C-3SS
Unsurpassed Performance in a Small Package
Knowing there are installations that require the absolute smallest footprint, Force 12 answers the need with the C-3SS. The C-3SS uses proven overlay design techniques developed by Force 12 for the most efficient multi-band Yagi possible. There are minimal parts and no traps, making the C-3SS a true multi-monoband Yagi.
The C-3SS is the same, basic design as the famous C-3S used by more and more amateurs for outstanding performance and used by DXpeditions the world over. To achieve a smaller size, the 20 meter elements on the C-3SS are shortened using pre-formed solid rod in the most efficient linear loading technique. The rotating radius is only 13.5'! We receive comments every week on the sparkling performance of the C-3SS.
The shorter 20 meter elements provide essentially the same gain as the full size elements, cover the whole band and actually has a slightly better F/B. The performance on 15 and 10 is the same as the C-3S, as the elements are full size. The C-3SS comes standardly rated for 100 mph. As a bonus, the C-3SS also has gain on 17 and 12 meters (use your rig's tuner to match it) for full 5 band coverage.
The C-3SS comes in a 4' long box (8" x 10") and the finished product weighs only 27 pounds. Fast, simple assembly. Please look through the brochure on-line at the main menu for how the C-3SS is constructed and packaged. The antenna can be painted for concerned neighbors and a roof tripod or Force 12 Low Profile tower is an excellent installation method. The small size hides the high performance.
The C-3SS is your answer to the highest quality and highest performance in a small package.
