ROTATABLE LOOP/DIPOLE VERT LOOP/DIPOLE BEVERAGE

10 DEG -13 -5 -9

20 DEG -8 -3 -7

30 DEG -5 -3.3 -6.5

40 DEG -2.4 -4 -8

50 DEG -1.8 -6 -13

60 DEG -0.8 -8 -30

70 DEG -0.6 -11

80 DEG -0.0 -15

90 DEG -0.0

NOTE OUTSIDE CURVE = ZERO
0dB = 2.15dBi Frequency 1.9 MHz

All above perfect ground
Rotatable dipole @ 65 feet
Vert Dipole 2 feet above ground
Beverage 10 feet above ground
Note that Beverage has beam pattern with good f/b
Dipoles basically circular pattern and good for transmit and receive
