Hello friends, This is my first post to the list. My questions are based on a Force 12 C3S constructed to the 80 MPH diagram in this manual: http://bit.ly/F12-C3S I purchased a new C3S from he Colora
Interesting we have the same first and last name. It is sad that Force12 could not ship you all of the pieces for this antenna, this is not an inexpensive product. I have an older C3S that I purchase
While Force 12 antennas have always been well designed and, for the most part, well built, the Force 12 BRAND has suffered from poor business management. The company/brand has been sold several times
John N4EEB, I also have a C3S. It has been up quite a while, got it back when N6BT was still at the helm with Force 12 (& it was easy to contact him with questions I had perfect SWR on 15 and 20 bu
Of course. But the tricky part is being able to rig the antenna so that SWR can be measured at sufficient height to remove ground influence on the tuning AND the so that it can easily lower it for ad
Hi Jim, What I did was note the resonant frequency at 70 feet before finishing securing to the mast then lowering it down and sat it on saw horses. Took note of the new resonant freq on the saw hors

Bob, I have had two of the C3Es over the last 20 years. I found that using the measurements in the instructions worked out just fine with the exception of 15 because I have it stacked with a 40 meter
Here's what I did to investigate John's scenario. First step was to create a model of the C-3S using variables to control the wire coordinates. The AutoEZ "Create Stepped Diameters" dialog makes shor
Nice job Dan! Is the C3S design really that far off? It would make seem to make sense to adjust both the reflector and driven element. John KK9A Here's what I did to investigate John's scenario. Firs
How do, John is having "fun" tuning his Force 12 C3 on 10 meters. I'm sure I'll get corrected if my aging brain is incorrect, but I seem to remember that you can get real close, adjusting a HF yagi a

First, thank you so much for the extreme response from hams both on and off the mailing list. I'm truly grateful for everyone's input. I have learned so much already. 1. Two element yagi antennas of
