Any recommendations re adding 80m to an existing 160m inverted L? Would it be 
better to:
   
  1)  insert a coax trap 
  2)  Tue the antenna at the base (LC network)?
   
  My concerns are if the coax trap will decrease 160m performance? If I 
impedance match it at the base, it will be a 1/4 on 160 and 1/2 wave on 80m. 
The problem there being 1/2 wave verticals usually are asociated with line 
radiation problems.
