Stacking
The antenna can be easily stacked for ap-
proximately 3 dB more gain each time the
number of yagi is doubled. Refer to Figure 4
for stacking and phasing harness cutting
information.
The two phasing lines coming from the two an-
tennas to the "T' connector can be any odd
multiple of one-quarter wavelength in the 75
ohm transmission line. See Figure 5.
NOTE: When phasing two antennas, the
Driven Element halves that are connected
directly to the phasing lines should be on the
same side of the array.
The feedline impedance is for 50 ohms (RG-
8/u). For detailed information on stacking
more than two yagis, please consult any
current Amateur Handbook.
