What is the difference between an SWR meter and an antenna analyzer?
An antenna analyzer has a low-power signal generator built in. If you use a SWR meter, you have to use a separate one; if you use your regular transceiver for the purpose, you’re limited to its lowest power setting, which might be a few watts!
What SWR is too high?
For instance a SWR too high (over 3:1) all over the band can be an indication of a bad part or junction, poor ground or poor location. An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. Safe operation of your CB should be with an SWR of 2:1 or less.
Is 1.7 SWR good?
SWR Range Explanations. SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. If you’re at 1.5 and really, really want to drop down to closer to 1 it’s likely possible to do with addition tuning, different equipment or a different mounting location.
How do I test my antenna performance?
The general approach to antenna tests is to position a known transmitter and antenna at a known distance away from the tested antenna. The tested antenna is connected to a known receiver. The magnitude of the transmitter output is known, as is the loss of any cabling.
How do you measure dB loss in coaxial cable?
Cable Loss can be measured using the Return Loss measurement available in the cable and antenna analyzer. By placing a short at the end of the cable, the signal is reflected back and the energy lost in the cable can be computed.
Do you need an SWR meter?
To tune your antenna, you will need to use a SWR meter. This device is attached between your antenna and radio. This device measures the amount of signal being reflected into your transmitter to help you measure the quality of your outgoing broad cast as well as any potential threat to your radio.
What causes high SWR reading?
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. Please see this article on ensuring your SWR meter is properly installed.
