I have been doing some research on building a magnetic loop antenna. I built my first antenna (a half wave inverted v dipole), I am hooked and looking for another antenna project. My concerns are mainly coupling and tuning. As far as coupling is concerned I was thinking of using a gamma match system vs the common faraday loop, from what I have gathered, the gamma match system produces more consistent results. I intend on using an air variable capacitor for the tuning cap. My questions are these. 1. Is the gamma match tuned for desired impedance? My goal is 50 ohms. 2. If the gamma match is used for achieving desired impedance, the tuning cap is used to achieve desired swr or resonance? I have read pages and pages of material and I am still trying to wrap my mind around the tuning process using a gamma match system in conjunction with the variable cap. Any advice would be much appreciated. Thanks -Alex
