Seachoice 19811 PL-259 VHF Connector with UG-175 Adapter
The Seachoice 19811 is a convenient combo kit that includes a PL-259 male VHF connector and the UG-175 reducer adapter needed to fit it correctly onto RG-58U coaxial cable — both parts in one package. The UG-175 adapter threads into the back of the PL-259 shell and steps it down to the smaller diameter of RG-58U cable, ensuring a properly fitted, secure termination. Chrome-plated brass construction provides solid corrosion resistance in the marine environment. Buying the connector and adapter together eliminates the common mistake of ordering the PL-259 without the required adapter.
Key Features
- Includes PL-259 male VHF connector and UG-175 reducer adapter — everything needed to terminate RG-58U cable
- Chrome-plated brass construction for corrosion resistance and durability
- UG-175 adapter threads into the PL-259 shell for a properly fitted connection on RG-58U cable
- Minimizes signal loss with a secure, well-fitted termination
- Sold as a matched set — no need to source parts separately
Compatible Applications
- Terminating RG-58U coaxial cable for VHF marine radio antenna connections
- New VHF antenna cable installations on powerboats and sailboats
- Replacing damaged or corroded PL-259 connectors on existing RG-58U antenna runs
- Any application requiring a PL-259 male connector with UG-175 adapter on RG-58U cable
Parts Desk Insights
The 19811 is the combo we recommend whenever a customer is terminating RG-58U cable and ordering a PL-259 connector — it eliminates the very common situation where the connector arrives without the UG-175 adapter and the job stalls. Buying them together is simpler and usually more economical than sourcing the Seachoice 19821 PL-259 Connector and Seachoice 19831 UG-175 Adapter separately. If the customer is running RG-59U cable instead of RG-58U, they’ll need the Seachoice 19841 UG-176 Adapter paired with the PL-259 shell. For a completely pre-terminated solution that skips connector assembly entirely, the Seachoice 19761 (10 ft Cable Assembly) or Shakespeare 35 ft Marine Antenna Cable Kit are worth recommending.
