To make a seawater antenna, the current probe (an electrical coil roughly the size and shape of a large doughnut) is attached to a radio’s antenna jack.
The tower is designed to put the antenna at a maximum height on the spire.
That report indicated that there may be a hardware issue somewhere between the antenna and the amplifier.
As you can see from the radar data, there appears to be light precipitation within a 30-mile radius of the radar antenna.
Another oddity: When paddling through the water, a platypus keeps its eyes, ears and nostrils closed, and its duck-bill serves as an antenna, sensing the faint electric fields surrounding prey.
Parabolic reflector antenna
Pram provided with a radio, including antenna and loudspeaker, to keep the baby quiet.
Cephalic muscles may be divided into(a) cervical muscle(b)muscles of the mouthparts, and(c)muscles of the antenna.
Other ideas include building a detector to see if the spin of an atomic nucleus can be measured, or using the technique as an ultrasensitive antenna.
The entire length of the tower is equipped with a feeder (a coaxial wave-guide) through which signals are transmitted from the transmitter to the antenna on the spire.
How to improve the test precision of antenna gain is the key point for antenna gain test in the outfield.
For the two operating frequencies of the proposed antenna, the same polarization planes and broadside radiation patterns are obtained.
The near field test for the antenna array and the outfield test for whole radar system are finished. The target in the airport can be observed.
reclining radio antenna
An antenna was not found inside, but a balloon with freon was there.
Previously the problem was that a wearable antenna would sometimes touch a person's skin, or the wearer would walk into a building and turn away from the source of the strongest signal.
They erected a television antenna on the roof.
A new type of broadband printed twin dipole antenna is proposed in this paper. Corresponding feed structure of broadside coupled parallel line is also designed.
The antenna problems were a rare glitch in Apple's rollout for a new product.
Horn parabolic reflector antenna
A large disc-shaped rectifying antenna attached to the fuselage harvested the microwave energy, turning it into direct current to power an electric motor attached to the plane's propeller.
Using a directional antenna, the device shoots data to a receiving antenna as far as 60 miles away.
All data collected by the spacecraft will get beamed back to Earth using a radio transmitter and an 83-inch diameter radio antenna.
But at the last minute on that night, a bearing in the antenna failed, rendering it nearly useless.
