Topband: Inverted L Question

[Herb Schoenbohm]

Mike,  You would be much better off by feeding the tower with a shunt or 
cage feed.  As K2AV so accurately pointed out...an inverted "L" 
supported by a metal tower is not the answer for an efficient system on 
160.  With the amount of radials you have at the base you could do much 
better by feeding the grounded tower.  I presume the tower has a beam on 
the top and that will really make you system even more efficient by 
providing some good toploading.  An inverted L supported by a steel 
tower is not the best solution. It is probably the worst of all compared 
to a Marconi "T" out in the clear even with the same tower used to 
support one end as far away a possible from the vertical wire.
