SMA Male Connector for Wireless Antennas
Features & Benefits
Broadband performance DC to 18 GHz with low reflection stainless steel construction and ¼ - 36 threaded coupling offers high performance in a compact design.
Low cost Commercial Grade (Brass SMA) available in nickel or gold plating which provides approximately 30% cost reduction with 250 mating cycles.
Available for. 085" and. 141" diameter semi-rigid cables and all the standard flexible cables including double shielded RG-316.
Phase Adjustable SMA connectors provide ease of mechanical screw adjustments, compared to the delays and expense of laborious cable-trimming.
