The Ku band (Kurtz-under band) is fundamentally utilized for satellite communication, especially for altering, editing and broadcasting television. This band is split into numerous sections separated into topographical locales, as the ITU (International Telecommunication Union) decides.

The Ku band is a segment of the electromagnetic range in the microwave scope of frequencies running from 11.7 to 12.7GHz. (downlink frequencies) and 14 to 14.5GHz (uplink frequencies).

The most well-known Ku band advanced gathering organization is DVB (Main profile video formating) versus the studio profile computerized feature configuration or the all out Digicipher II 4DTV arrangement.

The main company to widely use the Ku Band for a large portion of its partner television broadcasting was NBC, in 1983.

The ITU Region 2 portions covering most of the Americas are somewhere around 11.7 and 12.2 GHz, with more than 21 FSS North American Ku-band satellites presently circling.

Each obliges a 0.8-m to 1.5-m radio wire and conveys twelve to twenty four transponders, of which 20 to 120 watts are used (per transponder) for clear gathering.

The 12.2 to 12.7 GHz portion of the Ku Band range is allotted to the broadcasting satellite service (BSS). These immediate show satellites commonly convey 16 to 32 transponders.

Each gives 27 MHz in transmission capacity and expends 100 to 240 watts every, gathering recipient radio wires down to 450 mm (18 inches ).

The ITU Region 1 fragments of the Ku range speak to Africa and Europe. (11.45 to 11.7 GHz band extent and 12.5 to 12.75 GHz band reach are saved for the settled satellite administration (FSS), with the uplink recurrence running somewhere around 14.0 and 14.5 GHz).

Ku Band Difficulties

At the point when frequencies higher than 10 GHz are transmitted and got in an overwhelming rain fall territory, a noticed corruption happens, because of the issues brought on by and corresponding to the measure of rain fall (ordinarily referred to as known as "rain fade correspondence").

This issue can be battled, on the other hand, by conveying a fitting connection spending plan procedure when outlining the satellite system and distributing a higher force utilization to overcome downpour blur misfortune. Regarding end-viewer TV gathering, it takes overwhelming rainfalls in abundance of 100 mm for every hour to have a recognizable impact.

The Ku band's higher recurrence range is especially powerless to flag corruption, significantly more so than C band satellite recurrence range, however the Ku band is less helpless against downpour blur than the Ka band recurrence range.

A comparable phenomena called "snow blur" (when snow amassing essentially changes the dish's point of convergence) can likewise happen amid Winter Season.

Additionally, the Ku band satellites ordinarily require significantly more energy to transmit than the C band satellites. Be that as it may, both Ku and Ka band satellite dishes are littler (shifting in size from 2′ to 5′ in measurement.)

Ku Band Satellite Service Downlink Usage Frequency Range

-The Ku band downlink utilizes frequencies somewhere around 11.7 and 12.7GHz.

-The Ku band downlink frequencies are further subdivided by appointed utilization:

Ku Band Usage Downlink

-Settled Satellite Service 11.7 – 12.2GHz

-Show Satellite Service 12.2 – 12.7GHz

Administrations that can be found on the Ku-band incorporate instructive systems, business systems, sports backhauls, video chats, versatile news truck nourishes, global programming, different SCPC (Single Channel Per Carrier) transmissions of simple sound, and additionally FM sound administrations.

On the off chance that the client as of now has an operational C-band framework set up, he/she can retrofit it to acknowledge Ku band frequencies.

Keeping in mind the end goal to do as such, clients need to get a Ku-band LNB, a C/Ku band bolster hon, in addition to some sweet talk link for the Ku-band LNB.

Concerning the wheedle link suggested, RG-6 is ideal for low misfortune in the 950-1450 recurrence range, which is the thing that Ku-band LNB forms. Be that as it may, if RG-59 is the main feasible choice, it will work when absolutely necessary.

Ku Band Satellite Dish Antenna Compatibility

In accordance that the client has a strong dish, he/she should have no issue changing over from C band to Ku band.

On the other hand, with a lattice dish, if the "gaps" in the cross section are more prominent than a quarter crawl, the shots of calculability are not in the client's support because of the way that his/her dish won't reflect Ku-band flags appropriately.

In this way, the client could emphatically consider moving up to either a strong dish or a lattice dish in which the opening size is under 1/4." Ideally, the dish ought to be 1 piece (or if nothing else not very many pieces). A 4 area dish is more ideal than a 8 segment dish.

The less the areas, the more precise the parabola shape is and the more troublesome it is for the dish to wind up twisted (the littler the quantity of creases the better). To the extent dish mounts go, the H2H (Horizon-to-Horizon) dish mount is more attractive than a polar mount.

This is because of the way that the Ku-band requests that the dish radio wire framework is all around focused on and ready to nearly take after the orbital bend, which the H2H mount does splendidly when contrasted with a polar mount. Additionally, remember that the client will be altering both the azimuth and rise, which can be a touch precarious every so often.

Significance of Satellite Antenna Dish Parabola

In this picture we see the Prodelin Satellite as a example.

The dish's illustrative shape is basic significance as war-page reasons signal debasement by means of mis-reflection, depleting considerably general overall system performance. Some tape and string is all that is needed to conduct a snappy war-page check.

Draw the string as tight as could be allowed, "north" to "south" over the dish face and edge to edge. Do likewise again with another bit of string, just "east" to "west" over the dish face at 90 degree edges. Verify that both strings are tight.

In the event that the strings meet up anyplace besides the center of the dish, then it has managed to be warped and should be bowed once again into legitimate parabola shape for ideal performance. On the off chance that they associate in the focal point of the dish, it is likely that the dish is not distorted.

Subsequently, utilize either the tri-backings or quad underpins as they will significantly help with keeping the Ku-band feed horn very steady, even in high winds.

When the button hook feed moves in the wind, Ku-band antenna reception can easily drop out. By putting guided wires on the button hook feed, the user will create the much needed support in the event that the user is unable to obtain a tri support or quad support.
