![]() The solid horizontal line represents the earth and the plotted values are normalized so that the maximum value, represented as zero db, coincides with the outer edge of the chart. For example, in the plots a horizontal dipole the antenna itself would extend horizontally across the page. The antenna radiation plots used in this document show the vertical plane radiation pattern of the antennas as viewed broadside. For most of the Buddipole configurations there is significant radiation at these low s even when the maximum gain of the antenna is at a much higher radiation, thus it is possible that a user may make distant contacts even though the selected Buddipole configuration may not be optimal working DX on the chosen band. The reader should note that take-off s of less than 30 degrees are preferred DX. Under the right propagation conditions lower signals will propagate further as the resulting skip distance of the reflected signal is greater. For low height antenna applications antenna elevation (sometimes referred to as take-off ) is often a more important factor than gain in determining success in DX communication. The purpose of this document is to assist the Buddipole user in making decisions on the usage of these different configurations, depending on the antenna support height, the chosen band of operation and the operating objectives (working DX, domestic contacts or short range NVIS contacts). ![]() Cebik.ΔΆ BUDDIPOLE CONFIGURATIONS Introduction Using the accessory Rotating Arm Kit the Buddipole may be erected in a number of different configurations, the most useful being the Horizontal Dipole, Vertical dipole, L and Upward Vee antennas. Michael Babineau VE3WMB based on the earlier modeling work on the Buddipole by Mr. 1 Effective use of Buddipole Configurations* BUDDIPOLE ANTENNAS P: / F: * Note: This report has been condensed and revised by Mr.
