Gooseneck antenna - an BNC connector base, a flexible mid section and a rigid antenna section on the top third. It flexes with you when weaved in and out of webbing straps on a chest rig or plate carrier and is structurally very strong when paired with an SMA to BNC adapter.
Its a high performance antenna that will upgrade the transmitting range of any dual band VHF/UHF handheld radio regardless of brand and the one I personally use.
