I have been lucky so far, because the B&W Wideband Folded Dipole (a resistor with wires) is pretty flat within 1:1.2 over all bands if I can believe the antenna bridge. The Cushcraft R8 claims to be the same, but I have no experience with it. Putting the LPF between the TX and the tuner was my gut feeling and it does makes sense. > Any low pass filter worth its salt should not create any > non-linearity - It was the KAT100 that I was concerned with for non-linearity. > but again, if it is not properly terminated, the cutoff frequency > may not be where you expect it to be. How very true. Thanks for the feedback. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
