How does the HF360 XP work?
The Sigma Euro-Comm HF360 XP is powered via 50 Ohm coax with a SO-239 connection at the base. A 4:1 UNUN transformer is located at the base of the antenna, housed in an IP65 sealed enclosure. This provides for more efficient impedance matching and improved tuning via an external ATU or the automatic tuner of modern transceivers.
The antenna consists of four sections: three fiberglass elements and a stainless steel tapered boom. If necessary, the antenna can be grounded to reduce static interference, without affecting the tuning thanks to the DC-grounded UNUN.
