Why is SWR important?

Why is SWR important?

Why is SWR Important? SWR is very important because if you have a high SWR reading then your antenna will not be performing as well as it was designed to, and will not be transmitting all the power you have put into it, therefore you will not achieve the best transmit range.

Is 1.9 SWR good?

SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. SWR 1.5 – 1.9: There’s room for improvement, but SWR in this range should still provide adequate performance. Occasionally, due to installations or vehicle variables, it’s impossible to get SWR lower than than this.

Will a CB SWR meter work 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 kind of SWR meter do I Need?

I have found that the old Micronta CB 3 range power/modulation/SWR meters work quited well on 2 meters (probably better than they did on 11 meters). These are the 3 dial meters left to right power 5/50/500 watt range, modulation and SWR.

How is the SWR measured on a ham radio?

Basically, to measure the SWR, you adjust the pot so that the power meter reads full scale. Then, you can read the SWR directly from the SWR meter. To measure the power, you have to set the pot to a pre-set position. This is different for each band. Needless to say, this measurement is not very accurate.

What should my SWR be at 146.00 MHz?

For example, I may have an SWR measurement of 1.5:1 at 146.00 MHz, but if I were to tune my radio to 147.00 MHz, the SWR would be slightly different, perhaps 1.6:1 When tuning your antenna, it is important to choose a low SWR across the band you wish to operate on.

Which is more accurate a SWR meter or CB meter?

The reading you see on the meter will be very close to your real SWR. The closer to 1:1 your SWR is, the more accurate it will be. It would be more convenient to have a real SWR meter or antenna analyzer if you do a lot of testing, but for a quick antenna check after a mobile install or whatever, the $5 CB meters work OK.
