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

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. Channels 12-25 were 1:1.
