I really wanted this yagi antenna. Caveat Emptor!

Every bit of research information indicated a yagi directional antenna was the internet antenna I needed for my optimum setup. After talking to tech support at Wilson Electronics I also found out that I needed a dual band yagi so I could tune in both the upper and lower cellular bands at the same time.

(Keep in mind I am not a radio techie or mechanical engineer!) A yagi looks like your old tv antenna. They have to be aimed precisely at the source of your signal and with them more is better.

The little cross bars are called elements and the more elements the better. In the same vein, the longer the antenna the better the reception. I ran across this Cyfre 14 Element Dual Band Antenna
that promised 19db gain and I really wanted to get it! But something didn’t quite seem right…. I remembered reading somewhere that any yagi with over 13db gain was ummmmmmmm rather unusual. To further add to the suspicion, a dual band yagi gave up further performance due to the trade off between single and dual band. The best dual band yagi I had seen was 10db gain. I was hoping that the claims made by Cyfre were true so I fired off an email asking them for the performance gain per channel. They promised on their contact page that every query was answered with 48 hours. Red flag! It has been 4 days since I sent that email.

Now lets dig a little deeper. The Cyfre yagi is about 34″ long. I found a single band yagi from a reputable source that promised 15db and it was 63″ long. Remember, I said length improves performance. So if there was such an animal as a 19db yagi on these frequencies, what would it have to be??? 8 or 9 ft long? And since it is a dual band, it might even have to be longer! This was not looking good….. at all. So still digging, I found a 14 element dual band yagi from a well respected source that looked very similar to the Cyfre 14 element dual band. I checked technical specs and they were almost identical! This antenna promised a modest 10db gain per channel. Now maybe, just maybe, Cyfre is adding the gain from each band and then saying that is the antennas performance. Like the 850mhz band is 9db gain and the 1900 PCS band is 10db gain and together that equal 19db gain? So now I am really scratching my head because this really smacks of false advertising….

Later today I was reading one of the cellular forums and this one user is being very predatory and abusive toward someone wanting to purchase his product… and you know how I hate that! Guess what he was pushing? Cyfre. Well, that made up my mind. I went and ordered the Cyfre “twin” that promises 10db gain — for $20 less than the Cyfre 19db gain dual band 14 element yagi. I was comfortable with that performance.

A disclaimer…. I have been through this before where I trash on somebody’s product and realize yet again that there are too many lawyers in the world. So Cyfre, if you read this and you probably will. I will publish your email response to my query and update this post . If I can test it head to head against the “twin” I bought today, I will also post those results.   It should easily outperform my purchase 2 to 1 and if that is the case, I will eat crow and recant my false advertising assertion.  Just don’t ask me to deal with that ogre at Maximum Signal.

In the meantime, Caveat Emptor

    Since you be da guru, plus I’ll be following your link to shop Amazon, could you recommend equipment required to aid signal strength when using a Verizon UML 290 airstick. This will be a RV application. I read your frustrating thread on finding the right antenna,Yagi dual band. Now what about the cable, amplifier and router? If you like what you are currently using, list em and I’ll order em. I be thankin’ ya Andy

      Hey Boyd,

      The system I am using is still available from Wilson but they do have newer technology out there. look on the right sidebar of the blog at “Andy’s Top 10” — the 4th entry is a Wilson complete kit that should work well for you.
