If, due to space limitations, the antenna can not be installed in a horizontal manner, the inverted-V mounting is a good alternative. The radiation angle is lowered and more suitable for DX, and only one center pole is required for installation. The angle between the two dipol side should be between 90 and 130 degrees, and it should not be less than 75 degrees. The ends of the wire should not touch the ground but end some meters above ground, perhaps they require extensions with insulating rope.
