Log Periodic Dipole Array 13 element 10MHz - 54MHz LPDA
A Super Wide Band, High Performance Log Periodic Dipole Array - 10MHz to 54MHz inclusive
All InnovAntennas LPDA’s are design using the very latest computer optimisation techniques and are largely designed and built to order although examples such as this Dense Element Log Periodic Dipole Array (DELPA) are displayed and advertised in order to give an idea of our capabilities and pricing.
This antenna was specifically designed for a requirement at Broadcast Central Europe and the example photos display the DELPA-13 installed at the BCE broadcast centre.
The DELPA-13 has 11 elements placed above a 11.5m long 3’’ diameter boom of which all elements are insulated. The feed point is 200Ohm and is fitted with a 20KW 4:1 balun. Feed-line between the elements is hard-drawn copper wire which is silver plated and spaced in order to produce a 300Ohm balanced-line feed.
The DELPA-13 provides excellent, consistent results for the frequency range it covers and the relatively limited number of elements. For more details on this or other Log Periodic developments, contact as directly now on our sales lines or via Email sales ‘at’ innovantennas .com
Some of the Mechanical design benefits include:
- Marine grade Stainless Steel Fittings*
- Integrated feed-line/boom for maximum efficiency, minimum wind-load
- Sliver-plated balanced line feed
- Mill finished for highest levels of accuracy and performance
If you are looking for the best of the best from both a performance and mechanical construction perspective then look no further, you have come to the right place!
'It performs like nothing I've ever seen. In the USA, we have some 3000 watt TV stations that broadcast FM audio on 87.75. There are 3 of them within 375 miles of me and with this antenna, I have heard them all! The gain and directivity far exceed the APS-13 that I took down. Somehow the word "amazing" doesn't do this justice.'

This antenna has all elements made from 1/2 inch aluminium thick wall tube. The parasitic elements are also 1/2 inch. All elements are electrically connected to the boom held in place by marine grade stainless steel components.
The boom is 3/4'' inch square (19.05mm) which is in 3 sections. two sections of boom form the feedline and antenna element support, the third section provides a boom support truss.
If you want an antenna to last and perform in all weathers without SWR or bandwidth shifting, this is it.
Manufactured the right way, not the cheapest way!
