Werlatone model C10568 fits your requirements; 30 dB coupling, flat (+/- 0.5
dB) over 1.5 through 32 MHz, 1500 Watts CW, and a directivity of 25 dB. You
won't like the price, but this model shows that a coupler could be crafted
by a hobbyist with the proper design. It's dual directional too, so you
could obtain a VSWR measurement if you wanted it.

Looking for an HF (3-30 MHz) Coupler
for rf measurements. HB or commercial
will do. Accuracy is not important but
flatness would be a concern.

30dB port would do.

Any suggestions ?
