The word was "resonactor". I have one of his antennas and it works
fine.

I have not examined the resonactor in detail, but I believe it is just
an inductor which is carefully wound to be self-resonant at the desired
frequency, thereby eliminating the need for a separate capacitor to
resonate it. A clever idea, since eliminating the separate capacitor
easily allows full legal power without the expense of a very high
voltage capacitor.

W9INN's trap dipoles are the only ones I know of which advertise full
legal power handling, and that's why I purchased one. I've been running
full power RTTY on mine for five years with no problems.

Since I purchased mine there may have been other full power trap
dipoles come on the market. If anyone knows of one, please reply. I'm
always curious about such things.

It seems like your description.
I do not have an antenna for 160-80.
The DX-LB at $130 looks pretty good.

Yes, that looks very similar to the W9INN design. Should be a good one.

I had one of the Alpha Delta antennas many years ago; the inductors
were wound on ceramic or plastic forms, I forget which, but it was a
very well-built antenna.
