I have 2 probably unconnected problems with my recently installed XM240 and
TH11. The XM240 is in-line 11 feet above the TH11. The TH11 is at 80ft. I
believe everything is assembled according to spec

1st the XM240: The front to back on the XM240 is almost non existent. Is
this the effect of the TH11 11ft below?

2nd the TH11: The resonant frequency really moves in the rain. 14/18/21
move down about 100K, 28M down 200K, and worst of all 24M down 250K. Yes
the trap holes are facing down. Plus there's no traps on 24MHz any way. Is
this typical?
