Heavy Duty Magnetic Antenna Mount 8.8in SO239 Base - Strong Hold

In this review the UAYESOK Heavy Duty Magnetic Antenna Mount proves to be a straightforward, purpose-built accessory for mobile radio users who need a secure, easy-to-install antenna base. The single biggest reason to buy is its unusually strong magnetic hold: a 30KG suction rating and rubber-padded magnet deliver stability and finish protection, making it a reliable choice for temporary or semi-permanent vehicle installs on flat steel surfaces. It is best for operators who want a no-drill mounting option with a long RG58 lead already fitted.

Key Features

• 8.8in heavy duty magnetic base: A large 90mm diameter base provides a broad contact area that helps keep the mount steady under movement and wind load.
• 30KG suction strength: The strong magnetic pull gives confidence that the antenna will remain attached during highway driving and rougher conditions.
• SO239 antenna connection: A female SO239 connector accepts PL-259 male antenna plugs used on CB, HF, VHF and UHF mobile antennas without additional adapters.
• 5m RG58 coax cable included: The 16.4ft low-loss RG58 with PL-259 plug gives ample reach from roof or trunk mounting points to most mobile radios.
• Soft rubber on magnets: Rubber padding prevents surface scratching and helps the base sit more securely on painted steel.
• Simple install and removal: The magnet-and-rubber design means quick setup and no permanent modification to the vehicle when used on compatible metal surfaces.

Who It's For

The mount is ideal for amateur radio operators, CB users and field communicators who need a strong, temporary vehicle antenna solution that avoids drilling or permanent brackets. It suits users who have a flat steel surface on which to place the magnet and who value a ready-to-go coax lead and PL-259 connection.

It is not intended for use on aluminum, titanium or plastic surfaces, so owners of vehicles with non-ferrous roofs or who require a permanent weatherproof roof installation should look at permanent mounts or bolt-on solutions instead.

Pros & Cons

Pros

Frequently Asked Questions

Will this mount scratch my car?
The base has soft rubber padding to protect paint, but care should be taken to keep surfaces clean and inspect for debris before mounting.

Can I use this on an aluminum roof?
No; the magnet requires a ferrous metal surface and will not work on aluminum, titanium or plastic surfaces.

Does it work with handheld radios?
The mount uses an SO239/PL-259 connection and 5m RG58 cable; adapters are needed to interface with most HT handheld radio connectors.
