The Sigma Euro-Comm DELTA- 80 HP Multi Band Full Wave Loop Antenna Wire Antenna. The DELTA-80HP is a full wave loop designed to operate on 80m (3.5MHz), 40m (7MHz), 20m (14MHz) and 10m (28MHz) without an ATU and other bands with an ATU There is a 4:1 balun at the feedpoint enabling it to be fed directly with 50ohm coax – RG-213 or Mini 8 is probably the best but other variations of coax may be used so long as they are of a 50ohm impedance. The loop comes complete with six insulators to provide anchor points. It may be mounted flat (horizontal) or raised to a vertical or near vertical postion. It may be configured as either a square loop (Quad) or equilateral triangle (Delta). FULL WAVE DELTA LOOP. Configured as a delta loop or equilateral triangle, if laid flat will be good for near DX. If vertical, or near vertical will provide low angle radiation which is good for long range DX in the direction of the loop (looking straight on at the front) and near DX off the sides. Gain 3.2dBd. FULL WAVE QUAD LOOP If laid horizontally will be good for NVIS, if vertical 2.8dBd gain. Slopingat 45 degrees will provide low angle DX.
