a non metal roof/walls etc. are transparent to the frequencies in question. so you need about 15 ft seperation between inside and outside antenna to avoid feedback. Even an airstream with windows isn't going to provide much isolation. And most objects outside don't block much signal. Thats why a cell phone works in your house.

High water content does block the signal, but few objects have enough water content.


Ok thanks. My manual calls for 25' separation but I experimented and have the 2 antennas about 15-18' apart. I'm getting all green lights on the booster and my signal reading goes from -93 to -63 when placing the phone right next to the inside antenna. So it's working fine.

How does this answer the OP's question?


External amps and antennas are not a fix for everything, especially if there is no tower close enough to you for the service vendor you subscribe to.

No tower signal in to the amp = no service

Reliable service requires several cell towers within 5 or so miles of you.

If you have one bar of signal on your phone direct, then external amp and antenna "might" help, but it might not.

Nothing magical about it.

Not to mention Verizon and ATT use two different incompatible methods with pros and cons between the two systems.

We have a campsite way way up north where we work from in the summer. Installed a 40' antenna (extending pole with guy wires) and a highly directional antenna, coupled with a SureCall booster and the indoor antenna. Omnidirectional and Yagi didn't work well for us, this antenna (Link) has to be pointed very precisely, but delivers up to 15 db gain (in addition to the booster), which is exceptional. We started with 1 bar signal and now get full bars and roughly 20 Mbps internet speed, which is fine for remote work.

Thanks
I'm familiar with bit error rate on cell tech. I will get the weboost omni. Past experience screwing around with yagi ornotger more directional antennae are more work than I need. Usually if there's no signal at all, I'm in some sort of hole or there's a mountain blocking the last known tower. I'll likely move on.

Biggest headache I run into is the site has 1 bar intermittent. Someone uses more data, I get knocked off. If I put in flight mode, I can reaffilliate. For how long? Who knows. I'm guessing from some antennae I see at some of these sites someone is hogging what little signal there is. Booster will give me a fighting chance as well.my questions are now best install techniques.

Thanks

I've found that with the outside antenna up high (15') fifteen feet of horizontal seperation is adequate as well.

I often go from -120db down to -70db. And there are places we go that w/o the booster the phone has no connection but with the booster I can get a signal in the -100db range, adequate for most use. If the booster can establish communication with the cell tower your usually good to go.
