[Lowfer] Question : Hanging Vertical drop wires on a HorizontalTop Load

[Michael Sapp]

Andy: Download the free version of EZNEC and run some simulations. It is 
limited to 20 wire segments, but you can simulate plenty of simple wire 
antennas within the 20 wire segment

constraint. It will also help you to better grasp the "j-ohm" concept .... 
The EZNEC demo program comes with a collection of simple antenna models 
which you can modify in the wire table to

get a feel for how the program works.  It takes alittle bit of effort to 
figure out, but it is not a steep learning curve like Spectrum Lab....

If you terminate the "hanging wire" into a resistive load to ground you get 
something resembling an inverted "U" antenna....
