Platt, NN4Y, takes a clear, practical approach to one of amateur radio's most widely used wire antennas. This is not a theoretical treatment-it is a real-world guide built on experience, careful observation, and proven results.\u003c\/p\u003e\u003cp\u003eStarting with the fundamentals, the book explains how and why the EFHW works, including voltage, current, impedance, and resonance. From there, it walks step-by-step through building a reliable transformer, selecting proper materials, and avoiding common construction mistakes.\u003c\/p\u003e\u003cp\u003eBut building the antenna is only part of the story.\u003c\/p\u003e\u003cp\u003eThis guide goes further, covering: \u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eWire lengths, harmonics, and multiband operation\u003c\/li\u003e\n\u003cli\u003ePortable setups, including Parks on the Air (POTA) field use\u003c\/li\u003e\n\u003cli\u003eHOA and stealth installations where antennas must remain unseen\u003c\/li\u003e\n\u003cli\u003ePermanent installations built for long-term reliability\u003c\/li\u003e\n\u003cli\u003eRF in the shack and how to eliminate it\u003c\/li\u003e\n\u003cli\u003eThe importance of common-mode chokes and proper current control\u003c\/li\u003e\n\u003cli\u003eNoise, grounding, and counterpoise considerations\u003c\/li\u003e\n\u003cli\u003ePower limits, heating, and safe operation\u003c\/li\u003e\n\u003cli\u003eLinked EFHW antennas, traps, and loading techniques\u003c\/li\u003e\n\u003cli\u003eTroubleshooting SWR problems with a practical, step-by-step approach\u003c\/li\u003e\n\u003cli\u003eHow the EFHW compares to other antennas-and when it should (and should not) be used\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThroughout the book, complex ideas are explained in plain language, with a focus on cause and effect rather than theory alone.\u003c\/p\u003e\u003cp\u003eWhether you are building your first HF antenna or refining an existing setup, this book provides the knowledge needed to make the EFHW work as it should-reliably, predictably, and effectively.\u003c\/p\u003e\u003cp\u003eThis is not a book about chasing perfect numbers.\u003c\/p\u003e\u003cp\u003eIt is about building an antenna that works-and understanding why it works.\u003c\/p\u003e","brand":"Independently Published","offers":[{"title":"Paperback","offer_id":47883697160343,"sku":"9798255872282","price":1044.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9798255872282.webp?v=1781103382","url":"https:\/\/atlanticbooks.com\/products\/end-fed-antennas-the-efhw-explained-properly-built-correctly-and-used-effectively-9798255872282","provider":"Atlantic Books","version":"1.0","type":"link"}
