The straight body keeps the signal path in line, so the adapter adds no right-angle bend to the RF route. ## RF Performance and Dielectric The PTFE dielectric maintains a stable dielectric constant across the band, so the impedance step through the adapter stays within a usable window for sub-4 GHz signals — think Wi-Fi, cellular, ISM-band, or instrumentation links. Above 4 GHz the mismatch loss climbs; this part is not specced for higher bands. ## Dual Locking: Bayonet and Threaded The BNC end uses a bayonet lock — quarter-turn mate, push-and-twist, no tool needed. The SMA end uses a threaded hex-nut coupling. The adapter body carries both locking styles on the same straight shell, so the BNC side can be quick-connected while the SMA side stays torqued down. The brass and stainless steel body with nickel and passivated finish resists corrosion in field-service or lab environments. ## Temperature Range and Contact Plating That covers outdoor antenna feeds, engine-compartment test points, and environmental chambers. Free-hanging (in-line) mounting; no panel hole or PCB footprint required. For a form-fit-function cross, look for a between-series BNC jack to SMA plug adapter in a straight body, 50 Ohm, with the same PTFE dielectric and gold-plated beryllium copper centre contacts.","metaTitle":"TE 1058083-1 BNC to SMA Adapter, 50 Ohm, 4 GHz, Obsolete","metaDescription":"TE 1058083-1 BNC jack to SMA plug adapter, 50 Ohm, 4 GHz, -65 to 125°C.
