30m should certainly be well within the range of the "universal"
dipole design. Presumably the gain/beamwidth numbers you quote come out of a model. For completeness, what does the model say the average gain is in the OTHER 180 degrees (the nulls)? 73, Ed "Cecil Moore" wrote in message ...

It's main lobes are broadside with a gain of 9 dBi, a TOA of 34 deg, and a horizontal beamwidth of 33 deg. Off the ends, the gain is 3 dBi with a horizontal beamwidth of 60 deg. In other words, it has gain over a ground mounted quarter-wave monopole in 4 directions for more than 180 degrees of the horizontal. -- 73, Cecil http://www.qsl.net/w5dxp |
