📶 Accurate SWR/Power Meter for CB Radio Antenna: Mcbazel SURECOM SW-111 – 100 Watt Review

The meter could not detect RF on the 10W scale, therefore not suitable for CB (AM). Use a 30W dummy load and two different transceivers

Instructions don't stop until halfway through. What they don't mention is that the goal is that the SWR readings for channels 1 and 40 are ideally the same. Or be as close as possible. If the SWR on channel 1 is greater than on channel 40, the antenna is too short. extend it If the SWR on channel 40 is greater than on channel 1, the antenna is too long. make it short In theory, all channels in between are now within acceptable SWR limits. For me, almost all channels were well below 1:1.5…

The meter could not detect any HF on the 10W scale, therefore not suitable for CB (AM) use - otherwise compact device without characteristic intrameter chatter Reactive load 30 W and two different transceivers.

Meter failed to detect HF on 10w scale so not suitable for CB (AM) use - otherwise compact unit tested with no telltale internal rattling with dummy load of 30 W and two different transceivers

Meter failed to register HF on 10w scale so not suitable for CB (AM) use - otherwise compact unit with no telltale intrameter quatren included a 30W dummy load and tested two different transceivers

This instrument was anything but calibrated immediately upon installation. I tried recalculating using known standards and while the calibration went as expected, the results were inconsistent (i.e. the power readings were very different even at the same time/on the same sensor). I wanted a small SWR/power meter, but I can't rely on it even with poor accuracy and stable readings. Part of the SWR seemed to be working appropriately and correctly.
