SUMMARY:OARC Monthly Meeting - May 2026
DESCRIPTION:The OARC Monthly Meeting will be on May 13\, 2026 at 6:45pm. All Amateur Radio enthusiasts are welcome: OARC members and non-members\, experience Amateur Radio operators\, new hams\, those who have yet to pass the exam\, friends and family. \nMost monthly meetings will be hybrid. Attendance options: \n(1)    Attend in person at Scouts Headquarters\, 1345 Baseline Road. Parking is free.\n  CLICK HERE TO GET A FREE TICKET.\nThis link takes you to Eventbrite\, a free online ticketing system. \nPlease register in advance for the meeting so that we can be sure to: \n\n\n\n\n\nHave enough chairs and refreshments for everyone\, and\nSend you a reminder closer to meeting.\n\n\n\n\n\n(2)   Attend online: Microsoft Teams Need help?\nClick here to Join the meeting now [expired] \nMeeting ID: [expired]\nPasscode: [expired] \nPhotos may be taken. Portions of the meeting may be recorded. \nAGENDA\n\nWelcome  (Roger\, VA3EGY)\nClub business updates (Roger\, VA3EGY)\nFeatured presentation: The Amazing Hex Beam (Craig VE3OP)\nThe hex beam has earned a reputation as one of the most efficient\, lightweight\, and cost-effective directional antennas. In his presentation\, Craig Delmage (VE3OP) will explore the design principles behind the modern hex beam; explains how its unique geometry delivers strong gain and front-to-back performance; and compares it with more traditional antennas such as Yagis\, dipoles\, and verticals. He will cover its discovery\, origins and evolution; specifications\, design and construction; performance data; primary manufacturers and pricing; mounting and rotor options; installation tips; and the pros and cons of commercial versus homebrew versions. Craig will also showcase his own hex beam and installation process through photographs.\nWhether you’re considering your first directional antenna or considering a change to your station\, this session will help you understand the amazing hex beam—and whether it is right for you. \n\nUpdate on Club Strategic Goals\n\nEducation update (Bert\, VA3PXE)\nEquipment update: Repeater project (Barry\, VA3FCQ\, Project Manager)\nActivities update: Field Day Plans (Mike Kelly\, VE3FFK)\, and other upcoming activities\n\n\n\n\nMonthly Meeting improvements\n\nNew! Surprise segment with prizes\nNew! Show and Tell segment\nNew! Meeting participation prizes

SUMMARY:End-Fed Half Wave Antenna Build Workshop
DESCRIPTION:*** REGISTRATION IS NOW CLOSED *** \nThe End-Fed Half Wave (EFHW) Antenna Build Workshop will be of interest to anyone who has a multi-band HF amateur radio with up to 100 Watts of transmitting power.  Assemble a 49:1 Un-Un transformer in mounting hardware with a SO-239 feedline connector\, and optionally connect an antenna wire suitable for 80/40/30/20/17/15/12/10m or 20/17/15/12/10m bands.   \nDate: 31 May 2026\nTime: 13:00-17:00\nCost:  Non-members pay $10 more  *** REGISTRATION IS NOW CLOSED ***\n[] $75 – EFHW Antenna workshop with Un-Un transformer only\, no antenna wire\n[] $85 – EFHW Antenna workshop with Un-Un transformer AND 34’ antenna wire (20/17/15/12/10m bands\, suitable for portable use)\n[] $120 – EFHW Antenna workshop with Un-Un transformer AND 132’ antenna wire (80m band\, also resonant on 40/30/20/17/15/12/10m\, suitable for permanent installation)   \nLocation: Scouts HQ (1345 Baseline Rd Ottawa\, ON K2C 0A7\, Canada)  \n  \nWORKSHOP OUTLINE \n1. Introduction\nDefinition and Purpose: An End-Fed Half-Wave (EFHW) antenna is a popular resonant wire antenna designed to be one half-wavelength long at its lowest operating frequency. Unlike a center-fed dipole\, it is fed at the end\, providing high installation convenience\, and it naturally resonates on both odd and even harmonics of that base frequency.\nBasic Components: 49:1 Un-Un transformer\, feedlineconnector\, mounting hardware\, antenna wire   \n2. Design and Construction (overview of tools\, materials and techniques)\nMaterials Supplied: 2 x 240-43 torroids; 100 pF capacitor; 14-gauge enameled wire; PVC junction box; cable ties; SO-239 and misc. hardware.\nConstruction Techniques: PVC junction box will be pre-drilled  \n3. Hands-On Building Session (assembly and troubleshooting)\nPractical Assembly: Participants build their own 49:1 Un-Un transformer in PVC junction box under supervision\, applying the techniques learned.\nTroubleshooting: Guidance on common issues that may arise during construction and how to resolve them.   \n4. Testing and Tuning (performance testing\, tuning techniques)\nPerformance Testing: Instructions on how to test the Un-Un and antenna’s performance using SWR meters and other tools.\nTuning Techniques: Methods for adjusting the antenna for optimal performance\, including compensation coil\, coax counterpoise\, middle-of-wire capacitor   \n5. Conclusion and Q&A (wrap up and open discussion)\nWrap-Up: Summary of key points covered in the workshop.\nOpen Forum: Opportunity for participants to ask questions and share experiences related to EFHW antennas.
