I have a sheet apparently from HyGain many years ago that discusses triband
beams and HyGain's traps in the TH3MK3 and TH6DXX.
This sheet has a schematic of a HyGain driven element with their beta match
and traps, and states that the self-resonant frequency of each trap when
grid dipped out of the antenna to be 27.720 mhz (15m or inner trap) and
20.425 mhz (20m or outer trap).
I suspect TH7 traps would be similar.
