  1. very ham needs at least one antenna, and most hams have built one. This chapter, by Chuck Hutchinson, K8CH, covers theory and construction of antennas for most radio amateurs.

  3. Build a Classic Multiband Dipole Antenna. We. e amateurs have been using it for more than 100 years. This antenna will allow you to operate on several HF frequency bands, and it radiates signals eficiently, sending much of the RF en. Antenna Wires and Feed Lines.

  4. What you are about to read and hopefully use, is a compilation of many easy and fun ham radio and shortwave listening antenna projects that John, KL7JR, and myself have put together in this form that we believe can get you on the air and make those contacts or improve your SW listening experience.

  6. Steps to building any project. 1. Requirements: What does it need to do? 2. Design: Use or modify an existing design—most common way. 3. Gather parts. 4. Prototype: Build and test tricky parts first... Understand it! 5. Final build: Make it clean and robust, package it up. Even if you could buy it, why not enjoy making it yourself?

  7. This antenna is fed with a balance line but numerous hams preferred to feed it simply with an unbalanced coax transmission line and neglecting the degradation of the radiation pattern because it filled the purpose of portability and functionality.
