I have also used a double pairing of Forward & Reverse Diodes to act as a low voltage shunts along with the NE-2 Neon Bulb as the Higher Voltage Shunt and the 10K Ohm Resistor for Static Bleed-Off. Neon tubes "fire" at around 80-110V. Can your front end take this? Older tube rigs can, not sure I would bet on a FET front end. A pair of diodes right on the input can be disastrous. They are a nonlinear device, easily driven into generating all sorts of mixing products- as they are right at the antenna, everything from local AM, FM and TV will be seen by the diodes.
