Eureka, good catch. I have read that so many times and not noticed that!
A YA-1713 is a highband VHF only antenna.
If you wanted to put up a separate low band (ch2-6) antenna you would need a Winegard YA 1026 10 Element Lo-band Yagi Antenna to match the level of gain of the other two, but that is BIG antenna. You could use a AntennaCraft Y5-2-6 Lowband-Broadband VHF Yagi, with half the boom and probably in the range of 2 to 3
db less gain, despite the manufactures specs of only 1
db less than the YA-1026.
However stacking all three in my opinion is not a good idea or at least non-trivial.
First just the presence of three antenna being above the guy wires is a prescription for wind damage.
If the low band is on the bottom and high band in the middle of the stack, if you really wanted to take antenna aperture of the low band into effect, it would need to be 12 ft below the high band. This is theory and in reality the small area disrupted at the top of the low bands aperture caused by the highband yagi, the spacing can be reduced to 5 to 6 ft with no effect on the high band and very little damage to the low band's pattern.
All that theory aside.
I believe if a person has channels in all three bands, a combo antenna wins due to the simple fact of the construction difficulties with stacking 3 antennas.
