Rohde \nRod antennas\, widely used in portable radio systems\, are crucial for r eliable communication in amateur and military contexts. These systems must perform well under varying environmental and ionospheric conditions\, whe re signal propagation is frequency-dependent. At any time of day\, an opti mal frequency or small band of frequencies between two points remains stab le for several hours. We can perform best by properly matching an antenna to this frequency. In this discussion\, we will introduce a combination of matching techniques that improve transmission and provide better coverage than previous methods.\nTalk 2: Some Further Thoughts and ideas concernin g the classical half-wave diploe antenna\, Invited Speaker: Prof. James Br eakall\nThe half-wave dipole is a popular antenna in amateur radio and com munications\, often the first studied in college courses. Professor R.W.P. King dedicated over 100 years to dipole research\, and his accurate measu rements support antenna modeling software. Professor John Kraus’s 1950 b ook\, *Antennas*\, has also inspired many in the field. This presentation will cover key topics related to the half-wave dipole. We will evaluate th e accuracy of various antenna modeling codes\, using a FEKO surface model as a reference and comparing it to wire Method of Moments (MoM) methods. A dditionally\, we will review the formula 468/f for calculating the length of a half-wave dipole in feet and discuss its limitations regarding differ ent wire or tubing diameters. Finally\, we will introduce a new design met hod for constructing a half-wave dipole antenna that works regardless of t he conductor's diameter.\nTalk 3:The State-of-the-Art in Antenna-based Tec hniques for Mitigating Threats to the Global Positioning System (GPS)\, In vited Speaker: Jack L. Burbank\nNearly every aspect of society relies on p ositioning\, navigation\, and timing (PNT) services from Global Navigation Satellite Systems (GNSS)\, like GPS. However\, GPS signals are vulnerable to spoofing and jamming due to their unauthenticated nature and weak sign al strength. These attacks can be easily executed using low-cost hardware and open-source software\, putting many regions at risk. Research over the past few decades has aimed to improve PNT performance against these threa ts\, focusing on five main approaches: 1) signal processing methods\, 2) a ntenna-based techniques\, 3) artificial intelligence (AI)\, 4) non-GNSS se nsors\, and 5) hybrid methods. This presentation will provide an overview of GPS and GNSS technologies\, common attack strategies\, and mitigation m ethods\, emphasizing antenna-based techniques. It will introduce a classif ication of these methods\, aiming to enhance authentic signal reception wh ile reducing interference from attackers. Key techniques\, ongoing researc h\, and future directions will also be discussed.\n\nTalk 4:The High Frequ ency Active Auroral Research Program\, “HAARP”\, A Brief History and E ngineering Review. Invited Speaker: Steve Floyd\nThe HAARP Research Facili ty is a state-of-the-art ionospheric research project in Alaska\, funded b y the U.S. Air Force\, U.S. Navy\, and DARPA. Constructed by APTI/BAE Syst ems\, it analyzes the Earth's ionosphere to enhance radio communications a nd surveillance. Construction began in 1993\, research operations started in 1996\, and the facility was completed in 2007. In 2015\, control was tr ansferred to the University of Alaska Fairbanks (UAF). The main instrument \, the Ionospheric Research Instrument (IRI)\, consists of a 180-antenna p hased array operating at 5 gigawatts\, making it one of the most powerful high-frequency transmitting systems globally. It temporarily excites areas of the ionosphere for scientific research and is also equipped with VHF a nd UHF radars\, magnetometers\, and low-light CCD cameras. HAARP is noted for addressing unique challenges in radio engineering. This presentation w ill summarize the facility's design and operation\, along with examples of the scientific research conducted there.\nTalk 5: RCA – Where History M eets Innovation\, Invited Speaker: David Bart\nThe Radio Club of America w as founded in 1909 by enthusiastic young experimenters in wireless telegra phy. It quickly became a magnet for innovators\, entrepreneurs\, inventors \, industry leaders\, and historians interested in all aspects of communic ation without wires. Our pantheon of legendary members continues to hold s ignificant roles in developing radio\, television\, mobile communication\, satellite\, space research\, mmWave\, and digital technologies. We are a forum\, a gathering place for professional\, scientific\, and amateur prac titioners of these arts. Join us for a collegial discussion about how hist ory meets innovation.\n\nCo-sponsored by: IEEE North Jersey Section AP/MTT 17\, ED/CAS\, PHOTONICS Chapter and Radio Club of America (RCA)\n\nSpeaker (s): Prof. James K.
