InnovAntennas 10 Element HF Band Optimized Log Periodic Antenna is a super wideband, high performance beam that covers the frequency range of 14 to 30 MHz. The advantage of this antenna type is the extreme broadband performance with an even gain curve without dips. This makes this antenna suitable not only for amateur radio, but also for commercial services and for demanding SWLs.
Through careful calculations and practical optimization, the spacing and lengths of the elements have been chosen to favor the amateur radio bands 20/17/15/12 and 10 meters, creating the Band Optimized Log Periodic Antenna, hence the nam

This makes this antenna suitable not only for amateur radio, but also for commercial services and for demanding SWLs.
Through careful calculations and practical optimization, the spacing and lengths of the elements have been chosen to favor the amateur radio bands 20/17/15/12 and 10 meters, creating the Band Optimized Log Periodic Antenna, hence the name "BOLPA". Hundreds of hours optimizing both SWR and performance within the Amateur bands resulted in exceptional mono-band style performance for InnovAntennas BOLPA-10. This antenna provides a uniform gain of approximately 7 dBi over the entire frequency range and a front-to-back ratio over 20 dB on all but 12 meters with an SWR of mostly better than 1.5:1. The boom length of 25.3 ft. (7.7m) is relatively short for an antenna of this type. Since only one 50 ohm feed line is necessary, this broadband antenna is especially well suited for use with modern SDR transceivers that are able to receive on several HF bands simultaneously.
This LPDA's double boom is made of 1.75 in. (44 mm) square aluminum, each supporting the alternately arranged elements and provides the support for the bracing in the middle. Both boom tubes serve as feed lines for high power operations on any band with no tuning adjustments necessary. A common mode choke or balun may be used. High quality aircraft grade aluminum, as well as stainless steel parts, means the BOLPA-10 is also designed for adverse weather and high wind speeds of up to 99 mph (160 kph).
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
* Mill finished for highest levels of accuracy and performance
* First-of-kind "Band Optimized" LPDAs by G0KSC
InnovAntennas BOLPA-10 technical performance data:
* Gain: 6.9 to 7.5 dBi (4.75 to 5.4 dBd)
* Gain at 33 ft. (10m) above ground at 14.150 MHz: 11.56 dBi (including ground gain)
* Typical F/B: Over 20 dB
* Power rating: 5,000 watts (further limited by feedline and connectors)
* Feed impedance: 50 ohm, stud connections
* Boom length: 25.3 ft. (7.7 m)
* Longest element: 42.6 ft. (13 m)
