V-H-F TRANSFORMER, 50 Ohms, General Radio Part #: 1000-P5

V-H-F TRANSFORMER, 50 Ohms, Grounded, to 300 Ohms, Balanced, designed to plug into a standard-signal generator having a 50-ohm unbalanced output and to produce an equal, balanced, open-circuit voltage behind a 300-ohm balanced impedance for r-f measurements of f-m and t-v receivers. The transformer is mounted in a cylindrical container terminated at one end in a Type 874 Coaxial Connector and the other in a socket designed to receive the Alden Type HA902P Connector for standard 300-ohm open parallel-wire line. Sourced from military surplus lots.
