If will see standing wave comparing can express be with the viewpoint of power.
Multiple of wavelengh of length of theory of antenna of dot of frequency of standing wave comparing is actual length differs quantity.
In mobile system,ask standing wave comparing is less than commonly 1.5, but the VSWR in applying actually should is less than 1.2.
The main parameter of token antenna function has direction to pursue, gain, input impedance,standing wave comparing, polarization mode.
Standing wave comparing: It is the reciprocal of travelling wave coefficient, its value is in 1 arrive between infinity.
But the difference that provides quality because of horniness model, cover after going up in aerial,may affect standing wave comparing, try to notice in application please.
Standing wave comparing will be very right now tall, that is to say, major power reflexes carriage return stage, radiate of very few power comes out.
This one phenomenon is compared with standing wave commonly(SWR) description,standing wave comparing is more adjacent 1 better,wave of 1 delegates reflex is 0.
Standing wave comparing is 1, express to match completely; Standing wave expresses total reflection than be infinity, break completely match.
The effect stand or fall of shortwave communication system, basically depend on the bandwidth of the stand or fall of a function of use broadcasting station and antenna, gain,standing wave comparing, directional wait for an element.
If will see standing wave comparing can express be with the viewpoint of power/ of Pr of of Po+ of of SWR(Pr of of Po-) Po: Enter the power Pr of aerial system: Ji of the low Xi that remove porcelain blows You Yu You grave Course operation S.
In aerial system, aerial and equipment deserve to receive good the parameter that we often call standing wave to compare with is measured to its,it is when standing wave comparing of 1 when, state this antenna system matchs good without reflection.
Remind finally a bit, the stand orfall of aerial cannot sheet sees standing wave comparing, the reason that everybody has blind faith in standing wave to compare so now is very simple, it is good petty gain, good to be expressed because of standing wave namely buy.
This antenna uses aluminium alloy and coaxial cable structure, weight is light, tear open easily outfit, have aerial gain it is tall, good to match performance, frequency bandwidth,standing wave comparing is low and blast off goodly with receive performance.
In aerial system, aerial and equipment deserve to receive good the parameter that we often call standing wave to compare with is measured to its,it is when standing wave comparing of 1 when, state this antenna system matchs good without reflection, such number is meant greatly more match a state to jump over difference, the existence in the system jumps over big reflection wave. .
Above all, receive on SWR watch, change the connection that increases feeling coil take a percentage of a deal at the same time, the standing wave that measures aerial at the same time is compared, be like the word with regular ground contact,standing wave comparing should be OK drop be worth to low-down.
Horizontal idol extremely when aerial is being adjusted, can leave the two end of aerial component 30 centimeter very first the left and right sides is perpendicular dangerous, the attention side another sees standing wave compare a list, cut off 5 centimeter of 3~ to control length at the same time,arrive all the time till lowest of standing wave comparing, this is the simplest adjustment one of methods.
When use standing wave is compared than expressing the standing wave that measures aerial, want to compare standing wave the watch to because the transmission loss of transmission line can make a standing wave that the quantity comes outlesserer than numerical value, near aerial end as far as possible turn" joy into" of standing wave comparing for example originally the standing wave of aerial is 10% than reflexing power per cent for 1.92.
Standing wave compares(SWR) the computational formula that S is worth is next graphs.
The measurement technique that aerial standing wave compares.
Standing wave compares(S): In complete frequency paragraph inside, the standing wave that carries line of the make a present of that measure a nature on the head in microwave frame is more than than answering 1.15.
Most the stand or fall that after warns a bit antenna cannot sheet sees standing wave compare the reason that everybody has blind faith in standing wave to compare so now to compare a watch very simply to buy the means that gets me to say to be not compared because of aerial standing wave everywhere because of standing wave very low feel all OK be pleased with oneself studies more the other of aerial.
In addition current major standing wave compares a list is to use inductive means to compare signal response to standing wave inside the watch measure circuit to be able to blast off at the same time when measure so at the same time this does not meet the switch that switch standing wave compares a watch to go up attaint radio if machine is a bit more careful.
Afore-mentioned standing wave is compared is lowermost standing wave is compared-- visible, I design the antenna in 7mhz resonance this pair(as a result of the heart when debugging too urgent, be cut too much, the result is in 8mhz is syntonic) be in respectively" of wavelengh times odder on syntonic" ah, you fasten jest I, this also is academic to aerial practice to prove, with a ha breath out.
