My LoG is now under 3.5" of snow, and seems to be working fine.
I wasn't sure about the LoG at first, but I'm really happy with the performance of this antenna on the lower bands. This is a larger LoG, about 350 ft total perimeter. I am using it right now to listen to some of the pirate beacons on the 2 and 4 MHz bands, and it is working extremely well.
I also have a traditional 50 ft LoG which OTOH I am not very thrilled with so far. I need to spend some more time using it on the higher bands, when propagation permits. Which might be in a few years.
I'm now considering building a larger one, perhaps in the 800 to 1000 foot range. Time to check out eBay for some bulk wire deals.
