[Elecraft] K3 Ant 1 and Ant 2 Isolation?

[dave]

Probably not a good idea.

The interaction between the vertical and the feed to the G5RV will be 
severe. You will have large quantities of RF forced onto the G5RV feeder.

I ran a quick EZNEC model of 2 verticals 2.4" apart. It indicates that 
at 100w you would induce 45w onto the feeder. Even QRP levels would 
not appear to be safe. I'd think you are pretty assured of blowing 
something up.

It would be an interesting experiment though, if you wanted to try it 
and report back on what burned up . . .
