HYS
HYS Pre-Tuned Dual-Band NMO Magnetic Mount
One of the more accurately-rated kits in this batch, and a genuinely complete plug-and-play package. Just confirm your roof is steel before ordering.
Proprietary RR score
How we scored it
Performance is derived from the antenna's length in wavelengths on each band it covers, not from the advertised gain. How we score →
Length versus wavelength
What 508 mm Buys You
An antenna radiates according to its length measured in wavelengths, not according to the number on the packaging. Here is where this one lands on each band it covers.
| Band | Wavelength | This antenna | Works out as |
|---|---|---|---|
| VHF146 MHz | 2053 mm | 0.25 λ | quarter wave |
| UHF435 MHz | 689 mm | 0.74 λ | full wave |
Decision helper
Is this antenna right for you?
Yes, if you're…
- ✓Steel-roofed vehicles where drilling is not an option
- ✓Switching an antenna between vehicles
Skip it, if you're…
- ✕Aluminum, fiberglass, or composite vehicle bodies
- ✕Permanent installs (a drilled NMO mount is more secure long-term)
Tradeoffs
The good and the bad
What we like
- Complete plug-and-play kit: antenna, mag base, 5m coax, connector
- Claimed gain matches our model closely on both bands
- No drilling required
- 100W handling
What we don't
- Requires a steel roof or panel; the magnetic base will not grip aluminum or fiberglass
- 20 inches is long enough to need care in garages and low clearances
- 5m of coax is the only length offered, which may not suit every routing

Overview
This HYS kit pairs a 20-inch (508 mm) dual-band whip with a heavy-duty magnetic NMO base, 5 meters of RG-58 coax, and a PL-259 connector, so nothing else needs to be bought. HYS claims 3.0 dBi on 2m and 5.0 dBi on 70cm at 100 watts.
At roughly a quarter wave on 2m and 0.74 wavelengths on 70cm, near full wave, our model lands close to those same figures on both bands, so the claim is a fair one rather than an inflated one. Like every magnetic mount, it only works on a steel roof or trunk with enough surface area under the base; no drilling, but also no substitute for actual metal.

Key Features
- [HYS NMO ANTENNA] Centre Frequency: 144/430;VSWR:< 1.5; Gain: 144MHz (3.0dBi),430MHz(5.0dBi); Maximum Power Input-watts:100W; Antenna length :20inch; The flexible whip is stainless steel;
- [Dual-Band VHF/UHF Versatility] The best of both worlds. Switch to VHF (2m) for superior open-field and long-range reach, or use UHF (70cm) to effectively penetrate buildings and urban structures for ultimate adaptability. This 20.0 inch tall antenna is composed of stainless steel NMO making it durable.
- [Universal NMO to PL259 Setup] Heavy-duty NMO base base mount pre-assembled with an approximate RG-58(5m about 16.4ft) premium RG-58U coaxial cable. Terminated with a standard PL-259 (UHF male) connector, 144/430Mhz NMO Antenna Work for Motorola Kenwood Icom Vertex Blackbox HYT Hytera Mobile Radios. NMO to PL259 working for so239/uhf female Dual Band Radio.
- [Instant Plug-and-Play Setup] No drilling, wiring, or tools required. Simply place the heavy-duty magnetic base on any steel roof or trunk, route the generous 5M (16.4ft) RG58 coaxial cable to your radio, and you are ready to go. Features a soft silicone rubber protective cover that effectively prevents scratches, allowing hassle-free mounting and removal anytime.
- [The Perfect Travel Companion] An ideal heavy-duty mounting solution for Jeeps, trucks, SUVs, and sedans with steel roofs. It gives you the flexibility to easily switch antennas based on driving conditions (e.g., using a low-profile antenna for low-clearance garages or a high-gain one for open terrains) and packs away in seconds when not in use.
