Note
The Palomar Engineers PT-340 Tuner-Tuner is a specialized device designed to allow the operator to tune their antenna systems without transmitting a signal over the air. It serves as a noise bridge that helps achieve a perfect 1:1 standing wave ratio silently.
The Tuner-Tuner is a compact unit that sits between your radio equipment and your antenna tuner. Its primary components and features include:
– Power Source: It operates on a single 9-volt transistor battery.
– A red panel lamp serves as a warning light to indicate when the device is turned on.
– Protection: It contains a 1/16 amp AGX fuse to protect its internal circuitry in case of accidental transmission while the unit is active.
Power Handling: When turned off, the device can handle RF power up to 1000 watts.
The device works by generating a loud broadband noise that your receiver detects. By adjusting your antenna tuner to minimize this noise, you are effectively matching the antenna's impedance to your transceiver.
Important Precaution
– No Transmitting While On: Never transmit when the Tuner-Tuner is in the "TUNE" position, as it may blow the internal fuse.
