water from entering the coax. (Note: this connection when made properly is sufficient to support the heavy coax feedline.)

Halyards can be fastened at the feed point and ends to raise the dipole and provide a means of adjustment of feed point impedance by adjusting the height of the antenna while observing the SWR at the design frequency. Since coax is heavy, end insulators with sufficient strength should be used to support the antenna, it is desirable to support the center of the antenna as high as possible and adjust the ends for lowest SWR at the design frequency, The reason for this is because most of the radiation takes place from the center part of the antenna, The antenna lends itseli to be used as an inverted very nicely with an increase in bandwidth over the usual wire inverted "V" which generally has a narrow bandwidth due to a sharp apex angle.

Two of the described antennas have been constructed at this QTH with results as presented, see Fig, 5. No gain or fantastic increase in signal strength is claimed with this antenna as it is still onl\ a dipole but the improvement in operation at frequencies far from design resonance is advantageous and noticeable* This improvement could be considered as a gain. Many hams throughout Michigan, Indiana and Ohio are using this antenna on 75 meters with variations in construction as shown with similar results as presented.
