Pl259 Connectors are used to attach your antenna to your VHF radio. They are one of the most commonly used connectors for VHF radios. Need to lower your mast? Look for male and female connectors combined with an extension cable to allow you to disconnect your antenna when you lay your mast down. Hearing static on your VHF radio? Try replacing the connector at the end of the wire before replacing your entire VHF radio or antenna. We have cables from Ancor, Seachoice, and Shakespeare.
