HYS NMO Magnetic Mount Base
If you are buying an NMO antenna you need a base for it, and this is the sensible default: strong enough for highway use, cabled and ready, and cheap enough that the decision is not worth agonising over.

Decision helper
Is this antenna right for you?
Yes, if you're…
- ✓Anyone pairing a mobile or GMRS radio with an NMO antenna
- ✓Renters and leased vehicles where drilling is not an option
- ✓Moving one antenna between several vehicles
Skip it, if you're…
- ✕Aluminium, fibreglass or composite roofs
- ✕Permanent installs, where a lip or through-hole mount is tidier
Tradeoffs
The good and the bad
What we like
- No drilling, wiring or tools; moves between vehicles in seconds
- 16.4 feet of RG58 coax already fitted
- 30.8 pounds of pull from a compact 90mm magnet
- Standard NMO fitment, so any NMO antenna threads on
What we don't
- Needs a steel roof; aluminium and composite panels defeat the magnet
- Coax runs through a door or window seal unless you route it properly
- The base itself contributes nothing to gain, only to ground plane

Overview
This is an NMO magnetic base with 16.4 feet of RG58 coax already attached, so it takes any NMO antenna and needs no drilling, no wiring and no tools. The magnet is 90mm across and rates 30.8 pounds of vertical pull, which is enough to hold at highway speed, and a silicone cover under it keeps the paint intact when you move it between vehicles.
A mount does not radiate, so it has no gain and we do not score it. What it does is more valuable than gain: it puts the antenna on a metal roof, which buys you both height and a proper ground plane, and those are what actually decide how far you reach. Watts do not move your horizon; the roof does. The one requirement is steel. Aluminium and composite roofs defeat a magnet entirely, and on those you need a lip mount or a through-hole install instead.

Key Features
- INSTANT PLUG-AND-PLAY SETUP - No drilling, no wiring, no tools. Just set the heavy-duty 90mm magnetic base on any steel roof or trunk, route the 16.4ft RG58 cable to your radio, and go. The soft silicone pad protects your paint from scratches while the compact base mounts and removes in seconds, so you can move it between vehicles anytime.
- HIGH-SPEED STABILITY - A 3.54-inch (90mm) magnetic base with 30.8 lbs of vertical pull holds your antenna firmly planted at highway speeds and on bumpy off-road trails. No more worrying about your antenna sliding or flying off at 70mph. Engineered for daily commuters, truckers and overlanders who need reliable performance mile after mile.
- UNIVERSAL NMO COMPATIBILITY - Standard professional NMO connection works with virtually every NMO antenna on the market, for Midland GMRS/FRS models like the MXTA25 stubby and MXTA26 long-range, for Motorola, ICOM, Kenwood, Larsen and Maxrad. Swap any NMO antenna in seconds to match your coverage needs.
- EXTENDED REACH & CRYSTAL-CLEAR SIGNAL - The 16.4ft (5M) premium RG58 coaxial cable with PL-259 plug reaches from roof to dash with room to spare, making hidden routing through door jambs and grommets easy on cars, trucks, SUVs and vans. Stable 50-ohm impedance keeps SWR low for clean, reliable transmission and reception.
- THE ALL-WEATHER TRAVEL COMPANION - One mount, endless flexibility: switch between a low-profile antenna for parking garages and a high-gain whip for open highways in seconds. Packs away in seconds when not in use. The scratch-proof silicone cover and waterproof design keep it ready for rain, snow, dust and extreme weather on every adventure.
