What SWR meter should I buy?
Surecom Gam3Gear SW-102S SO239 Surecom is a relatively lesser known brand but this SWR meter from Surecom is the absolute best you can buy in its price range. There’s a reason it has managed to get almost universally positive reviews.
Are built in SWR meters Good?
A built in meter is a multi purpos meter. and often times they arent the most accurate thing in the world. An External SWR meter is built for one purpose and one purpose alone, and above and beyond that it is of higher quality than the internal.
Are all SWR meters the same?
You are correct – they are designed to cover specific frequency ranges. If you are (or know someone who is) handy with a soldering iron – you can modify a CB SWR meter to cover the range 1Mhz to well above 1Ghz at low power.
Is a SWR of 2 OK?
SWR 2.0 – 2.4: While not good, this likely won’t damage your radio with casual use. However, you should definitely try to improve it if you can. SWR in this range is usually caused by a poor antenna mounting location and/or a poor choice of equipment for your specific vehicle.
Can you use a CB SWR meter for ham radio?
4 Answers. Many hams have re-purposed CB SWR meters but there are so many variations that some caution and testing is warranted. Many CB meters were not designed to handle the higher power levels of amateur transceivers. A 100 watt transmitter could cause component failures within the meter.
What does SWR mean on a CB radio?
Standing Wave Ratio
(Standing Wave Ratio) All President antennas are delivered pre-adjusted. Nevertheless the environment and the location selected for the installation are as many factors liable to make vary the S.W.R. So it is important to check if your antenna is perfectly connected before using your CB radio.
How do you tune a CB radio with a built in SWR meter?
Turn the radio to channel 1. Key the microphone (depress the button and hold it). Turn the knob on the SWR meter labeled “SET” or “ADJUST” until the needle reaches the setting position at the end of its range. While still keying the microphone, flip the switch on the SWR meter to the “REF” or “SWR” position.
How is SWR calculated?
The VSWR definition states that the VSWR is equal to the maximum voltage on the line divided by the minimum voltage. The voltage fluctuations come about as a result of the voltage components from the forward power and the reflected power summing together.
What is a bad SWR reading?
It’s not nearly as noticeable as, say, going from 2.0 down to 1.5. SWR 1.5 – 1.9: There’s room for improvement, but SWR in this range should still provide adequate performance. SWR in this range is usually caused by a poor antenna mounting location and/or a poor choice of equipment for your specific vehicle.
