I realize this is not a tower question, but the antenna gurus hang out here.  
Hopefully some bandwidth can be tollerated for an antenna question. 

I am working on a 160 meter inverted L and having some difficulty getting the 
match correct.  I'd appreciate any input. 

175' total wire length.....100' vertical 75' sloping horizontal 

23 (qty) 130' radials. 

Fed with 75 ohm cable hardline through a variable capacitor. 

I've trimmed and extended the vertical section and adjusted the cap with each 
length change.  The low swr point is always 2.8:1.  Essentially the only thing 
changing is how 

much the capacitor meshes.  

I started with 16 radials and thought adding more would help the match, but it 
has not changed. 

Any Ideas? 

All advice appreciated.
