I need to tune the antenna on my 27MHz CB. Is this the right meter, and does it read my handheld?

This meter is made for CB radio on the 27 to 30MHz band and handles up to 100W. It does not read VHF or UHF, so use the Surecom SW-102 or SW-33 Mark II for handheld radios on 125 to 525MHz.

What else do I need to start testing, and how do I take a reading?

You supply two 50 ohm coaxial jumper leads, which are not included. Connect the radio to TRANS and the antenna to ANT, set the mode to SWR and the range to 10W FWD, key a steady carrier, turn CAL to SET, then switch to REF.

My SWR reading looks high. Does that mean the meter is inaccurate?

A high reading points to the antenna system rather than the meter. Aim for 1:1 to 1.5:1 by adjusting antenna length and checking the coax and ground. Accuracy is around 5 percent on SWR and 10 percent on power.
