, Hytera and other professional radio systems.
