The shield ferrule is included in the package (2 pcs: 1 connector, 1 ferrule), so you have everything for one cable end in one bag. ## Duty and Environment The PTFE dielectric holds its dielectric constant across that span — important when the cable sees outdoor thermal cycling or high-power RF heating. The 500-cycle figure is typical for a threaded RF connector; the gold-on-beryllium-copper center contact keeps the contact resistance stable across those mates.","metaTitle":"Amphenol RF 031-4452 TNC Plug, Male Pin, 11 GHz, 50 Ohm","metaDescription":"Amphenol RF 031-4452 TNC plug, male pin, 50 Ohm impedance, 11 GHz max frequency.
