"Hello IRCA'ers
I have a 12' x 33' Flag antenna. We have had recent snow here in the UK. The 
bottom wire of my Flag is under some 2 foot of snow. I feel I have lost some 
directivity with the antenna. Can the snow affect the directivity of a Flag 
antenna? If so, I'll dig it out of the white stuff despite the sub zero 
temperatures outside hi! Any help appreciated and my best wishes for 
Christmas to one and all from a very Christmas looking "ye Merrie oldie 
England."


Barry,  I had a similar issue with a K9AY antenna about 10 years ago. The 
base wires dipping in the snow screws up the directivity. My current K9AY 
phased array has both antenna base wires elevated 1.5m off the ground. I 
have snow here too and there is no degradation in the array directivity.

I would recemmend that you raise the bottem wire of your Flag to at least 
4ft above the ground, but you may need to raise the Flag height too, to 
retain the antenna gain.
