Choosing this model
GL401A selection guide
Choose GL401A when a 200 mm antenna can be accommodated; compare GL401F if the available clearance calls for a much shorter whip. The listed gain difference is small, so it should not outweigh a physical fit or connector requirement.
GL401A and GL401F share the same listed operating range, bandwidth and power limit, but differ substantially in length. Specify BNC or TNC when ordering; the TNC configuration uses a T suffix after the model number.
