The EhubAmerica TX-AM-450-70 is a UHF mobile antenna engineered for operation across the 450–490 MHz band, making it well-suited for land mobile radio deployments in public safety, utilities, transportation, and commercial fleet environments where reliable UHF coverage is essential. With a 2.4 dB gain rating and a 200 W maximum power handling capacity, the antenna is built to work alongside high-output mobile radios without thermal or electrical stress. Its field-adjustable tuning capability allows technicians to optimize resonance on-site without returning the unit to a shop, reducing downtime during installation or re-deployment. The compact 29 cm overall length minimizes wind load and vehicle profile while maintaining effective radiated performance across the full 40 MHz operating bandwidth. Mounting is accomplished via a standard 3/4" NMO58UNC interface, one of the most widely adopted mobile antenna mounting standards, ensuring broad compatibility with existing vehicle mount hardware.

Key features & benefits

  • 450–490 MHz UHF Coverage — Covers the full 40 MHz span of the upper UHF land mobile band, accommodating a wide range of licensed channel assignments in a single antenna element.
  • 2.4 dB Gain — Provides modest directional gain over a unity reference, improving signal efficiency for mobile-to-base and mobile-to-mobile paths in typical vehicular operating environments.
  • 200 W Power Handling — Rated for up to 200 W of continuous transmit power, supporting high-output mobile radio installations without risk of antenna damage or performance degradation.
  • Field-Adjustable Tuning — Allows on-site resonance adjustment to dial in optimal SWR for a specific operating frequency within the band, eliminating the need for bench tuning or antenna replacement when channel plans change.
  • Compact 29 cm Length — The short overall form factor reduces aerodynamic drag and keeps the antenna profile low on the vehicle roof or trunk, practical for fleet operators with clearance or aesthetic constraints.
  • 3/4" NMO58UNC Mount Interface — Uses the industry-standard NMO mount footprint, providing a secure, weather-resistant base connection compatible with widely available NMO mounting hardware across vehicle types.
