Start with the decision: Protect CHA RXL from transmitted RF, lightning, weather, cable strain, and rotator load; a receive-only amplifier can be damaged even when the receiver itself appears protected.
What changes the result
The direct loop-amplifier-coax-bias-T chain, rotator, receiver protection, transmitter separation, weather exposure, and station switching determine whether the discontinued RXL remains safe and useful.
The mistake to avoid
Never transmit into the RXL or insert an unverified device into its powered signal path. Broad receive coverage does not establish transmit capability or overload immunity.
Use this practical sequence
Remove DC and RF, verify station interlocks and separation, inspect loop/amplifier/coax/bias-T/support, then test receive signal-to-noise while rotating—not transmitter SWR.
