What is the difference between antenna and antennae?
The transmitter or radio is the device that gives the "frequency" (for example "Ubiquiti XR7 radio") and the antenna is the device that irradiates that frequency. We have to consider that each type of antenna irradiates in a different way (for example dipole antennas that are omnidirectional or yagi antennas that are directive)
What is the definition of general liability classification code 99613?
Antenna repair, installation, maintenence.
How do radio waves carry energy?
Radio waves are energy. Electromagnetic energy to be exact. The amount of energy a radio wave has will depend on the amount of power the transmitter has, the amount of amplification, the quality of the cable connecting it to the antenna and finally the antenna. The amount of energy is usually measured in watts.
How do you cease a Rx path imbalance alarm in Bts?
1. Connect OMT to BTS and go to the RADIO VIEW after reading IDB. 2. Click on FAULT to check which Antenna shows the red indication. 3. If two antenna together shows the red indication , possible cause could be the Feeder cables swapped in between this both. 4. If Only one antenna shows red , check for the OD in ID connectors for possibly short due to moist or Water or durt. 5. Use the Site master for checking the VSWR in feeder cable. 6. After necessary actions been taken as suggested above, right click on antenna which was red indicated on OMT and set antenna supervision mesurement values SAMPLE = 100 and TIME = 5. then monitor for 10 to 15 min after reset given to perticular TRX. Wait and check if the alarm re-appears. Otherwise set the values as they were.
What is a Marconi antenna?
The term "Marconi antenna" usually refers to a two part antenna consisting of a vertical portion and a "reflective" or "ground" portion. When constructed properly, it is very similar to a vertically oriented dipole, in that one element is "up" and the other "down". The reflective portion is not always a physical element, but often either natural earth ground (where the soil conductivity is sufficient) or ground "radials" - a set of wires along or just beneath the ground that act as the reflective portion. A Marconi antenna is an omni-directional (same transmit/receive in all directions) antenna that has good long distance characteristics on HF (high frequency) and MW (medium wave, or AM) frequencies. A Marconi is typically built with a 1/4 wavelength vertical element, and similar length radial(s). For example, the full wavelength for 7MHz is about 133ft. A 1/4 wavelength vertical element (and each radial) would therefore be about 33.5ft. Most AM broadcast stations use some variation of a Marconi antenna. Since an AM station at 1050 on an AM dial is equal to 1.050MHz and therefore a wavelength of over 990ft, a 1/4 wavelength vertical element would be almost 223ft for that station! The antenna was originally made using telescopic fiber glass tubes and then covered with a copper film to make them look electrically like a huge copper tube. The antenna was made by a company located in London called Bantex Antennas. This company shut down and the team of engineer was take over and built a new company called Renair Antennae Ltd, they carried manufacturing these antennas for some years. These antennas were ordered from Marconi to be mount overseas mainly. They were real big monsters!
Is antenna inductive or capacitive?
An antenna can exhibit both inductive and capacitive properties, depending on its design and operating frequency. Generally, at resonance, an antenna behaves predominantly as a resistive load, while it may display inductive characteristics at lower frequencies and capacitive characteristics at higher frequencies. The balance between these properties is crucial for optimizing antenna performance and matching its impedance to that of the transmission line.
Why you are using capacitive hat in short antennas?
Capacitive hats are used to alter the distribution of the current on a short antenna so that the antenna current is not concentrated near the ground. A whip or short antenna can be modeled as a series of LC circuits in which the capacitance per unit length is highest near the base and the inductance per unit length is highest near the top. A capacitive hat simply adds capacitance to the antenna. It basically makes the antenna seem longer, but maximum current is still at the base.The reason why you'd want to make your short antenna longer, is to obtain the antenna's resonance frequency. The length required to do this is a quarter or a half of the wavelength of the radio wave that it's receiving. At resonance, the electrical resistance of the antenna drastically drops, which effectively increases the Q factor, or quality factor, of the resultant output signal. The term Q factor is simply a measurement of how good the clarity and stability of the output signal is, the higher the better when dealing with radios and televisions.Of course, instead of using a capacitive hat on your antenna, you could always physically lengthen the antenna itself. However, considering that commonly-used radio waves can be up to 10 m (33 ft) long, your antenna would have to be about 8 feet long, which would make using your radio a bit awkward.
How do you check to see if your antenna is too short?
A short antenna causes higher than normal current to capacitive reactance and a long antenna causes higher than normal current to inductive reactance; a correct length antenna is free of reactance and appears as a resistance. Change the length of the antenna in small increments until you obtain the lowest (resistive) current.
Does closing the laptop affect the antenna?
I don't really get how you have an antenna on your laptop, but if you do, it does not effect it.
What is significance of imaginary part in inductor?
No inductor is perfect and has a capacitive and resistive component. As frequency increases, these components have more effect on the circuit operation. A capacitive component would be out of phase and be the imaginary value.
What is the effect of an inductive or capacitive load under no load conditions?
A load of any type,,,inductive or capacitive , would effect the circuit even if THOSE "loads" had no load on them. They would still have a load effect on the circuit they are connected to.Answer'Under no-load conditions' means that no load is connected to the supply. So your question doesn't make sense!
What is ringing effect of antenna?
The ringing effect of an antenna refers to the oscillatory response that occurs when an antenna is excited by a pulse or transient signal. This phenomenon results from the antenna's resonant properties and can lead to unwanted distortion in the received signal. The ringing can introduce additional frequencies and affect the overall bandwidth and performance of the antenna, making it crucial to design antennas that minimize this effect for clearer signal transmission and reception. Proper filtering and damping techniques can help mitigate the ringing effect in practical applications.
What effect do var's have on the power factor of the circuit?
VAr is reactive power, caused by either inductive or capacitive loads. The ideal power factor to have is 1, anything less than that is a loss on the network. The effect of VArs on the circuit though depends. If you have a load that is mainly inductive, then adding more inductive reactance will lower the power factor. However, if you introduce capacitive reactance this will increase the power factor, and the opposite is true if its a mainly capacitive circuit. So VArs will either increase or decrease the power factor depending on the load of the circuit. The ideal situation is to balance inductive reactance with capacitive reactance so they in effect cancel each other out and power factor is 1.
Why the load voltage increases when the load used is capacitive?
capacitive reaction
What was the effect on the input impedance of lowering the operating frequency?
The input impedance should increase slightly for the lower frequency, when using a capacitive circuit.
The capacitive reactance of a capacitor increase as?
The capacitive reactance of a capacitor increases as the frequency decreases.

An IPS capacitive touchscreen is a type of technology that is used on LCD's.
