The Sigma Euro-Comm DELTA-15HP is a versatile full-wave loop antenna for multiple bands. It operates on 15m, 12m, and 6m without needing an ATU and works on 20m, 17m, and 10m with an ATU. The antenna features a 4:1 balun at the feed point, allowing direct connection with 50-ohm coaxial cables like RG-213 or Mini 8. It can be configured as a square loop or an equilateral triangle, offering installation flexibility.

With a maximum power handling capacity of 500W CW and 600W PEP, the DELTA-15HP provides a forward gain of up to 3.2 dBd. The overall loop dimensions are 13.60m, with three equal sides measuring 4.53m each for the delta loop configuration and four equal sides of 3.4m for the quad loop setup. The radiating wire is made of Poly flex weave non-kink material, ensuring durability and performance. The antenna's 4:1 HP feed point balun further enhances its efficiency and effectiveness in transmitting and receiving signals.

Whether mounted horizontally for near DX or vertically for long-range DX, the DELTA-15HP offers a gain of 3.2dBd in the delta loop configuration and 2.8dBd in the quad loop setup when positioned vertically. Additionally, sloping the antenna at a 45-degree angle provides low-angle DX capabilities, making it a versatile choice for various communication needs.
