Hi

Ok, we’re talking about a NE-52 that does *not* have both leads connected. One side goes to the antenna and the other is just hanging open. Hooking one to the antenna and the other to ground would be “another way” to do it. Assuming the “not connected” is correct ….

The bulb is going to light based on the EM field it’s in. Put it next to a 1/4 wave antenna at 10 GHz, you get a very different field than next to your 160M :) 1/4 wave. Put it at the tip of the 1/4 wave and it will see a different field than down at the base. 

Lots of variables ….

Strange question to the group, but here goes:
Do you have experience with how many watts are needed of HF power to a high Z antenna point, for a small neon bulb to light?
Say an NE-52 ? I think those are rated 1/50 watt. They will light with static built up from getting up from a chair, if your shoes
are well insulated material. I think as an RF indicator, one wire goes to the antenna point, the other just hangs unconnected.
Altho i did see one schematic that showed besides the connection to the high Z antenna point, a wire between the two neon bulb leads. ( It occurred to me an easy answer would be, “enough voltage to give you a white burn mark on your hand”, but i’m looking
for some actual number, with wide % latitude. )
