Parts Desk Insights
Best Use Case: This is the right clip for thinner antenna shafts — typically found on shorter VHF whips, flexible antennas, and AM/FM marine antennas — where a mid-point tie-in is needed to stop the shaft from slapping or flexing at speed. It's also handy for routing and securing antenna coax alongside the shaft in a clean, bundled run. If your antenna shaft is larger (5/8" to 3/4"), see the Sea-Dog Marine Antenna Clip – 5/8" to 3/4" instead. For a rigid stand-off support rather than a flush clip, consider the Sea-Dog Nylon Antenna Stand-Off Bracket. Building a full mount? Pair with a Sea-Dog Stainless Steel Deck Mount Antenna Base.
Size Note: Measure your antenna shaft diameter before ordering. Antenna clips are size-specific and not interchangeable across diameter ranges.
