Hy-Gain now includes an addendum with the TH7 that says:
When using RTTY (ASCII, AMTOR, Baudot, Packet, etc.) on this antenna with
the Hy-Gain BN-86 50 ohm balun, DO NOT exceed 500 watts continuous output
On SSB and CW, which exhibits a lower duty cycle, this antenna with the
BN-86 will easily handle 1500 watts PEP, or 800 watts average power output.
If higher power levels than these are anticipated, it is recommended that a
coaxial RF choke or a torroid-type balun be used.
The Hy-Gain BN-4000B will handle continuous output at legal limit. It works
well, but costs close to $100.
