The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas. <br style="text-align: justify; color: rgb(0, 0, 0); text-transform: none; text-indent: 0px; letter-spacing: 0.25px; font-family: Mulish, sans-serif; font-size: 14px; font-style: normal; font-weight: 400; word-spacing: 0px; white-space: normal; box-sizing: border-box; orphans: 2; widows: 2; background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><span style="text-align: justify; color: rgb(0, 0, 0); text-transform: none; text-indent: 0px; letter-spacing: 0.25px; font-family: Mulish, sans-serif; font-size: 14px; font-style: normal; font-weight: 400; word-spacing: 0px; float: none; display: inline !important; white-space: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements. <br style="text-align: justify; color: rgb(0, 0, 0); text-transform: none; text-indent: 0px; letter-spacing: 0.25px; font-family: Mulish, sans-serif; font-size: 14px; font-style: normal; font-weight: 400; word-spacing: 0px; white-space: normal; box-sizing: border-box; orphans: 2; widows: 2; background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><span style="text-align: justify; color: rgb(0, 0, 0); text-transform: none; text-indent: 0px; letter-spacing: 0.25px; font-family: Mulish, sans-serif; font-size: 14px; font-style: normal; font-weight: 400; word-spacing: 0px; float: none; display: inline !important; white-space: normal; orphans: 2; widows: 2; background-color: rgb(255, 255, 255); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;">With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.
