Trees with wet leafs on them tend to gobble up UHF uplinks. It’s not quite as bad on VHF but can have an affect.

Trees cause real attenuation on both 2M and 70cm. Near field effects are more pronounced that far field.
It's not a hobby killer but it will degrade your performance.
Trees are a hobby killer for EME on 2M and above.

Hi All- Just wondering-in the real world how much attenuation is there with trees? I am surrounded with fir trees, a huge maple tree and cedar tree, (I live in the north west). I run a IC-910, preamps at the cp yagis.
