[TowerTalk] ? Yagi Interaction on 15m: KT34XA and XM240

[Bob Otto]

Hello Jeff,

I'm really interested in the responses to this question.  Some years
ago I set up a pair of 13B2's using a MFJ 259.   I love the tool, but
have to admit that everything looked great when I tested it, but in
use, it shouwed a much different story.  Never did figure out why the
change.

I'm putting up a Force12 C31XR, MAG240N, and a WARC 2/2 and am
interested if the MFJ 259 will do the proper job of measuring.

73's from.......
