Tt is possible to solder RF connectors to cables. Soldering RF connectors to cables is a common method of creating a secure and reliable electrical connection. However, it requires proper technique and attention to detail to ensure a successful and high-quality solder joint. Here are some steps to follow when soldering RF connectors to cables:

1. Strip the Cable: Begin by carefully stripping the outer jacket of the cable to expose the inner conductor and shielding (if present). Use a cable stripping tool to ensure precise and clean cuts without damaging the inner components.
2. Trim the Inner Conductor: Trim the exposed inner conductor to the appropriate length, following the specifications provided by the connector manufacturer. The length of the exposed inner conductor should match the requirements of the connector to ensure proper electrical contact.
3. Prepare the Shielding: If the cable has shielding, carefully separate and prepare it. Fold back the shielding and ensure that it does not come into contact with the inner conductor.
4. Slide on the Connector: Slide the connector over the prepared cable, making sure the inner conductor is properly aligned with the connector’s pin or contact. The connector should fit securely onto the cable without excessive force or play.
5. Soldering: Apply heat to the connector’s body using a soldering iron while simultaneously applying solder to the joint between the connector and the inner conductor. Ensure that the solder flows smoothly and creates a secure bond. Be mindful of not overheating the connector or melting any insulating materials.
6. Shielding Connection (if applicable): If the cable has shielding, solder the shield to the connector’s outer conductive housing or grounding contact. This helps provide a proper electrical connection and maintains shielding effectiveness.
7. Insulate and Protect: After soldering, insulate the soldered joint and any exposed parts of the cable using appropriate insulating materials, such as heat shrink tubing or electrical tape. This helps protect the soldered joint from moisture, mechanical stress, and potential short circuits.
8. Post-Soldering Inspection: Once the soldering is complete, visually inspect the soldered joint to ensure it is properly formed, without any solder bridges, cold solder joints, or loose connections. Perform continuity testing or use appropriate testing equipment to verify the electrical integrity of the soldered connection.

It is important to note that soldering RF connectors to cables requires precision and attention to detail. If you are unfamiliar with soldering techniques or lack experience, it is recommended to seek assistance from someone with expertise in RF connector soldering or consult a professional technician to ensure a reliable and high-quality soldered connection.
