Mast antennas, like all electrical components, are particularly vulnerable to water intrusion at connectors. In the extreme, corrosion at unions or terminals can damage a transmitter.
- A crimping tool with matching dies for N-type connectors is available online from most radio equipment suppliers like Quicksilver Radio.
- This N-type connector from Amphenol is more resistant to water intrusion than the industry standard PL259, which needs to be carefully sealed to prevent water intrusion.
- A nearly assembled PL259 connector is ready for soldering. When installed properly, these connectors are rarely a source of power loss, but they must be carefully sealed.
- To seal external connectors, the connector should be filled with coaxial dielectric grease, taped with self-amalgamating tape (shown here) and then taped again with vinyl electrical tape.
- Solderless PL258 connectors are popular among do-it-yourselfers because they are quick to assemble. PS recommends these only for temporary repairs. A coaxial cutter (top) ensures clean, straight cuts.
