Q: Can it be used as a VHF antenna?

Asked by: Al V - 7/18/2021

A: Based on the manufacturer's specs found here: https://shakespeare-ce.com/marine/product/5250-skinny-mini-vhf-ais-antenna/, it will work ok as a VHF antenna.
SWR: nominally 1.5:1 at 162 MHz
Bandwidth: 7 MHz within 2.0:1 VSWR
So the bandwidth extends over the VHF marine frequencies with acceptable VSWR of 2:1.
