| AVM-450 | 450MHz UHF Vehicle Mount Antenna | 330-512MHz | 3 dBi. |  |  |  |
The AVM-450 is a heavy-duty UHF vehicle mount whip antenna designed for high-performance mobile operations in the 330 – 512 MHz frequency range. Unlike the VHF models, this antenna features a 1/4 wavelength radiating element and comes standard with high-quality LMR-200 cable to maintain signal integrity at higher UHF frequencies.
Key Design Features
- UHF Optimization: Specifically tuned for the 400MHz band, providing a solid 2.5 dBi omnidirectional gain when mounted on a metallic ground plane.
- Low-Loss LMR-200 Cable: Supplied with 3.5 meters of LMR-200, offering significantly lower attenuation at UHF frequencies compared to the standard RG-58 used on lower-band models.
- Versatile Mounting: Supports two installation methods:
- Side Mounting: Using the supplied "L" bracket and self-tapping screws.
- Thru-Hole Mounting: Direct chassis installation via a 16mm diameter hole.
- Durable Construction: Built with an aluminum base, a Nylon coil housing, and a 3.5 mm stainless steel whip for long-term outdoor reliability.
