[DX] Help with TA32 Yagi

[anthony costa]

john more than likely your problem is in the coax.disconnect the coax and
check if there's continuity from the center conductor to the braid.if so
your pl259 is closed.re do the connector's.let me know if i was right.good
luck.

> 3. how do I figure out which trap is bad?
