A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves to the receiver in its focal point. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity. It functions similarly to a searchlight or flashlight reflector to direct radio waves in a narrow beam, or receive radio waves from one particular direction only. Parabolic antennas have some of the highest gains, meaning that they can produce the narrowest beamwidths, of any antenna type. In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the wavelength of the radio waves used, so parabolic antennas are used in the high frequency part of the radio spectrum, at UHF and microwave (SHF) frequencies, at which the wavelengths are small enough that conveniently-sized reflectors can be used.
Parabolic antennas are used as high-gain antennas for point-to-point communications, in applications such as microwave relay links that carry telephone and television signals between nearby cities, wireless WAN/LAN links for data communications, satellite communications and spacecraft communication antennas. They are also used in radio telescopes.
The other large use of parabolic antennas is for radar antennas, in which there is a need to transmit a narrow beam of radio waves to locate objects like ships, airplanes, and guided missiles, and often for weather detection. With the advent of home satellite television receivers, parabolic antennas have become a common feature of the landscapes of modern countries.The parabolic antenna was invented by German physicist Heinrich Hertz during his discovery of radio waves in 1887. He used cylindrical parabolic reflectors with spark-excited dipole antennas at their focus for both transmitting and receiving during his historic experiments.
Good day po, bakit po kaya parang walang pagbabago sa speed nung nagkabit ako ng grid parabolic antenna, gamit ko po ay LTE openline router, TP-link TL-MR100. Smart sim po ang naka insert. Secondhand po ang antenna at sabi nung previous owner working naman daw po yun. Pwede po kayang hindi sila...
Boss / Master sa mga nag i install ng mga parabolic antenna need pa ba ng permit. Pinapa alam ba muna sa baranggay hall or sa mga network providers na nag install ng cell towers?
Ano po magandang parabolic antenna para sa modem na greenpacket d2 or 936 para sa dead spot as in zero signal kahit cp wala signal. meron nag offer pero mahal. balak ko sana ako nalang magkabit.
May gumagamit ba dito ng parabolic antenna 2*30dbi
tas naka unlidata 299 sa smart/tnt ..
tanong lang if nakaranas na kayo ng blocking sa smart
tas ganyan antenna at promo na gamit nyo?
Meron po akong outdoor antenna na hybrid mimo antenna 36dbi pero ito po ung mga nakukuha kong stats
ung SINR nag lalaro sa 4-13 dbm, nabasa ko dito na dapat mas mataas sa 12 dbm ang SINR
Also naka smart corpo ako, baka kasi hindi ko magamit sa full potential ung sim kaya na ask ko if need ko pa...
Mga zer, ano po magandang e partner na modem sa parabolic?,
Since deadspot lugar namin malayo ang kinabitan ng parabolic at modem sa bahay namin at ginamitan lng to ng fiber wire para ma tranfer ang internet through wifi router, D ko alam kung sa modem ba o sa lugar bakit humihina internet...
200Kbps speed sa umaga (11AM-11PM) at 12Mbps sa gabi(11PM-11AM) at magdamag
naglagay ako ng satelite dish sa bubong may poste pa mga 8 meters cguro at modem ko OD235
meaning ba neto congested ang network dito sa area ko?
balak ko sana bumili ng parabolic antenna, kaso ayaw ko masayang mahal...
Good evening mga master
ask ko lang po if there is a way na mapagana or ma detect yung parabolic antenna ko (24db x2) sa ZLT S10G.
working si parabolic sa 936 ko, sa ZLT S10G lang ayaw.
may isa din akong mimo antenna, globe mimo 18db, working sa dalawang router ko.
sana may makatulong.
thanks
Need help po magdecide kung bibilin ko ang antenna nato (nasa baba po yung pic) may kamahalan at yan na ata max/pinakamaganda ni skywave
Setup: B525s at 18 dbi ni globe= 2Mb/s DL at 3Mb/s UP
May pag-asa pa bang bumilis yan kung bibilhin ko yung parabolic antenna na nasa pic.
Note: Alam kong...
Mga sir tanong lang po if malupet na po ito sa speed? Area ko nasa Cebu city.
Bibili sana ako nito. Salamat po in advance if may nakapag try na. Godbless
B525s-6a
DL speed: up to 300mbps
UL speed: up to 159mbps
Mga boss ano po suggestion niyo na magangdang parabolic antenna na mag mamatch sa freq ng Modem 936 version 21.327.01.00.1394??? Pa suggest po salamat ^_^
