INNOV Log Periodic
100-1300 MHz 22ele Log Periodic Beam
Part number: Z08564-0117
130-LOG-1300 - 130MHz to 1300MHz Log Periodic Array (LPDA) is a 50Ω direct fed Directional wide band antenna for receiving and transmitting purposes. This antenna can be mounted horizontally or vertically with an optional mount.
As with all InnovAntennas products, only the highest quality materials are used including aerospace grade aluminium and marine grade (A4) stainless steel.
The 130-LOG-1300 uses a twin-boom arrangement as a feed line as well as a dipole support. The feedlines are fixed in spacing, it has very wide bandwidth with excellent Front to Back (F/B) as a result of the inclusion of parasitic reflectors and directors at either end of the antenna. 1/2'' (12.7mm), 3/8'' (9.525mm) and 1/4'' (6.35mm) elements are used to ensure maximum gain and bandwidth is achieved across the whole working range. the boom is made from twin thick-wall 3/4'' suqare tubes for a super rigid construction with twin U-clamps at the rear.
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 130-LOG-1300 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.
