Intellitron AA-3915 RF Isolator
The Intellitron AA-3915 RF Isolator is engineered to protect your radio setup from unwanted common-mode RF current on the coax shield. This essential accessory effectively prevents "RF-in-the-shack" issues, which can lead to equipment interference, data corruption, and uncomfortable RF burns during high-power transmissions. It also helps reduce local RFI that can degrade weak signal reception. Designed for high-power amateur radio operations, the AA-3915 acts as a barrier to common-mode energy while preserving your signal's integrity to the antenna. Its durable housing is built for reliable outdoor installation.
