Inverted Vee Antenna Radiation Pattern - Mounting the antenna to the mast: Web captive washers to secure the boom to the antenna. Web the horizontal axis is distance in km. The two antennas can share the same support, but i would orient them at a 90 degree angle to reduce interaction. Each center was 50 feet high. The dipole was uniformly 50 feet high, but the inverted vee sides slope down at 45 degrees, It can be clearly understood by the radiation pattern shown below. This halfwave elevation provides the maximum signal to the sides with minimum signal skyward. Their rugged, yet simple design allows quick installation into. I modeled both a dipole and inverted vee at 3.8 mhz using eznec.
