VHF is the first band at which wavelengths are small enough that efficient transmitting antennas are short enough to mount on vehicles and handheld devices, a [[whip antenna|quarter wave whip antenna]] at VHF frequencies is 25&nbsp;cm to 2.5 meter (10 inches to 8 feet) long. So the VHF and UHF wavelengths are used for [[two-way radio]]s in vehicles, aircraft, and handheld [[transceiver]]s and [[walkie-talkie]]s. Portable radios usually use [[whip antenna|whips]] or [[rubber ducky antenna]]s, while base stations usually use larger fiberglass whips or [[collinear antenna array|collinear arrays]] of vertical dipoles.

For directional antennas, the [[Yagi-Uda antenna|Yagi antenna]] is the most widely used as a [[high gain antenna|high gain]] or "beam" antenna. For television reception, the Yagi is used, as well as the [[log-periodic antenna]] due to its wider bandwidth. [[Helical antenna|Helical]] and [[turnstile antenna]]s are used for [[satellite communication]] since they employ [[circular polarization]]. For even higher gain, multiple Yagis or helicals can be mounted together to make [[array antennas]]. Vertical [[collinear antenna array|collinear arrays]] of dipoles can be used to make high gain [[omnidirectional antenna]]s, in which more of the antenna's power is radiated in horizontal directions. Television and FM broadcasting stations use collinear arrays of specialized dipole antennas such as [[batwing antenna]]s.
