    11 meter dipole help???

    I have found an answer to my question about the swr changing at altitude. "A dipole antennas impedance increases as its distance from the ground increases." Thus, it decreases the antennas impedance as you lower it back down. I trimmed the antenna setting the swr close to the ground (7-8') for...

    11 meter dipole help???

    Update, OK I used a new so 239 connector, cut to length first then soldered connections, and I just used a piece of hard flat plastic and not over-complicated PVC tubing this time. I have 1.5 swr across the band at altitude; I think I will let it be. No balun no choke for now and I did away with...
