100MHz to 610MHz Log Periodic Array

InnovAntennas design and build Log Periodic Arrays for any bandwidth and for any purpose. Our LPDA's can be designed and built for your specific needs to ensure the absolute best performance can be acheived.

100-LOG-610 - 100MHz to 610MHz Log Periodic Array (LPDA) is a 50Ω direct fed Directional wide band antenna for receiving and transmitting purposes. This antenna can be mounted vertically or horizontally.

As with all InnovAntennas products, only the highest quality materials are used including aerospace grade aluminium and marine grade (A4) stainless steel.

The 100-LOG-610 uses a twin-boom arrangement as a feed line as well as a dipole support. the feedlines are tapered in spacing to remove impedance spikes across its very wide bandwidth which are common in some badly designed LPDA's. 1/2'' diameter (12.7mm) elements are used to ensure maximum gain and bandwidth is acheived along with Front to Back ratio (F/B).

Often, LPDA's are designed with a 200Ω feed point which ensures bandwidth. However, this results in the need for a 4:1 transforming balun which both reduces efficiency and limits any input power too. The 100-LOG-610 has been computer optimised to present a 50Ω feed point to allow for direct connection to ocax cable and thus, power limitations are largely removed.
