Default GSM Reception Questions

I am looking for input into Mobile 1900Mhz Antennas for Vehicle Use.
Has anyone had positive experience with a certain brand or model that you
would share??? Please...

Would anyone have experience with Repeater/Amplifiers for the 1900Mhz

Range.
I am looking to install an In-Building Repeater and would like any input
available.

Thank you in advance..


You may want to talk to your carrier before you try to install an in
building repeater. You cannot on your own just start transmitting on the PCS
frequencies, as they are protected by the FCC for the carrier that paid to
use those frequencies. And by transmitting on the frequencies used by the
carrier of those frequencies you may cause interference problems.

Unless you're a business, I doubt it would do much good to talk to the
carrier. I also doubt that there is any real problem as long as you get an
FCC approved unit, and install and operate it in the specified manner.

You can't install a BDA to intentually amplify someone elses signals,
its a violation of FCC rules (assuming your in the US).

If your not in the US, then I have tons of experience in BDA design and
deployment, having designed a few jail and courthouse systems. They are
very expensive and unless your prepared to spend 3 dollars per foot on
slotted cable, approximately $5,000 on a high quality amp, and core
boring holes on each floor to make the vertical run....don't waste your
time.

Those are licensed frequencies, so legally you cannot on your own just go
out and put a repeater in, you would have to get a license from the FCC. And
again that is only legally.

There is NO license that he can get from the FCC to amplify someone
else's signal with a BDA, it doesn't exist....sorry.

I know that, and you know that, but I do not think the original poster knew
that. He must think they are like the wi-fi frequencies.

Both Andrew Corporation (EAC-50 Repeater Kit, Model ASPM1850-50,
http://www.antenna.com/repeaters/eac50_pcs.html, 440-349-8647) and
CellAntenna Corporation (CAE50 SOHO Repeater Package,
http://www.cellantenna.com/repeater/CAE50new.htm, 877-998-2628) assured me
that their bidirectional amps are FCC Approved, and that no FCC license is
needed to install and operate them here in the USA.

* Wilson Electronics (BD800AM-B / BD800AM-B50,

have all assured me that their bidirectional amps are FCC Approved/Type
Accepted, and that no FCC license is needed to install and operate them here
in the USA.

A typical home in the USA is quite different from a typical jail or
courthouse. The systems above are "only" about $500-700, but reportedly do a
good job of providing coverage in a limited area (500-1000 sq ft or so).

A house installation will not give you the required 40 to 60dB isolation
required for a BDA (you need a minimum double of what the gain of the
amp is). The amplifier will self oscillate if the isolation is not
there and will end up with more problems than you started with.
