In radio engineering, an antenna or aerial is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment.An antenna is an array of conductors (elements), electrically connected to the receiver or transmitter. Antennas can be designed to transmit and receive radio waves in all horizontal directions equally (omnidirectional antennas), or preferentially in a particular direction (directional, or high-gain, or “beam” antennas). An antenna may include components not connected to the transmitter, parabolic reflectors, horns, or parasitic elements, which serve to direct the radio waves into a beam or other desired radiation pattern. Strong directivity and good efficiency when transmitting are hard to achieve with antennas with dimensions that are much smaller than a half wavelength.
The first antennas were built in 1888 by German physicist Heinrich Hertz in his pioneering experiments to prove the existence of waves predicted by the electromagnetic theory of James Clerk Maxwell. Hertz placed dipole antennas at the focal point of parabolic reflectors for both transmitting and receiving. Starting in 1895, Guglielmo Marconi began development of antennas practical for long-distance, wireless telegraphy, for which he received a Nobel Prize.
Pwede ko bang magamit yung antenna na yan as Signal Booster or Repeater? left over siya ng Globe tats na internet namin dati.

Ask lang mga sir. ano pinag kaiba ng anderson at 18dbi or 11dbi na antenna? sabe kase mas malakas daw sumagap ng signal ung 18dbi, same lang ba un ng anderson antenna? bbili kase ko e walang stock na 18dbi. ok lang kaya na anderson? thanks ng marame sa sasagot hehe.
Mga kaPhc, maitanong ko lang kung ano ang mas mainam na gamitin ko sa aking 936 para makakuha ako ng mataas na SINR at maabot ko ang mabilis na speed ng LTE connection?
Ano po kaya yung may problema yung dv ko o yung mimo antenna pag yung dalawang saksakan ng mimo po kasi nakasaksak connected no browse pag yung isang saksakan lang ng mimo nakasaksak nakaka browse siya
pahelp po pano kaya gagawin dun kapag dalawa yung antenna na nkasaksak connected no browse sya pero nung tinanggal ko yung isa nakakabrowse na po ano kaya problem nun?
Guys help naman regarding sa paghinang sa board para ifix yung outdoor antenna wala kasi kung connector.
Yung may hinang wire na black at hùbád andun na talaga yun nung binuksan ko si toy. Salamat
may tanong lang ako
sa 622 kasi may dalawang input ng antenna
pag pinagsabay ko ba ok lang?
at ma kakasagap parin ba ng signal ung internal antenna?
salamat po sa sagot
mga sir tulong nmn po ,mybro modem ko ngayun po bumili ako ng wimax antena ,kinabit ko sa modem ko working puno signal nia mga 1mons cguro na full signal.pero isang araw bigla nalang nawala signal nia ,pero pag nilalagay ko yung dati niyang antena na maliit my sgnal xa,ngayun bumuli ulit ako ng...
pulot ko lang din naman ito sa google :) workng naman kasi eh kaya share ko na lang..
1. use 2.0 usb extension nabibili po sa CDR-KING and make sure testingin muna bago bumili para hindi kayo magkaproblema.
2. UTP CAT5 which is white color wire and UTP CAT6 yung blue color wire. Pwede rin...
