Is 1.5 SWR good?
SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. Occasionally, due to installations or vehicle variables, it’s impossible to get SWR lower than than this. You should try to get it lower, but performance should still be acceptable in this range.Click to see full answer. In this regard, what…

You should try to get it lower, but performance should still be acceptable in this range.Click to see full answer. In this regard, what is an acceptable SWR?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.Additionally, can high SWR damage a radio? Sure, it’s possible. High SWR can reflect enough power back into the radio to create enough heat to cook the final RF transistor. It isn’t usually an immediate failure, it takes some time for that heat to build up and do damage. Also know, 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. Safe operation of your CB should be with an SWR of 2:1 or less. Most people would prefer to be 1.5:1 or less. We EXPECT a high quality “short” antenna to be narrow banded.Why is my SWR reading so high?The most common cause of a high SWR is an antenna shorted to ground. There are two places a short can occur in a CB antenna system, in the coax and in the antenna stud.
