The CHA URT1 is a remote outdoor tuner for almost any type of antenna and any brand  or model transceiver. The CHA URT1 is unique in that it can be used for coaxial cable or wire fed  antennas. This wide-range tuner will match wire antennas, such as a vertical, random wire  antenna, or a long wire antenna. It can also be used with coaxial-fed antennas, like an Inverted  “V” or dipole. Also, the CHA URT1 does not need a transceiver-specific control cable, so it works  with any brand or model of transceiver. The rugged Tuner Unit is weatherproof and designed to  be permanently installed outdoors at or near the antenna feed point, so loss due to high SWR on  the feedline is avoided.
The CHA URT1 covers 1.8 – 54.0 MHz and has 16,000 memories for quick recall and tuning with  previously used settings. It can match any antenna with an impedance of 5 to 1,500 Ohms within  seconds and can handle up to 125W SSB Phone & CW, 100W SSB Phone & CW on 50 MHz, 60W all other modes (see specifications tab).  The CHA URT1 consists of two units: a Coupler Unit and the Tuner Unit. The  Tuner Unit is in a rugged weatherproof housing and contains the antenna matching  network and controller. It is normally installed outside at or near the antenna feed point.  The Coupler Unit contains the operator controls and status indicators. It uses a bias-T circuit  to send power and control signals to the remote Tuner Unit over the connecting coaxial cable,  so there is no need to order or install a separate transceiver-specific control cable. The Coupler Unit is not weatherproof and must be installed inside near the operator and  transceiver.
These tuners use latching relays. Once the tuner is tuned the relay’s latch and power is turned off. It saves on battery drain. The tuned frequency will be stored in memory. When you change frequency or bands you need to apply power and energize the tuning process again. If the frequency is in memory the tuning process will be quick !
