Diamond AZ-507R Dual Band Mobile Whip Antenna 2m/70cm, 9dBi, PL259

Diamond AZ-507R Dual Band Mobile Whip Antenna

The Diamond AZ-507R is a compact dual band mobile whip covering 144 MHz (2m) and 430 MHz (70cm) — delivering strong gain on UHF without the bulk of a longer antenna. At just 0.75m, it’s an ideal choice for vehicles where space is tight but performance still matters.

Key Features

• 9 dBi gain on 430 MHz — excellent UHF performance for local and repeater use
• Radialless design on both bands — no ground plane required, clean installation
• Compact 0.75m length — low-profile for everyday driving without sacrificing gain
• 50W FM power rating — compatible with most mobile transceivers
• PL259 connector — direct fit to standard SO-239 mounts
• VSWR <2.0:1 — efficient power transfer across both bands
