• AT-502 - Automatic Remote Controlled RF Antenna Tuner 200 Watts for Random Length Dipoles or Loops  1.8 to 30 MHz


Antenna Tuner System AT-502 Description
 
This tuner is designed to remotely match balanced HF antennas. 

This unit features automatic selection of tuner settings based upon transmitted frequency. Unique to this tuner, no special cabling or adapters are required. The operator simply transmits into the antenna and the tuner detects the transmitted frequency and selects the correct settings from memory.

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 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.


 


Manually tune band segments and memorize settings. In operation the tuner will recall the settings for a given band segment when it detects the RF.

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.
