PL-259 UHF Male Plug to TNC Female Jack RF Adapter Connector

📋 Overview

This PL-259 UHF male plug to TNC female RF adapter lets you connect an SO-239 (UHF female) jack to a TNC male plug or cable end. It's a straight barrel-style adapter with a UHF male plug on one end and a TNC female jack on the other, so it joins two connectors that would otherwise never mate.

It has a nickel-plated brass body, a teflon (PTFE) insulator and gold-plated copper center contacts. It's a handy fit for SDR, HAM, GMRS and commercial radio setups, antenna jumpers and 50 Ohm coax runs.

⭐ Key Features & Benefits

• UHF Male to TNC Female — PL-259 (UHF male) plug on one end and TNC female jack on the other, so it connects an SO-239 female jack to a TNC male plug
• Nickel-Plated Brass Body — Tough, corrosion-resistant housing that holds up to repeated connecting and disconnecting
• Gold-Plated Copper Center Contacts — Gold plating resists oxidation and helps keep the signal connection clean and reliable
• Teflon Insulator — Rigid, stable dielectric that holds the center contact in position in both connectors
• 50 Ohm Impedance — Matches standard 50 Ohm coax cable and radio equipment
• Threaded Connections — Both ends screw together for a secure fit that won't pop off, unlike push-on or bayonet styles

📊 Specifications

📦 What's in the Box

• 1× PL-259 UHF Male Plug to TNC Female Jack RF Adapter

📝 Note: Coax cables, plugs and radios are not included. This adapter has a UHF male plug on one end and a TNC female jack on the other, so check that your two connectors are an SO-239 (UHF) female jack and a TNC male plug.

🔌 Compatible With

• SO-239 UHF female jacks, including common SDR and HAM radio, antenna and SWR meter connections
• TNC male plugs on antennas, radios, jumpers and coax cables
• 50 Ohm coax cable and RF systems
• Equipment with a TNC male connector that needs to connect to UHF (SO-239) equipment or cabling

🎯 Common Applications

• SDR & HAM Radio — Connect a radio or antenna with an SO-239 jack to a TNC-terminated cable or antenna
• Antenna Systems — Mix and match antennas, jumpers and feedlines with different connector types
• Communication Systems — Bridge UHF and TNC connectors in two-way radio and other RF setups
• Audio & Video Transmission — Join coax cables and equipment that use different connector types
• Security & Data Signal Transmission — Adapt cabling for equipment that uses TNC connectors

🚀 Getting Started

Using the adapter takes about a minute and needs no tools:

1. Confirm that your connectors are an SO-239 (UHF) female jack and a TNC male plug.
2. Thread the PL-259 end of the adapter onto the SO-239 jack until it is snug.
3. Thread the TNC male plug onto the TNC female end of the adapter.
4. Tighten both connections by hand. Don't use pliers on the knurled coupling nuts, which can damage the plating and threads.

💡 Tip: TNC and BNC connectors look similar and are both 50 Ohm, but TNC uses a threaded coupling and BNC uses a quarter-turn bayonet lock. If your plug twists on and locks with a quarter turn, you need a BNC adapter instead.
