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! Sam WS6S |

You can be well assured that the gain and F/B will fall off much more rapidly. Dale W4OP |
