What does an SWR reading of 4 1 indicate?
What does an SWR reading of 4:1 indicate.
Loss of -4 dB.
Good impedance match.
Gain of +4 dB.
Why does my SWR go up when I talk?
One of the most common causes of high SWR readings is incorrectly connecting your SWR meter to your radio and antenna. When attached incorrectly, readings will be reported as being extremely high even if everything is installed perfectly.
Does antenna gain affect reception?
Higher gain antennas can increase your reception (it will be directional and match the transmission pattern of that specific antenna.). 2. You are still at the mercy of the weakest transmitting power (distance).
Does coax length affect SWR?
“the length of the feedline will not change the swr it will change the apparent reading depending on what wave length you read the swr at. . just as adding a signifigant length of coax, the resultant loss will look like a lower swr.”
Does SWR increase with power?
SWR really doesn’t increase with power. It’s always the same.
How do I increase the range on my CB radio?
There are several procedures for ensuring maximum output.TUNE THE RADIO. A CB radio is only as good as the coax and antenna connected to it. … USE CB-SPECIFIC ANTENNAS. … ESTABLISH A GROUND PLANE. … CHECK THE VSWR. … ELIMINATE RESISTANCE.
Is higher or lower antenna gain better?
The higher the dBi number of the antenna, the higher the gain, but less of a broad field pattern, meaning that the signal strength will go further but in a narrower direction, as illustrated in the diagram below.
What is an acceptable SWR?
What is a good SWR reading ? The best reading possible is 1.01:1 (46dB return loss), but usually a reading below 1.5:1 is acceptable. Outside the perfect world a 1.2:1 (20.8dB return loss) is spot on in most cases. To ensure an accurate reading, it is best to connect the meter at the base of the antenna.
What does an SWR reading of 1 1 mean?
What does an SWR reading of 1:1 mean? The best impedance match has been attained. An antenna for another frequency band is probably connected. No power is going to the antenna.
Can SWR be too low?
An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. … If you have an antenna that’s say, three feet or less, and the SWR tunes great (less than 1.5) across all the channels than maybe your antennas feedline coax or the antenna coil is “lossy”.
Does SWR affect reception?
Simplified answer: There is no relationship between SWR and receive performance. … SWR is a measure of the impedance mismatch between your antenna and transceiver. Whether transmitting or receiving, a higher SWR correlates with a less efficient coupling of energy between the transceiver and antenna.
