Radio frequency grounds passes

Low frequency radio antenna arrays

SHF Super high frequency UHF Ultra high frequency

This is a radio frequency ID system.

Radio frequency (RF) is a rate of oscillation in the range of around to , which corresponds to the frequency of radio waves, and the alternating currents which carry radio signals.

Radio frequency engineering is a subset of electrical engineering that deals with devices that are designed to operate in the radio frequency (RF) spectrum.

VHF Very high frequency

Early next morning, Mayday calls were jamming the emergency radio frequency.

High Frequency Network 1 750 000

High frequency light waves look violet,

The need for a high frequency radio system for district coverage will be assessed and established by 1 June 2006 if found to be necessary.

A low frequency wave doesn't have nearly as much umph as a high frequency one.

Wireless communication, radio frequency power transmission and solar cells are expected in future developments.

Watson was in fact listening to very low frequency radio emissions caused by nature.

The new radar also includes a new cooling system and Radio Frequency Tunable Filters (RFTF).

Low frequency radio arrays can be deployed at two levels option one is low frequency monitoring of solar radio bursts with single dipoles and option two is 8 16 element arrays for monitoring of the whole sky.

We can do high frequency monitoring to get objective data.

Opportunities are being explored to install a low frequency radio telescope at the Gauribidanur radio telescope site in India to work in conjunction with CALLISTO in Ooty.

The spectrometer is well suited for solar low frequency radio observations pertinent for space weather research and applications.

Radio frequencies with a very long wavelength (very low frequency or VLF) bounce back off the ionosphere allowing radio communication over the horizon and around the curved Earth.

Since that period, however, clandestine radio broadcasts have sought to disrupt Radio Maanta and other Somali broadcasts, by broadcasting at the same time and on the same frequency.

The Group did not consider the installation of radio frequency grounds passes to be a priority at the moment.

The Philippine tarsier, has a high frequency limit of auditory sensitivity of approximately 91 kHz with a dominant frequency of 70 kHz.

On matters related to navigation policy and the radio frequency spectrum, ICAO coordinates its work with IMO and ITU, respectively.

The system, based on very high frequency radio, will enable users to ascertain the name, position, course, speed, draught and cargo of every ship of more than 300 gross tons sailing in the Baltic Sea.

Scintillation affects radio signals up to a few GHz frequency and seriously degrades and disrupts satellite based navigation and communication systems.

During the reporting period, Radio Okapi launched additional programming on its short wave frequency devoted to voter education regarding the electoral process.

It shares the Government concern that the level and frequency of such crimes remain extremely high.

That coil is connected to an R.F. amplifier that creates a high frequency oscillating magnetic field.

Each radio programme deals with a subject of high priority to African women.

As discussed in the progress report (IDB.30 11 PBC.21 11, para. 8), these relate to windows replacement and radio frequency grounds passes.

223. A high frequency (HF) network is also in operation to interconnect the theatre, sector and battalion headquarters with Bosnia and Herzegovina Command, the rear logistics base at Pleso and theatre headquarters using HF radio base stations established at battalion headquarters.

In Khartoum, UNMIS Radio is ready to go on the air, but the Government has not allocated a frequency and is seeking assurances that the content of all radio broadcasts will be linked to the UNMIS mandate.

When we receive this high frequency energy, it allows this system to vibrate at its highest potential.

Up high, these variable lines indicate increasing noise in this frequency range from higher wind and wave.

Unfortunately, the station's role and independence to broadcast on an FM frequency has become the subject of a dispute with the Ivorian Radio and Television.

Because they're so picky, the fussy high frequency waves lose out and most of the energy is carried away in lower frequency packets that are willing to take an equal share.

The installation of an access control system consisting of radio frequency equipment to read grounds passes is estimated by UNOV at 0.8 million, or 0.75 million.
