Refining an End Fed Antenna I could, of course, simply use a portable antenna tuner. 1. The measurements below are for building a simple Dipole Antenna. Although this design has been around for a long time, it is only gaining popularity now due to the recent improvement in high power antenna tuners. , a 40m dipole may also be used on 15m), but if it is fed with coax, it should not be used on its even harmonic frequencies. Full wavelength triangular loop sloper antenna (overhead view). The pattern from the antenna would suggest that it is a good DX antenna and my experience would confirm that it does well if you can find A delta loop fed from the bottom or top is horizontally polarized and can be vertically polarized by feeding it from a corner at the base.
