Topband: Cage wire performance

[Kenny Silverman]

Hello and HNY!

I will be converting a wire inverted-L to a T top loading on a 75’ tall wire hung from a tree. To improve the bandwidth, I was wondering about going to a 2-wire “cage” for the vertical section. I’m actually modeling a skinny triangle where the wires connect at a point on the top, but with a 4 foot spread of the wires near the ground. This adds about 15-20 kc to the 2:1 bandwidth per the model. 

Will a 2-wire section like this always behave as a wide/fat conductor or do I have to worry about voltage/current in Each wire?
