This tuner is designed to match remotely , balanced HF antennas. This unit features automatic selection of tuner settings based upon transmitted frequency. Unique to this tuner, no special cabling or adapt ers are required. The operator simply transmits into the antenna and the tuner detects the transmitted frequency and selects the correct settings from memory. The Ham bands are divided into 85 operator programmable memory locations. It will handle 1500 watts of SSB or CW power, and it can be used in either automatic or manual mode. The matching circuit consists of a remotely tuned balanced π circuit. The balun is placed at the input of the tuner. The Output capacitor is a stepper motor controlled High Voltage variable capacitor. The Control Cabinet contains the tuning controls, memory location selection, Automatic or Manual switching and a display that indicates the memory location in use, the frequency range as well as the span, and the tuner settings.
Matches balanced Antennas (Dipoles, Loops, Inv. Vees, etc.) for Frequencies from 1.8 MHz to 30 MHz.
Optimum Usage of available Space for the Antenna
Antenna without Traps!
No RF Ground (Counterpoise, Radials, etc.)
Low Impedance Coax Cable from Shack to Tuner (Remember Computer, DX-Cluster, RF in the Shack etc.!!)
600 Watts Continuous Power, 1500 Watts SSB/CW when tuned
85 Memories to Store and Frequency dependent Automatic Recall matched Values
Consequent balanced Ciquit Design to match complex Antenna Impedance. Balancing
is done at the Input Terminals where the Impedance is purely resistive when the Antenna
