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.
