The new iP60z iPortable™ Antenna SWR Analyzer is designed for field use. This compact battery powered unit has an easy to read frequency display and measures SWR and impedance in the HF bands and VHF 6 Meter band. The SWR readings quickly show you the actual VSWR measurement and reads Magnitude of the impedance (Z). This is the easiest way to adjust your portable or base station antenna to be best matched for your radio. iP60z iPortable™ operates on HF bands and on VHF 6 Meter band!
