With QRP a good antenna can often help. At the same time many rigs lack tuners.
Amateur Radio Weekly reminded me that a 6dB attenuator drops the power 4 times but always ensures that the load seen by any PA is always less than 1.67:1.
If you can accept this loss and the attenuator is suitably rated, this may be an acceptable solution e.g. for WSPR beacons.
