Topband: A question on L's

[Guy Olinger, K2AV]

The NEC4 model I quoted was for #12 wire (which alas I failed to mention) and 
was only to demonstrate that the bandwidth issue was not anything inherent 
about an ideal 1/4 w vertical vs an ideal 1/2 wave dipole, all other issues 
held constant.

In the model, the perfect ground does not have loss or radiate, only the 1/4 
wave #12 wire.

I suspect it has something to do with the behavior of good ole dirt in the 
vicinity, as apparently does W4BZ.  REAL DIRT, and stuff buried in it, is a 
real Achilles heel in antenna model programs, including NEC4.

Maybe there is something that NEC4 overlooks. It seems unlikely that
many wires in parallel have the same bandwidth as a single wire.
