If you operate rtty, I operate around Field strength measurement now showed a major back loop and a decrease of forward gain almost no front to back. In this configuration, the amateur can work from anywhere over the world while being connected to its base and antenna maybe located on the other side of the Earth! This can be omitted if you use plates instead of angular bars. The Mosley takes the ice storms here, and it is not as well put together as yours. I have chose six major arguments that might determine your selection: A few minutes winding turns counter dials and both 17M and 12m were able to be matched to the transmitter.
Cushcraft MA-5B Yagi Antenna
It has been the standard to what competing rotators have tried to match since the TX-2 Tailtwister rotor was introduced. The indicator potentiometer has been improved for greater reliability. Every Mosley installation is designed using only the finest quality materials, backed by decades of antenna design and manufacturing skills. I have time constraints and have to go off and work. Leave a Reply Cancel Reply You must be logged in to post a comment. The MA5B is a design that does not sacrifice ruggedness, performance and power handling for size and ease of installation.

If someone tells you he has found the best antenna, ask him a simple question: It had nearly the same specs as the yagi I was about to build. Cushcraft A-3S Beam,Triband,3 element 10,15,20m. A lot of contests are based on specific areas of the world, so if you've got your antenna pointing that way, and its beam-width is not too narrow, you'll be as good as the next guy and won't waste beam-turning time either. The big difference is the shape, which is no more the characteristic "upside down umbrella" style. The elements are cut to size, measured, double and triple checked for correct measurement and each element is bundled and taped ready for final assembly.
WARC, Tri-band, rotatable dipole. I just upgrade to 1Kw model. I am not capable of doing simulations on this antenna , but me and 4F1BYN did some transmission test and found that the signal strengths between front and back signals is around 2 S units with an out put power of 10 watts, and negligible signals on the side lobes. All prices are in All prices are in USD. From my experiments the yagis that I constructed had wide low reflected-power bandwidths that usually cover the entire band with less than 2 percent reflected power.
