I was thinking Bi-directional.
Oh, OK; good. Thanks for the clarification, Bob.

Thanks for the new photos.

Please let us know if you make any improvements.

There is one thing I don't like about the Solid Signal Xtreme Signal HDB91X. The coax connector on the balun doesn't make good contact with the center conductor of the coax; it doesn't grasp the wire firmly. I noticed that when I was making resistance measurements of the driven element. I consider that a design defect. I inserted a short length of 18 gauge wire in the connector to make the measurement, which is the same gauge as the center conductor of RG6 coax.
