The tree has grown a foot since this was taken and these antennas are much less than obvious. The height is about 15m/50ft.
At the top is a Hentenna & reflector, you could call it a 2-element but it has more gain than a Yagi, and below a double 2-element Quad using a common reflector. I have no need for a rotator because in the missing direction is a 200ft cliff. The materials are 10mm/0.4inch copper which darkens with age, SRBP plates and terminations in a small ABS box with a lid.
Very well done Hugh! Magnificent actually! :shock:

I like the look so far but do you have bigger pics?

When the tree flowers with lots of pollen and sap, does it change your RF radiation?

Good question. Does it heat up enough to reodorize the area under such conditions?

Your holiday signal is 5x9 with a scent of PineSol! :rofl:

The tree smells good in warm weather, not like so-called "pine" scented disinfectant, and it exudes resin. I tried it as solder flux, it works well.
I'm not aware of any power loss, the Hentenna was good for an opening to the south of Portugal (5+9+), that's about 1100 miles using 30W, a few weeks ago, there's a bundle of coax down the tree and a switch for antenna selection in the shack. As far as heating goes I won't get much from 100W but I did take the precaution of moving the garden machinery fuel from the adjoining shed to a safer place.
Wouldn't it be a bit acrid as an electronic solder flux not to mention possibly dealing with stringy trails everywhere like a hot melt glue?
