Hi Dale,
You are right...
1 - AC powered Kidde alarm Model# 900-0121.
2 - Antenna is about 100 feet from Alarm. Alarm is
on a wall about in the middle of my QTH.
3 - 4 element 20 at 60 feet and 2 element 40 at 70 feet on the
same tower. Only happens when antennas are aimed at house.
4 - Running Acom 2000A amp at 1000 Watts output...
73,
Ted K2QMF
