... Randy: I noticed nobody answered question 1. When the original Ringo was introduced, performance reports were all over the map. Some worked fantastically well, others fantastically poorly. It was finally discovered the difference was due to mast and feedline radiation. Sometimes the lengths were right to radiate well, other times, the antenna radiation was canceled by unwanted from the support and feed. So, the radial kit was added. Four radials just over a quarter wave (20 inches seems to work well), but I don't recall the exact position on the antenna. Just below the feedpoint seems right, but I defer to CushCraft if you can get the location from the Ranger II manual. -- Crazy George CG & Randy - Correct about the Ringo and original Ringo Ranger performance reports -- some lamented that it was the best dummy load Cushcraft ever built ! I liked mine, and actually used a Ringo Ranger at 200 feet hung upside down (for proper radiation pattern) for a repeater's transmitting antenna in 1976 - with great results. We replaced it 2 years later -- with a heavy duty commercial unit (that could take the wind abuse). The Ranger II has a coax of specific length between the radial ring and Ranger -- so that the distance of the radials is correct. This is covered in the Ranger II manual. http://www.cushcraft.com/support/pdf/951290.pdf So, you have a standard Ringo Ranger and you can purchase the parts from Cushcraft - IF you desire to upgrade it to the Ranger II model !!
