Most notable was deployment of a large Yagi antenna from NORsat-2 that will provide first-of-its-kind VHF Data Exchange (VDE) from space.
As can be seen from radiation pattern of Yagi antenna it's scattering into the back direction is very large.
Because a high S/N ratio was necessary for the reference signal, for the reference antenna a five-element Yagi antenna with a horizontal polarization characteristic was placed in a position making it possible to obtain a high S/N ratio.
A yagi-Uda array antenna also called simple yagi antenna. Which carries driven element composed of typically folded dipole or a dipole and its parasitic parameter known to be an reflector and based on many directors.
In Section 2, we introduce the traditional Yagi-Uda antenna first and then propose the bidirectional Yagi antenna. Section 3 shows the proposed stacked bidirectional antenna structure based on the bidirectional Yagi antenna.
The equipment used was a simple Yagi antenna manufactured with aluminium angle and copper pipe mounted on a wooden boom; suitable antennas can also be purchased for around 30 [pounds sterling].
The reconfigurable antenna proposed here is similar to microstrip Yagi antenna. As is shown in Fig.
Following release and for the next 4 days, we used a hand-held, three-element Yagi antenna and a radio-receiver (Model R2000; Advanced Telemetry Systems, inc., isanti, Minnesota) to locate lizards before dawn, while subjects were inside their nocturnal refuges.
Permanent stations are powered by a solar panel and car battery, and the data are transmitted to a base station by a Yagi antenna. The base station includes a receiving antenna connected to the local network and a laptop computer with an external hard drive for local backup.
