We have the Weboost RV setup. in areas where the signal level w/o the booster is in the -100 to -110db range a omni outside antenna and being within a few feet of the internal antenna.
When the singnal level is in the -110 db or lower, the phone needs to be in the cradle antenna and the outside antenna sometimes needs to be a yagi.
And in any case, the amount of boost you get depends on how close you are to the inside antenna. If all you need is voice phone service or messaging, the lower your signal can be. If you want internet you want as strong a signal as possible which is best achieved by the phone being in the inside antenna cradle.
As an example this last weekend I was in a place with a unboosted signal level of -110db, voice but very marginal internet. with the weboost on and the internal antenna about 4 ft away the signal was near -100db, not bad, very good for voice marginal for internet. With the phone in the cradle signal level was -80db, very very good for internet.
I've been studying the WeBoost 4G-x RV, thinking about upgrading from my Wilson Sleek. When you mention about putting the phone in the cradle in your Weboost system, I'm left confused, as in studying online what is included with the Weboost 4G-x RV package, I don't see a cradle. Is the 4G-x RV the model you have, or do you have a different model?
I have the 75ohm RV system, but it didn't come with a cradle antenna, I bought it seperate. What I can say is that the cradle can gives me 10db or more boost over setting the phone next to the antenna included with the RV system. How much difference in boost is dependent on how strong the unboosted signal is. The booster won't always give the 50+db max gain. Typically the system will boost to a signal level that gives a certain Signal to noise ratio and then the provider limits power. They only want to allow enough power to give the acceptable performance level. increasing signal beyond that gives no benefit to you and can have a negative effect on others on the same tower.
What I've found is that when the unboosted signal is around -115db or lower (below about -115 is a no signal condition) the cradle gives better reception. I've had conditons with no signal w/o the booster and with the booster -100db so it's really maxing out the gain to even get me a signal. In that case the cradle gives me something useable, the inside antenna marginal if I'm next to it and nothing if I'm even a few ft away.
