McbazelSURECOM SW-111 100 Watt SWR/Power Meter for CB Radio Antenna

For the low price I wondered if it would work at all, but it worked quite well. It's easy to use and gives what I believe to be accurate readings. There's a lack of instructions so if you've never worked with one of these devices before, then I would advise you to do a YouTube search and learn a bit before using. It's not hard at all, but if you don't set it up right then you might accidentally damage your CB. You'll have to buy a short cable separately because it's not included, but those are available for cheap right here on Amazon. I recommend getting a 2 ft length, but that's just my preference.

Seems to work as it should. Seems fairly accurate. For the price it's a good deal. I bought the "used like new" thinking as long as it works it's a good deal. Power meter Seems accurate too, at least close enough for what it's worth. It's not an expensive unit so my expectations were high and we're met or exceeded.

The meter was a bit smaller than I expected. It also did not have rubber "feet"--easily remedied with some stick-ons from the hardware store.The SWR function worked as expected at power levels above 10 Watts. At lower levels, it underestimated the actual SWR.The power meter function is highly frequency dependent. It appears to have been factory calibrated for 27 or 28 mHz. The power calibration is adjustable with the two "mini-pots" as seen in the picture. The left-hand pot adjusts the low (10W) range, and the right hand pot adjusts the high (100W) range. At lower frequencies, the meter is much less sensitive so the calibration is way off. However, the readings are consistent, so I constructed the following table. To get the (approximate) actual power, simply multiply the meter reading by the appropriate "multiplier" in the table, which were determined using an FTDX101 into a 50-ohm dummy load.BAND MULTIPLIER80M.........10040M...........2530M...........1020M.............517M.............2.515M.............212M............1.610M............1.06M...............0.5

Muy bueno

Seem to work great out of the box

Love this meter’s compact size and also that the coax connects in the back instead of on the sides. The watt meter is probably accurate since I compared this SW-111 to another SW-114 and the power readings were the same. But the most important part, the SWR readings, did not agree between the meters. I tuned my antenna using the SW-114 and had the SWR equal on channels 1 and 40, then checked it with the SW-111 meter and it showed I was way off and needed to raise the antenna. Not sure which was right, I asked online and was advised to steer clear of these cheaper meters so I found an old Radio Shack Micronta on ebay, still new in the box, and got it. It also showed my SWR was way off, but in the opposite direction of what the SW-111 had shown. So instead of raising, I shortened the antenna until the readings were equaled out on the Micronta meter, and I am getting great reception and also seem to transmit pretty good as well. So I concluded that both Surecom meters were inaccurate and returned them both. If I had just stopped with the first meter, and believed the SWR was good, I might have damaged my radio.

I think the first one I got was messed up but they sent me another one and it works great and it's small so it's easy to carry on the go looks well made easy to use

Very sturdy and small. Used it set up (and occasionally verify) the SWR on my CB antenna. Note that I think they use the same meter display on other products and this one is the budget model which doesn't have the field strength feature so ignore that portion of the meter. Works great for SWR which is all most people need.
