Topband: Effect of trees- tree appreciation

[Greg Chartrand]

I expect the losses are related to current not voltage. The current of my antenna is in the vertical section for the most part and loss would would have to happen there as coupled to the nearest tree. The current would have to flow to ground so I seriously doubt if the resistance of the trunk is low enough to conduct any significant current to ground. Any loss in the top hat where the voltage is probably would amount to much power; the current has already flowed in the vertical section where I want it to. I had one of the top hat wires break once due to an apparent arc to a tree limb. My solution was wire with better insulation, so far so good.

 I couldn't care less about any speculated loss due to my trees. Without them I would not have an antenna on 160 so I figure I'm probably at least +50 db compared to my dummy load and many db better that a makeshift antenna away from the trees. 

I'd encourage anyone considering 160 to use trees to suspend an antenna if they are available. If I had a nice 100' tree in my backyard I guarantee you I'd use it. I also guarantee that I'd spend a hell of a lot of money putting up an equivalent tower in the open and the DB difference would not be worth the effort and cost  for me. 

Again, thank you trees.
