SWR 350556 3-1/8″ Eia Field Flange

$134.00

The SWR 350556 is a premium 3-1/8″ EIA Field Flange (Unflanged Adapter), expertly engineered to convert an un-terminated 3-1/8″ rigid transmission line into a standard EIA flanged connection. Developed to give broadcast professionals a highly reliable and rapid field-connection solution, this product brings outstanding structural integrity and electrical efficiency to custom line runs. It maintains a precise 50-ohm impedance, ensuring ultra-low VSWR across demanding high-power FM, TV, and telecom applications.

What makes this product exceptionally valuable for on-site installations is its NO SOLDER REQUIRED design. The SWR 350556 comes as a complete assembly equipped with a heavy-duty line clamp and a full hardware kit. This allows station engineers and tower crews to cut rigid coax to length in the field and securely attach a standard EIA flange using mechanical pressure rather than brazing or hot work, saving critical time during emergency repairs and custom routing.
