Brand: Diamond Antenna

The Diamond Antenna AZ507RSP Dual?Band Mobile Antenna is a compact yet capable mobile whip designed to meet the needs of amateur radio operators working in both the 2 meter (144 MHz) and 70 centimeter (430 MHz) bands. This antenna covers both popular VHF and UHF ham bands with a single, streamlined design, offering a flexible solution for mobile stations installed on vehicles including cars, trucks, SUVs, and emergency communications rigs. With a total length of approximately 27.5 in, the AZ507RSP delivers practical height for everyday vehicle use without sacrificing performance. The antenna uses a dual?band radialless design that eliminates the need for separate radials or ground planes in many setups, instead relying on the vehicle body as an effective ground plane. Its gain performance - about 2.15 dBi on 2 meters and up to 4.9 dBi on 70 centimeters - enhances both transmitting reach and receiving sensitivity compared with shorter or lower?gain antennas, making it a good choice for repeater operation, simplex contacts, and general roaming communications. Mechanically, the AZ507RSP features a spring base that helps absorb vibration and reduces stress on the mount in mobile deployments. The integrated UHF PL?259 connector mates easily with standard coax and mounts, simplifying installation with existing hardware and eliminating the need for additional adapters in most cases. The antenna’s typical impedance of 50 ohms and power handling up to 50 W FM make it compatible with many handheld and mobile rigs used by amateur radio operators. Whether you are an amateur radio enthusiast looking to improve your mobile communications capability or a technician outfitting a vehicle for patrol, emergency comms, or public service work, the Diamond Antenna AZ507RSP Dual?Band Mobile Antenna provides balanced performance, ease of installation, and rugged reliability out of the box.

• Diamond Antenna AZ507RSP dual?band mobile whip is engineered for seamless performance on both the 144 MHz 2 meter and 430 MHz 70 centimeter amateur bands, delivering balanced gain and efficient signal transmission for repeater access, simplex work, and general mobile communications
• Approximately 27.5 in (70 cm) length gives a practical balance of performance and vehicle clearance, making this antenna ideal for cars, trucks, SUVs, and mobile rigs where high?gain dual?band connectivity is needed without excessive whip height or drag
• Designed with a robust spring base and integrated UHF PL?259 connector, the AZ507RSP mounts easily to standard mobile mounts while absorbing minor vibration and vehicle movement for greater mechanical durability on the road
• Optimized radiation pattern provides approximately 2.15 dBi gain on 2 meters and about 4.9 dBi on 70 centimeters, improving transmit reach and receive sensitivity compared with typical quarter?wave dual?band antennas
• Rated for up to 50 W power handling with standard 50?ohm impedance and VSWR typically below 2.0 across both amateur bands, the AZ507RSP is suitable for everyday mobile HF/VHF/UHF use with most handhelds and mobile rigs
• Dual?band VHF/UHF design covers 144 MHz and 430 MHz amateur bands with optimized gain
• Approx. 27.5 in whip provides balanced performance without excessive height for mobile use
• Spring base helps reduce mechanical stress and vibration during vehicular operation
• UHF PL?259 connector for standard coax and mount compatibility
• 50 W power handling and 50?ohm impedance for use with most mobile transceivers
