Default EZNEC Model of 88ft doublet

I downloaded the demo of EZNEC4 to see what it would show for a 88ft
doublet 50ft in the air fed by 300ohm twinlead.

My model has two wires each 44ft long joined in the middle at 50ft
elevation with another wire pair 0.1ft long 0.1ft of elevation.

They are joined by two 300ohm transmission lines and a split current
source is placed at the 0.1 elevation junction.

When I run the SWR plot it shows over 100:1 with minima near 2:1 at
6.5Mhz and 11.75Mhz.

Does this sound about right or am I not modeling it correctly?

tnx
