Balun1.1 50 ohm

One red and one gray conductor each form a 100 ohms line on the upper half of the core and also on the lower half of the core. If both lines are connected in parallel, the result is an impedance of 50 ohms for the winding

A Cost Effective Current-mode 1:1 Balun
A cost effective current-mode 1:1 balun can be constructed from a length of coax and a rod typically used for a broadcast antenna loop-stick, some electrical tape, cable ties, a length of PVC water-pipe and some connectors
