External Antenna and Cellular SIgnal Boosters Links Tutorial

I have done some research over the years with help from many of you on
these forums. I've found a Antennex 9db, 6 element Yagi antenna + Times
Micro LMR-195 cable, works for my portable outdoor camping signal
boosting needs.
I have not used a signal booster, but others have claimed good results.
The cost is fairly expensive, but not being tethered to the cable
leading to an external antenna must be very attractive, to those who's
only phone connection is a cellular phone, like at a remote home/cabin,
requiring it to be connected to an external antenna 24/7, in order to
make and receive any calls. The home doesn't even need to be a remote
cabin, just one that gets a poor quality Verizon signal, which an
external antenna would overcome.
I have some links that have been helpful in not only getting some good
advice and products, but in understanding antenna basics enough to
begin asking the right kind of questions about the kind of equipment
needed and proper set up.

Since I have never used a booster, or found it necessary, I'd like to
find out what booster equipment owners are using and how much it cos to
set up.
How well does it work and are there any call quality glitches?
How far from the internal repeater antenna does one need to be? Looking
for any cell phone booster users to see what brand they have the set up
and how it works.

I'm still looking for anyone who is using a panel a 7db antenna as
shown on Critrerionwireless site. I'd like to use one for
portable/backpack use. It's small enough to carry easily and then use
the phone's debug menu to aim for best signal. Apparently, they do not
need to be aimed as closely as a Yagi. The panels don't have quite the
amplifying capability as a Yagi, but they don't need a ground plane and
also work on 1900mhz/PCS frequencies. Also would appears they would
have more gain than an omnimount 3db . A small panel that needs no
groundplane and the ability to aim for better reception sounds ideal
for my usage. Just want some users report before buying one.

A few important points. The phone needs to have a hard wire external
antenna adapter connection port to get the best signal from an external
antenna. Use quality connecting cable to the antenna and phone elements
to reduce signal loss over the cable. Thicker cable is better
especially for long runs.
Most important! Follow specific grounding wire set up and codes for
external antenna/mast structures, to avoid electrocution from
lightening or a downed power line, making an unexpected connection with
your antenna system.

I've had the Cellantenna.com DA4000 for years. It turns your little
toyphone milliwatt transmitter into a bagphone transmitter ONLY when you
are out in the fringe. On CDMA, instructions from the tower tell the phone
to turn down its power until the tower sees all the users fairly level on
that channel, the only way a shared channel receiver can switch this fast
without being swamped. So, what the amp gives you on CDMA is simply a 20
db or so higher CEILING of output power. It will also cause the cell you
are closer to to turn down the power an extra 20 db to compensate for the
amp's output....plus any db the antenna system gain is adding. Batteries
last very long transmitting through the amp, unless you are in fringe.

Of course, on AMPS, the non-functional 150-200mw phone now has a bagphone
transmitter running 3W into a decent antenna in a better location than
heating up your brains. The toyphone now has bagphone range, like a real
cellphone used to.

Of course, the company isn't too please as when you're in between cells,
running more than signal generator-size power, you are heard in way too
many cells reducing revenue/sq mi....They view this as a bad thing....(c;

It'll make a toyphone work in the Francis Marion National Forest where it
had no chance of any connections on any company cell, before....especially
if I hook it to the 11 element Decibel Products paging beam at 30'...(c;

Hey Larry!

So the Dynamic Power Control of the CDMA system keeps the total
amplified signal from going over the CDMA spec.
So the CDMA signal going through the booster isn't allowed to boost the
CDMA signal strength beyond what the phone could put out without it
hooked up?
Or simply, the booster does nothing at all to boost CDMA signal?
Under any circumstances does the booster help with CDMA reception?

At least it's a good emergency 3 watt amps booster! I suppose when
brodcasting at higher than rated power levels, one needs to be
responsible for the overall network and other callers needs as well.

That's funny, I get a picture of you lugging around a 12 volt car
battery to power the booster and then noticing the little cell phone
battery lasts much longer

thanks for all the tips,
David

Wow! Larry DOES understand! Who knew?
