First foray into HF

After receiving my ticket last February, I'm finally making my first foray into HF.

I've decided upon a Yaesu FT-450D and will pair it with a W5GI "Mystery" antenna. I've got lots of tall Ponderosas and plan to string up this G5RV-similar antenna to them. I plan to affix the feed line (center) of the antenna to a branch about 35 feet up and create an inverted V with the legs at about 30 degrees.

Question- will the tree affect (one way or another) the radio waves (tx or rx) or will I be ok?

Thanks,

You should use insulators at the ends of the dipole and insure that tree branches aren't touching the antenna wires. Even if the wires are insulated you can have capacitive coupling to live tree branches that will affect your signal.

Hams routinely use trees as very cost effective antenna supports.
