We ran two AGS at the same time to test the difference between a weatherised V-dipole and a static mounted Turnstile on the top of the roof. The pass was around 68 degrees in maximum elevation- so not ideal, but good enough for a comparison. Steve reclined on the roof and used a spare curtain rod to hold the V-dipole in a static position for eleven minutes. We ran a spare radio cable from the V-dipole through the garage door to AGS 12, while AGS 3 stayed connected to the turnstile. Comparing the images is interesting: AGS 12 / V-dipole picked up the satellite signal a little earlier, but more bands of interference run through the start of the image. In contrast, AGS 3 / Turnstile pick up the signal later, but the middle part of the image is generally clearer. The antennas lose the signal at about the same time to the South.
