Comet UHV-4 Multi-Band Mobile Antenna 80/40/20/15/10/6/2/70cm HF VHF UHF Mobile Antenna with Fold-Over Design and Adjustable Coils for Amateur Ham Radio Use

The Comet UHV-4 Multi-Band Mobile Antenna is a professional-grade, compact, and versatile antenna designed for operators who demand high performance on multiple HF, VHF, and UHF bands in a single package. Covering 80, 40, 20, 15, 10, 6, 2, and 70-centimeter amateur radio bands, the UHV-4 allows convenient multi-band operation without the need for frequent antenna changes. Built with precision-engineered adjustable loading coils, the UHV-4 ensures excellent radiation efficiency and stable SWR across its wide frequency range. The top telescopic whip and lower band-selectable coils enable fine-tuning for optimal performance, whether used for mobile DX, emergency communication, or local repeater access. Constructed from high-strength stainless steel and aluminum components, this antenna offers superb durability, corrosion resistance, and structural integrity under continuous mobile use. The fold-over hinge design allows quick lowering when entering garages or low-clearance areas—making it a practical solution for daily drivers as well as field operators. With a power handling capacity of 120 watts (SSB) and broadband impedance matching of 50 ohms, the UHV-4 performs efficiently on modern HF/VHF/UHF transceivers. It installs easily using any standard SO-239 mount (or adapter for NMO), and can be paired with various Comet or Diamond mounts for secure placement. Engineered for both portability and full-band versatility, the Comet UHV-4 stands out as one of the most capable mobile multi-band antennas available, delivering strong performance, easy adjustability, and durable construction trusted by amateur radio operators worldwide.
