Hi, and thank you in advance for taking a look at this post. I've come a long way since my first post, but still learning a ton. I'm not great with antenna theory, and haven't been able to locate information about my question. Scenario: a friend and I each have a 40m Pixie radio set for 7.023 - 7.026mhz. We are both General class, and want to work in the 7.026 frequency to practice our CW code. We will be on a university campus, and sometimes in the same building. We should like an extra short antenna for these. I know there are shorty stub antennas manufactured for other bands. But I don't fully understand the theory behind it. Essentially we would want to build a short antenna that is resonant at 7.026 and only that frequency. I am assuming that since we don't need to cover and entire band, this would make this possible. Anyone have information, websites, or plans to make this happen? We have access to a wireless engineering lab on campus, and will be able to fully test the antennas before using them. Thanks! |
