 ```The G5RV is a 100 foot center fed wire antenna. Think of it as a long wire for each band and look up the patterns for each length in the ARRL Antenna Book or other source. 80M .35 WL "short" dipole figure 8 pattern broadside to wire 40M .70 WL "long" dipole figure 8 pattern broadside to wire 30M 2X .5 WL Two Half waves in phase - figure 8 pattern 50 degrees wide broadside to wire 20M 3/2 WL current fed LW - 6 lobes - 4main lobes approx 35* to wire 2 minor lobes broadside to wire 17M 2X 1 WL voltage fed LW's - 4 lobes approx 40* to wire 15M 2X 1.1 WL voltage fed LW's - 4 major lobes, possible minor (this is my "intuitive analysis...check w/modeling program) 12M 5/2 WL current fed LW - 10 lobes - 4 main lobes approx 30* from wire 10M 2X 3/2 WL voltage fed LW - 6 lobes - 4 main lobes approx 35* to wire 2 minor lobes broadside to wire de Tom N4KG ............................
