Antenna analyzers

Currently, a large group of instruments is being produced, usually in a portable version, for measuring the key parameters of antenna-feeder devices (AFDs): standing wave ratio (SWR, also VSWR), return loss, cable loss, distance to fault in the cable (DTF), etc.

All these devices are united by a single name – AFU analyzers, but there are also names: SWR meter, VSWR meter, AFU meter, antenna meter, SWR analyzer, antenna analyzer, reflectometer and Sitemaster. The last term come from the Anritsu device of the same name, which currently holds more than 40% of the world market: Anritsu S331E, S332E, S361E, S362E.

Tehencom company supplies a large number of AFU analyzers and SWR meters.

Below are the most popular AFU, cable and antenna analyzers. Regarding prices and delivery times for the entire range of instrumentation, simply call us or write to us at E-mail and we will be happy to answer your questions.
