Forgot to mention that the tuner in line will attenuate BC for certain.  
Standard tuners will work for normal SWBC work, 3-30 MHz, but there is 
real loss down there below 160 for many tuners (you can check to see 
about high pass vs. low pass vs. bandpass designs to see how much it 
affects you).
