LRT (Loop Remote Tuner) · Tuners & Matching
A tuning, matching, analysis, or remote-control device for a documented RF system.
Why operators make room for it
Know the match before the operating conditions make the decision for you
A promising antenna setup is still an unknown until the operator can measure it and bring the system within a safe operating range.
That is where CHA LRT (Loop Remote Tuner) enters the kit. The Loop Remote Tuner allows for remote tuning of the F-LOOP 2.0 and 3.0 magnetic loop antennas. This permits the antenna to be mounted away from the operating position, such as on a balcony or deck, and enables precise tuning of the loop. The LRT replaces the manual tuning knob with a motor housing and is controlled by a wired battery powered control box featuring fast and slow tuning buttons.
For the operator, the value is confidence: a measurable, repeatable path from antenna assembly to a verified match within the device and system limits.
