The only thing I disagree with about Tom's advice is that, with the 
exception of a VERY large string of #73 beads (at least 100 beads), 
beads are useless on HF, and even those are not very useful at 2 MHz.  
Where Tom recommends beads I would instead use either 1) a transformer 
having VERY low inter-winding capacitance, or 2) a common mode choke 
formed by winding at least 16 turns of the coax around a #31 core.
