Quoting Doug Waller <NX4D@comcast.net>:
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.
Doug, IMHO any kind diode in a long wire such as a Beverage is formula for
disaster with detection, rectification and intermod generation. Even disimilar
metals are bad enough problems in garbage generation in weak signal
reception. Why make it easier for unwanted signals to make there way to your
receiver?
