ANTENNA_TUNING_INDICATOR

The stealth antenna tuning indicator consists of a sensitive reflected-power bridge and indicator (R2 to R6 and associated components) and a switch (S1) that lets you route your transceiver's power into a dummy antenna (TUNE) or your antenna system (OPERATE). One more component, R1 (a resistance cortsisting of two separate 3-W resistors, R1A and R1B), leaks just enough of your transmitter's power to the bridge and your antenna system to allow low-interference tune-up when S1 is set to TUNE.
