The R-1A utilizes an external locking design. This design allows the manufacturing process to be more automated, thus reducing the cost. A benefit of the external locking mechanism is its added ruggedness. We recommend that you use solder when processing your cable assemblies with these connectors, but they do allow for crimping with the appropriate tool. Every antenna should have a spring.
Springs protect the antenna, mount and vehicle.
These springs are made from long lasting, top grade electro-polished stainless steel.
