| Mar 25, 2014 at 8:32 | comment | added | user | @Optionparty I believe you are reading the question wrong. It's not "multiple wavelengths" as in "works equally well on a number of different frequencies", but rather "multiple wavelengths" as in "the physical size of the antenna is several wavelengths at the operating frequency". This interpretation is supported by the accepted answer being what it is. Is that the reason for your original comment? | |

I've seen plenty of similar constructions. | |

Better title and tags; copy-editing

A high-gain antenna is much more practical at 23 cm than at 20 meters simply because the physical dimensions are smaller. Stacked dipoles can provide you with vertical gain and horizontal omnidirectionality; this is reasonably practical on two meters, and very practical on 70 cm and up. | |
