InnovAntennas 13 Element HF Log Periodic Dipole Arrays provide super wide-band, high performance from 10 to 54 MHz. InnovAntennas LPDA's are designed using the very latest computer optimization techniques such as Dense Element Log Periodic Dipole Array (DELPA). This type of antenna was designed with specifications for a broadcasting center. Example photos display the DELPA-13 installed at the broadcast center. If you are looking for the best of the best from both a performance and mechanical construction perspective, then look no further than InnovAntennas LPDA! You have come to the right place!

Some of InnovAntennas HF Log Periodic Dipole Array mechanical design benefits include:

• Marine grade Stainless Steel hardware (wherever possible)
• Integrated feed-line/boom for maximum efficiency, minimum wind-load
• Silver-plated balanced line feed
• Mill finished for highest levels of accuracy and performance

InnovAntennas DELPA-13

The DELPA-13 has 13 elements placed above the 37.73 ft. (11.5 m) by 3 in. (76 mm) square boom, from which all elements are insulated. The feed point is 200 Ohm and includes a 20 kW 4:1 balun. Feed-line between the elements is silver plated hard-drawn copper wire spaced to produce a 300 Ohm balanced-line feed. The DELPA-13 provides excellent, consistent results for the frequency range it covers with a relatively limited number of elements.
