Choosing this model
GL401F selection guide
Compare GL401F with GL401C when selecting by antenna clearance. Their listed RF specifications and weight match; GL401F is longer and is explicitly described as a whip in the product data.
If minimum listed length is the priority, GL401C is the shorter candidate. For either model, choose the connector before ordering: BNC and TNC are separate configurations, and the TNC version requires a T suffix after the model number.
