I
have designed a 2 element HB9CV antenna for 2 meters. I would like
to examine how will SWR, Gain and FB change with changing distance
of phased elements. Results are in the next table: |

| Lambda\ |

Calculation was
made with the same optimization method, in which Gain, F/B and SWR
are with equal weight. Click on the values in the table or on the
points of graph for detailed measure results. |
