The side rt camera is 2.5 feet in front of the 5dBd gain to the right antenna array. The array has 10db front to back and passes in the oposite direction yields 10 dB less signal. The e73rd. segment shows the signal jump when the porch mounted antenna becomes unobstructed by the corner house . Also, the telephone pole and tree attenuate the direct path between the porch roof mounted Diamond antenna and the mobile RF array. All affected govt users have been notified.
My bet is: an 11 meter sweep tube amplifier, probably not push-pull on the Diamond 144/440 antenna on the porch roof. The amp is not type accepted, has no harmonic filter short of the output Pi network. The amp is not neutralized and with no drive, goes into oscillation which holds the rf input sense relay on.

Nice mobile setup BTW.
