Technical description

A monoband deltaloop is a wire loop with a full wavelength. The suspension determines the function of the antenna quite considerably, the easiest way is to mount it with the tip pointing upwards. The steel wire has a good tensile strength, so you only need one raised point and two more guy points near the ground.

The polarisation is determined by the position of the feed point. If the balun is down in the middle of the horizontal wire, the signal is predominantly horizontally polarised. If the balun is in one of the lower corners or slightly above in a slanted piece of wire, the antenna is predominantly vertically polarised. In all cases, the antenna in this design is a very good omnidirectional antenna. The gain is given in the literature as +3 dBD.

The balun supplied has a transmission ratio of 1:2, it is designed for a maximum power of 1000 W, connection PL socket. The Hari delta Loop is fully assembled. Only the three insulators supplied are not fixed to the antenna wire, as an individual fixing point must be found here for each installation. The required wire clamps for fixing the insulators are supplied.

Application description

The delta loop antenna is usually set up as a triangle, either with the tip pointing upwards (requires only one suspension point), or with the tip pointing downwards (requires two suspension points). The name comes from the similarity of the antenna to the Greek capital letter 'Delta' Δ.

The angle of radiation depends on the height above ground, even at a distance of only 2m from the ground a relatively flat angle of elevation of 20° is achieved for the maximum of the RIchtdiagram. This is very advantageous for long-distance connections (DX). Alternatively, you can set up a Delta Loop lying down, then you have a good steep radiator, good for local traffic.

The impedance at the feed point is also determined by the position of the balun. Depending on the height above ground, you will find a point with approximately 50 ohms on the sloping piece of wire near a corner. This gives a good match over a relatively wide frequency range.
