While I have no room for Beverages here, it has been interesting to study them and read the posts.  One thing that keeps coming up is that the proper Beverage termination value changes, depending on the amount of moisture in the soil, and other variable factors.

Since the purpose of the termination resistor is to swamp to ground any waves travelling toward it, I would think that a biased diode would do a better job of being more suited to all conditions and frequencies.  This would not work if the terminating resistor is required to allow some current flow in both directions.  A diode placed at the horizontal to vertical wire junction should also prevent vertical wire sig pickup from entering the horizontal wire.

Has anyone tried or considered such a termination?
