[TowerTalk] Making a XM-240 into a 340?

[Gene Fuller]

Hi Gregg-
I've never tried that but I believe that if it's close enough to act as 
another parasitic element it will have to couple into the driven element and 
would most likely lower the feedpoint impedance and you would probably want 
to rematch the feedline. It would be a good project to look at with one of 
the computer antenna programs to look at spacing and tunning of both the 
reflector and director and matching for the driven element, but should make 
a nice yagi. Good luck with it !
