On 1750m and 2200m, the vertical's signal will get eaten up by those trees. I am using a 70' inverted L vertical on 600m that is hanging in tall oak trees. The vertical portion is within 5' of one tree. There are about 27 trees in my quarter acre lot so you get an idea of what I am working with. I don't have an issue radiating a decent signal on 600m with this antenna with anywhere from 3w QRP to 100w. My CW by the ear at 3w is a bit over 100 miles and at 100w it has been heard at 274 miles. All at high noon daylight. At night that 3w goes out around 800 miles and 100w goes 1000+ miles by the ear copy on a good winter night. So, use a vertical wire in the trees on 600m, it'll be fine. If you want a TX loop, then a TX loop built as an Ashlock Loop, will work on any band, in the woods with heavy trees or out in a bare field with a couple towers to hang it on.
