Demonstrates the design principles and performance characteristics of **corner reflector antennas**, emphasizing their high gain and directional properties. It covers critical design factors such as the corner angle and the spacing between the radiating dipole and the reflector vertex. The resource explains how reducing the corner angle increases gain but lowers feed impedance, making matching more challenging. Practical angles of 90 degrees or 60 degrees are discussed, with 90 degrees offering easier impedance matching despite slightly lower gain. Details key design considerations, including reflector side length exceeding two wavelengths and reflector width greater than one wavelength for a half-wave radiator. It specifies reflector construction using wire netting, sheet metal, or parallel metal spines spaced less than 0.1 wavelength. The article provides a table with general dimensions for UHF and VHF bands, noting typical impedance values of 50 to 75 ohms and expected SWR of 1.7:1 on the lower band edge. Adjustable radiator-to-vertex spacing is highlighted as crucial for final tuning.

The **Luis Trenker Award** is an amateur radio operating award established by the Amateur Radio Club Ladinia to honor the director and author Luis Trenker from Val Gardena, South Tyrol, Italy. To qualify for the award, HF stations must achieve five confirmed QSOs with each of five specific Alpine countries: Italy (with specific prefixes like I1, IK1, I2, I3, IN3, IW3, IV3), France, Germany (with DOKs A, C, T, U), Switzerland or Liechtenstein, and Austria (with prefixes OE2, OE3, OE6, OE7, OE8, OE9). A single QSO with a member of the Amateur Radio Club Ladinia can substitute for the five required Italian QSOs, with members' QSL cards bearing a special rubber stamp. VHF/UHF stations have a simpler requirement, needing only one confirmed QSO with each of the five Alpine countries. SWL stations are eligible under the same conditions as transmitting stations. All contacts must be valid after April 12, 1990. Applicants must submit a list of contacts, certified by two OMs or a club, to the Amateur Radio Club Ladinia in Ortisei, South Tyrol, Italy. The award manager is IN3PGS Karlheinz, and the club official is IW3AQL Luca.

The author explores enhancing the performance of a 7-meter fiberglass squid pole wire antenna for amateur radio. The wire, resonant at 10MHz, poses impedance challenges on various bands. Experimenting with direct coax feed and UN-UN transformers, the LDG Z11-Pro2 auto-tuner is found effective but may show deceptive SWR readings. The author employs adjustable UN-UN ratios and introduces a custom "porcupine" coil to optimize the antenna's efficiency.
