Default K3PF 5 Element 2 Meter Yagi (Radio Shack) SWR Bandwith??

I'd like to hear responses from anyone out there who completed the
K3PF/ Radio Shack 2 Meter beam (QST, July 1999) who can comment on the
2:1 SWR bandwith of the finished product. If it's cut for 144 MHz what
2:1 SWR bandwith can I expect? Or for 146 MHz?

This is a great & simple project but K3PF makes no mention as to what
to expect in this area and I would like to kn ow before I start
cutting.

Please post all replies to the newsgroup...Thanks in advance!

Although I cannot answer your VSWR BW question, it is hardly the most
important factor when judging a Yagi's performance. You can be well assured
that the gain and F/B will fall off much more rapidly.
