Page 7: Installation Options
Installation Options The CHA URT1500 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. - Page 8 Figure 2. Remote Tuner Block Diagram. If the CHA URT1500 is replacing an existing local tuner or is going to be used with already installed coaxial cabling, the CHA URT1500 can be used as a local tuner. A local tuner is where the Tuner Unit is installed inside, near the Coupler Unit, as shown in figure (3).

(4). For example, the classic 43 foot Vertical Antenna will have excellent performance on 160-6 meters, when used with the CHA URT1500. Mount the Tuner Unit on a pipe or post near the base of the Vertical Antenna. Connect a wire from the Beehive Connector on the bottom of the Tuner Unit to the base of the Vertical Antenna. -
Page 11: Coaxial Fed Inverted "V" Antenna
Coaxial Fed Inverted “V” Antenna The CHA URT1500 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 (5). 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 12: Tuner Connections
Connecting the CHA URT1500 is easy since transceiver-specific control cables are not required. The CHA URT1500 can be used to tune single wire fed or coaxial cable fed antennas.
