log periodic antenna vs yagi
Yagi-Uda will give higher gain at its optimal frequency. A yagi tuned for max f-b can exceed 45db over a narrow range but will lose a db in forward gain thus back to par with the log.

So an adjustable Yagi-Uda should provide higher gain than a comparable LPDA.
. Which of the following is an advantage of a log periodic antenna. It all depends on what you want from your antenna. As against in log periodic dipole array the increase in the number of connected elements improves the frequency response or bandwidth that is offered by the system.
Heres where it gets confusing. Working of Log Periodic Antenna. Why is an LPDA a better option for 2G 3G 4G an.
Our Log Periodic antennas offer up to 11 dBi gain between 1710 and 6000 MHz and 10 dBi gain between 600 MHz and 900 MHz. Its up to you to decide what you want from the antenna. If an inexperienced TV antenna installer doesnt know which signal is available in a fringe area he or she can use a log periodic antenna to receive either one.
Log-periodic will have lower gain across a wide range of frequencies. Save Reply D Dave Loudin Registered Joined Jun 25 2009. The advantage of an LPDA is it provides reasonably consistent performance across a large bandwidth.
In a true Yagi antenna there is usually a small number of elements doing the work while in a log periodic antenna every one of the horizontal elements you see is actually receiving elements. Free shipping on qualified orders. 3G 4G LTE5G Antenna.
1 pc UWB Ultra Wide Band 135GHz-95GHz Log-Periodic Directional RF Antenna with N Female Connector. However remember that in 99 of cases the correct yagi antenna will receive a far better signal than a log periodic antenna for both signal strength and signal quality. Import quality log periodic vs yagi supplied by experienced manufacturing companies at Global Sources.
Choose From A Wide Selection Of Home Office Items. There is always a compromise that MUST be made. However a Yagi-Uda of the same boom length will provide higher gain using fewer elements but a narrow bandwidth.

The 2019-2023 General License question pools asks about the advantage of a log periodic antenna. Log Periodic Directional Yagi Antenna 15dbi Gain for 3G 4G LTE XLTE AWS IDEN PCS 698MHz-2700MHz Wide Band Full Band. Read customer reviews find best sellers.
The Log Periodic array consists of a uniformly tapered array of many elements. A Yagi tuned for MAX forward gain has a f-b of maybe 15db so a log may have a better f-b in that case. Free easy returns on millions of items.
A multi band yagi covers several bands usually 3 or 4 with limited bandwidth on each one. We have seen that the addition of elements in case of Yagi-Uda antenna provides an increase in gain and directivity. Polarization diversity The log periodic antenna is a specialized antenna with unique.
A Log has a wide bandwidth but generally lower gain than a Yagi. The lengths of the elements and the spacing between them decrease by a constant ratio as you move down the array and. Of similar boom length Logs get a bad rap sometimes.
Dr Andre Fourie explains what the difference between a YAGI and LPDA Log Periodic Dipole Array antenna is. Log periodics are generally quite large understatement and. The Yagi has High gain levels but relatively narrow bandwidth.
I thought the same thing before I looked into them closely. TV Antenna With Megnetic Base. This creates a large array without any gaps in it which can be most helpful in receiving a wide range of frequencies.
