Final Approach
The GNC420 I put in the 140 is wonderful, but in the installation process, we removed a NAV 121 that was NAV2. This left an open output on the antenna splitter. The NAV122 has always worked wonderfully, but is now weak. It won’t pickup the local VOR when at the test location on the airport. It picks it up once I’m a thousand feet or so up, but tests 6 degrees off. The audio from it is nothing but noise.
Could it be that disconnecting the VOR2 antenna from the splitter is causing an impedance mismatch?
