Can I use wirewound resistors to build an HF attenuator?

I need to lose about 5 dB from a 15 Watt exciter. Thanks.
Do you really need to lose some watts? Or do you just need to
reduce the voltage to whatever you are driving? Maybe a capacitive
voltage divider would do what you need.

It's a Tokyo Hy-Power HL-45B amp, designed to be driven with a Yaesu
FT-817. I'm using a "20 Watt" Argonaut V, which isn't terribly linear
at 5 Watts (closer to 3 is actually what's required by the THP).
