The Diamond HV5S is a premium 5-band mobile antenna engineered for versatile vehicular installations operating across several popular amateur radio bands. By consolidating five distinct frequencies—7MHz (40m), 21MHz (15m), 50MHz (6m), 144MHz (2m VHF), and 430MHz (70cm UHF)—into a single high-performance vertical whip, this antenna eliminates the need to mount multiple elements on your vehicle. The lower base terminates in a standard MP (PL-259 compatible male profile) RF connector, facilitating a direct and physically secure attachment to standard heavy-duty mobile mounts.
The electrical design of the HV5S optimizes wave propagation across all five bands to deliver reliable performance. The radiating structure operates as a 1/4 wave element on the 7, 21, 50, and 144MHz bands, and transitions to a high-efficiency 5/8 wave element on the 430MHz UHF band to offer a localized gain rating of 3.2dBi. It supports high-power transceiver outputs with a maximum power rating of 120W SSB on the lower bands (7/21/50MHz) and up to 200W SSB on the higher bands (144/430MHz). SWR parameters remain tight, measuring at less than 1.5:1 on 50/144/430MHz and less than 2.0:1 on the HF bands (7/21MHz) at resonance.
