Yes Jim, and that is what I do, sell transformers. Just trying to locate some cable and let others know adaptors are available.

Thanks, it's always good to find maybe a better adaptor source and more resaonable price.

To connect what to what?  Why?

If it's for RX and the ends are unbalanced (that is, one side grounded), he'll need some form of transformer or other circuitry to make a balanced connection.

There are female F to male PL259 adapters (most I've seen are el-cheapo), and I've seen female F to RCA, and female F to 2-ckt (T-S) 1/8-in male. I think Fry's stocks them.
