Be prepared to experiment to learn how to operate
It arrived about 80% charged and included several coax adapters to convert from the SMA form to more common types. A nice added feature. The instructions are very poorly written and incomplete. A vitally important adjustment, the span of the scan, is not mentioned. From the scan screen, hold down the MODE key (F4) and turn the top knob to select the scan span range. Accuracy of the SWR measures seems accurate compared to my BIRD 43 meter. Screen visibility in bright sun is a problem. Bottom line, it works well once you flounder through the instructions and find the scan span adjustment.
