# Two different dipoles attached to three trees

I wish to erect two separate antennas, one 20 meter dipole and one 40 meter dipole. My property has 3 trees that are the correct distance apart from each other. They are oriented such that when the dipoles are in place, one end of each dipole will be connected to opposite sides the same tree (the middle tree) and the two antennas will be at a 90 degree right angle to each other. They could easily be at different heights above ground.

My question is, will having one end of each antenna being only about two feet apart and being at almost perfectly 90 degrees to each other cause any problems?

Thanks!

• My gut feeling is that they will be fine. You slso might consider a fan dipole, where both antennas are parallel to each other, spaced apart, and are fed with the same feedline. Commented Jun 16 at 13:01
• Why would you want to put up two antennas to double the cost and not buy yourself anything? You can put 20 and 40-meter elements on the same coax without issues. Commented Jun 16 at 16:00
• @Dereck That's why I suggested a fan dipole. However, it's possible that he's doing it to cover different directions (areas) on each band. Commented Jun 16 at 19:31
• If I had EZNEC working here, I would have modeled the two antennas. :-) Commented Jun 16 at 19:32
• Who said the two could not be in different directions? Think of an X orientation. The trick with fan dipoles is to separate the elements from each other. The two dipoles at right angles are as far apart as possible. Commented Jun 16 at 23:58
