Technical description 5LPDA8
The 5LPDA8 is a log-periodic (LogPer) antenna with 8 elements. The
system of the LogPer antenna differs from the classic design of a Yagi
in that this antenna has a uniform gain over the entire bandwidth and is
therefore not only usable on the amateur radio bands with good SWR. On
the other hand, the gain is somewhat smaller than with a Yagi of the
The 5LPDA8 uses 8 elements on a 6m boom. The feed is at the front of the shortest element. There, a balun is mounted on the boom, which is designed for a maximum transmit power of 5 kW. The average gain over ground is approx. 14 dBi. A solid mast clamp for masts up to 50mm diameter is included.
Application description 5LPDA8
A LogPer antenna is ideally suited for commercial radio services looking
for an antenna that can be used over a wide frequency range. The SWR is
1.5:1 or better in the specified range. This allows the LPDA8 to be
used at high power on all frequencies from 13.5 to 32 MHz. The gain and
the good directivity make this antenna also very interesting for
ambitious shortwave listeners. Due to the large bandwidth and the even
gain, band monitoring over many MHz with a suitable SDR receiver is an
ideal application for this antenna. Another advantage is that only one
cable is needed for all bands.

EAntenna was founded by Rodrigo (EA7JX) with the aim of building high performance shortwave and VHF/UHF antennas that meet very high quality standards while remaining affordable. WiMo took over EAntenna in 2017, the production was moved to Herxheim, Rod moved with his family and still provides good quality - now at WiMo.
