about
OTA antennas:
...have this nice complex expensive hi-tech yagi antenna with lots of reflectors, directors, collectors, etc. - had her for many, many years and been doing fantastic job picking up those
REALLY weak local channels on my VIP211...
...recently though some of those channels have been 'coming and going' ~ actually seemed to do better when it rains (?!?) - I can actually hose it down and get great reception again (as an extra class amateur radio operator I just gotta figure this out!).
Turns out feakin' green algae was growing on the thing's metal parts - got up there and washed her clean and B A N G !!! just like a new antenna - pickin' up everything great now...
CONCLUSION: don't just look at grounding and cable connections!
