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. 73 Andrew Mid Wales. ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com ___ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
