Default twinlead tuning indicators

When I feed twinlead, seems I might use a small fluorescent bulb to show how
it's doing. If a small fluorescent bulb will do this, do I just tune for
"max smoke" while holding it near the twinlead? Can't recall if a small
flourescent bulb will do this or not.

If radiation is cancelled, not sure how it would fire.

I vaguely remember we used to use twin lamps, wired backwards for this
purpose. One way you had SWR on one side; the other way you had SWR on
the other side. Neither light being lit meant good SWR.


I can only relate an experience I had in my house in Minnesota. We had a
long hallway and I could just shuffle my feet and the fluorescent light
I was carrying lit up from the accumulation of charge. Free, well almost
free light. A guy in the S.F. bay area has a house near a radio
transmitter and his garage is pretty well lit by 4 foot tubes he has put
around.
YMMV.
