Cyfre CA819

Hey guys!

Hey I bought a used Cyfre CA819 Amplifier. I have it all hooked up and the LED light turns on but how else do I know if its working right? It makes no noise etc?

Anything I can do to check it?

It will raise the signal up on the device . Only way to tell if it is working is to check signal reading on device. Do not power on the amplifier without being connected to an antenna and a device or you will fry the amplifier.

Gordon,

Would the LED light up if it was fried? Just want to make sure I didnt get a dead product.

I have it plugged in....hooked up to a cradle for my iphone and then an external antenna on my roof

I have went to using a tethered iPhone for my data this year vs last year using a data card that accepted and external antenna connection. I can't tell that the external amp/antenna makes any difference at all now with the iPhone.

Yes it would still light up . Direct connect amps work great except with iphone 4 . The antenna location on them is in bad location , it makes it difficult to get good induction connection. On iphone 3 make sure your induction adapter is on back at bottom , slightly off centre to the right. With Iphone 4 you really need to go with wireless amplifier to be effective

I am using the IPhone 4 and figured it had something to do with the unique antenna design of the phone. I may have to look into getting a wireless amp for next year. Gordon last year when I was researching the amps I read
on your site I believe that the wireless amps didn't work as good for data as the direct connect. Has the technology improved since then????

 

[Gordon Spencer]

The new Maximum Signal amps work great with data

Gordon,

I have the induction cradle, so there is not antenna to attach to the back of my Iphone 3G. Does the cradle not work with the Iphone?

I bought the new Maximum Signal wireless SCT In Car this year. It has really boosted my Sprint card and Iphone 4. I am getting a signal in areas that I usually dropped out.

 

[Gordon Spencer]

Cradle works with iphone 3 , If you read my post above I noted only the Iphone 4's are problematic due to internal antenna location
