A piece of 1940s aircraft history may be just a few months away from flight.

The E-6B’s missions often involve deploying one of its two trailing wire antennas, which can extend up to five miles (or eight kilometers) in length. These antennas allow the aircraft to send ...

Abstract: This communication proposes an ultrawideband (UWB) H-plane monopulse log-periodic antenna designed for UAV applications in jamming signal detection. The main radiators are two log-periodic ...

When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna. These antennas usually are in a horizontal configuration up on a high tower.

As shown in Figure 4 of the FETCH antenna design, the cross-dipole log-periodic antenna transmits and receives two polarizations, linearly in two perpendicular directions. The plane of polarization ..

This antenna is a broadband antenna that can be used for public safety as well as cellular. It makes an ideal solution for a donor antenna for a DAS system. Comprod In-building system antennas are ...
