From tonight (just after midnight) at the new 1,500 ft WVAH-TV tower in Putnam County, WV:

Set up a few hundred yards from the tower base and aimed the camera nearly straight up. Zoomed in all the way on the antenna tip. Rain on the lens was a problem but still got it. There were more strikes to the tower after this but everything was getting soaked and I had to bail. Been trying this shot now for 2 years, it is harder than it seems.

The lightning channel is looping so much because the camera is directly under it, looking almost straight up at the lightning coming down (you usually are looking at it from the side). The beading-out channel moves sideways with the strong winds, along with a shower of glowing sparks from the antenna tip. The lightning channel also splits into two branches about 20-30 feet or so above the antenna.

If you are in to lightning, the television tower is your friend.
