- Page 3 Introduction Thank you for purchasing and using the Chameleon Antenna Universal Remote Tuner 1 (CHA URT1). 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.
- Page 4 Components The CHA URT1 consists of two units: a Tuner Unit and the Coupler Unit. The Coupler Unit is shown in figure (1). The Tuner Unit is shown in figure (2). The components of both units are described in the paragraphs below. Figure 1.
- Page 5 Figure 2. Tuner Unit. E. TUNER Indicator. The TUNER Indicator will be lit green when power has been applied to the Coupler Unit. F. TUNER Connector. The TUNER Connector is used to connect a coaxial cable from the Coupler Unit to the Tuner Unit. In addition to RF output, the Coupler Unit uses a bias-T circuit to send power and control signals to the remote Tuner Unit over the coaxial cable.
- Page 6 J. Ground Connector. The Ground Connector is used to connect a ground or counterpoise wire. K. ANTENNA Connector. The Antenna Connector is used to connect a coaxial cable fed antenna. The Antenna Connector and the Beehive Connector cannot be used at the same time.
- Page 7 Installation Options The CHA URT1 is designed to be used as a remote tuner. A remote tuner is where the Tuner Unit is installed outside near the antenna feedpoint, so loss due to high SWR on the feedline is avoided. Stainless steel brackets are included to facilitate installation of the remote Tuner Unit outside.
- Page 8 Antenna Configurations The CHA URT1 can tune almost any single wire or coaxial fed antenna. Three typical configurations are shown below. Random Wire Antenna The most popular antenna configuration used with remote tuners is a Random Wire Antenna, see figure (5). The key to installing a “random” length wire antenna is that it cannot be a half- wavelength on any band you want to operate.
- Page 9 Table 1. Minimum Counterpoise Wire Length. Vertical Antenna The CHA URT1 is ideal for an all-band ground-mounted Vertical Antenna, as shown in figure (6). For example, the classic 43 foot Vertical Antenna will have excellent performance on 160-6 meters, when used with the CHA URT1. Mount the Tuner Unit on a post near the base of the Vertical Antenna.
- Page 10 Figure 6. Vertical Antenna. Coaxial Fed Inverted “V” Antenna The CHA URT1 can also be used for tuning coaxial fed antenna, such as an Inverted “V” dipole antenna that has a BALUN in the center, like that shown in figure (7). The Tuner Unit should be located as close to the BALUN of the dipole as practicable, such as at the base of the mast.
- Page 11 Tuner Connections Connecting the CHA URT1 is easy since transceiver-specific control cables are not required. Simply connect the Transceiver to the Coupler Unit, the Coupler Unit to the Tuner Unit, the Tuner Unit to the Antenna, and apply 12V using the supplied power cable. Refer to figures (1) and (2) for connector details.
