Default Can I use wirewound resistors to build an HF attenuator?

A 5db T attenuator with 15 W in has the maximum dissipation in the shunt
resistor at about 5 W.

The input series resistor dissipates about 4 W and the output series
resistor dissipates a little over 1 W.

I see no reason to go to wirewound resistors at these power levels.



What kind of 5 Watt resistors should I use?
