The low radiation angle for the Sirio Antenna Sirio GPE 27 5/8 is excellent for DX. The Sirio GPE 27 5/8 Antenna is designed for the 10m & 11m in frequency range. It’s omnidirectional and tunable by acting on the whip length, plus low radiation angle for excellent DX. The coil is protected by a transparent cover.

The whip is equipped with the waterproof jointing sleeve, also made of aluminum alloy 6063 T-832 offering protection from static discharges.

The ground plane frequency range: tunable from 26.4 to 29.0 MHz. Will do more with a tuner, because a video shows the operator transmitting on a 20m frequency.

Materials are aluminum, steel, copper, and nylon. Made of anti-corodal aluminum tubes and supplied with polythene jointing sleeves to be a perfect waterproofing. Strong and easy to install.

This looks like a solid antenna sold for a reasonable price.

Happy DXing.
