Also, I would tend to say that the ONLY clamp that really has any tension on it at all is the very first one. By the time you get to the third clamp, there's no noticeable tension on it. 73, Jon NA9D

MFJ exists and continues to do well because they have a number of unique products no one else has. They offer a decent value for the price as well. The quality is just OK. It is good enough for ham u

While an LPDA is a great antenna (I worked for Dr. Paul Mayes who was one of the inventors of the beast), I do question it's usefulness in the amateur world at HF. An LPDA has less gain than a Yagi a

I could believe they have better F/B than a small Yagi. I also believe that a good sized LPDA would outperform a small beam. However, I am not completely sold on the idea of absolutely better perform

The SteppIR antenna has been discussed here ad nauseum. My main issues with the SteppIR: 1.) Mechanical. How reliable is it? What about condensation inside the motor, etc. and then what about when al

Log-Yagi's are great designs. You have more active elements and more parasitic elements to give you increased gain as well. The log-yagi though is still a relatively narrowband design compared to a s

I'm really curious about those numbers. A Cubical quad theoretically should be no different than a Yagi. The Force 12 web page has a good discussion on that. As for what the numbers mean, who knows?

I totally question the veracity of anyone that claims a cubical quad with the exact same dimensions as a yagi has more gain. It's just not true. Force 12 dispels this myth on their website. 73, Jon N

2 2 NOT 4. There is the same number of elements. It's just a different type of element. In a quad your driven element is a loop and so are your parasitics. In a yagi, it's a dipole. Both are equivale

I'll agree. I did some research myself and found this to be true. If the loops are are talking about are full wave as compared to half wave Yagis, then yes, you'll get more gain. The question is if y
