log periodic antenna vs yagi
Large log antennas can receive a very wide range of frequencies and in Australia most log periodic antennas will receive VHF and UHF frequencies. 3G 4G LTE5G Antenna.
In its use as a television antenna it was common to combine a log-periodic design for VHF with a Yagi for UHF with both halves being roughly equal in size.
. A Log has a wide bandwidth but generally lower gain than a Yagi. However a Yagi-Uda of the same boom length will provide higher. The Yagi-Uda antenna is mostly used for domestic purpose.
The advantage of an LPDA is it provides reasonably consistent performance across a large bandwidth. Find the right products that fits your budget and needs. By Jim Barrett KF2 Mon 09 Jul 2001 135413.

Are within a db of gain and the f-b is similar to a Yagi when the Yagi is tuned for reasonable forward gain. However for commercial purpose and to tune over a range of frequencies we need to have another antenna known as the Log. Ad At Your Doorstep Faster Than Ever.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas. This creates a large array without any gaps in it which can be most helpful in receiving a wide range of frequencies.
Conceptually Log-Periodic Antennas are similar to Yagi Antennas.
