HYS Dual-Band Magnetic Mount Mobile vs Nagoya UT-72 Magnetic Mount

The Nagoya UT-72 is the better choice here, though the margin is modest.

The single most important difference is VHF performance. The UT-72 reaches a true quarter wavelength on VHF with realistic 2.1 dBi gain, while the HYS falls short at 0.21 wavelengths and 1.1 dBi. On UHF both antennas perform similarly, with the UT-72 hitting a full wavelength versus the HYS at 5/8 wave. The HYS claims 3.5 dBi gain, which overstates its actual electrical length. The UT-72 makes no inflated claims.

At 515 mm the UT-72 is 80 mm longer, which accounts directly for its VHF advantage. Price difference is minimal at five dollars. Owner ratings favor the UT-72 (4.5/5 from 4443 reviews versus 4.3/5 from 370), giving substantially more evidence of what buyers experience.

The HYS suits operators on a tight budget who spend most time on UHF. The UT-72 is the pick for anyone splitting time between bands or prioritizing VHF, and the larger review sample provides better confidence in owner satisfaction. Buy the Nagoya unless budget is your limiting constraint.
