[Elecraft] OT a bit: K3 Ant Tuner

[Don Wilhelm]

Rich,

Yes and no.  With 2 antenna tuners in-line, there will be a bit more 
loss due to inductor winding resistance, but other than that, it should 
do harm.

Several bandpass filters indicate that they should be between the rig 
and the tuner (so the bandpass filters are not run at a high SWR).
If the power rating of the bandpass filter is marginal with respect to 
the rig power, then I would observe that caution. Refer to the bandpass 
filter specs.
