I would like to build my own, I just need to figure out where to get
the parts from. Again I did not see any thing on that site so far.
The one I bought so far does not seem to make too big a dif so far.
And all the cust service responses from various cell phone antenna
sites say there is not much for 900,1000, 1100 mhz which is what the
specs say on the phone. And yes I am a layman for this but willing to
learn what I can if only for the knowledge.

That`s reasonable. Cell phones communicate with whichever base station
works best in a wide network. This is almost the ultimate space and
frequency diversity system. Antennas are low which limits range. No
problem as contact is lost it is immediately re-established
automatically with another station, the new best choice.

As azimuths between phones and bases are constantly changing,
concentrating phone energy at a articular azimuth does not make sense if
the phone is moving.

Efficiency makes sense. Concentrating energy along the horizontal makes
sense for most users.

The having no port is the main problem...That means you
have to use those coupler devices that fit behind the antenna
in the phone...Unfortunately, I just had to buy a new phone,
and my new one is the same way. No port...They make a sleeve
that fits over the top, and has a patch to couple to the internal
antenna, but I have to wonder how well it works...Some reports
seem lackluster...As far as antennas, I guess it depends on
what you want...A connection to a cheap UHF TV antenna
might work ok....But most long distance house cell antennas
are yagi's that I see sold. Anything commonly used for UHF,
could be adapted to cell phone...Often on those freq's, just
moving a few feet can make a big difference...So I'd try different
locations, and try to find "hot spots"...Thats about where I would
mount the antenna if it's not going to be real high...
I'd like to find the goofball that decided these phones don't
need an antenna port.... Whatta putz....Having an outside
antenna makes a huge difference out on the interstates... MK

That url above does not have the item you ordered. Did you mean to
paste this one:

The above one has Motorola C650 antenna that does not require a port on
the phone. It attaches to the back of the phone with velcro attachment.
That should solve your no-port problem and give better reception up
yonder.

If You can drill a hole in Your motorola's plastic enclosure
(it's probably removable so You can have one for replacement)
probably there will be 50OHm port inside.
When they test phones - all have to be connected with measuring
equipment - directly feed through 50Ohm cable /there are some
situations that producer prepares "test fixture" which looks just
like small patch antenna mounted on the phone/. Anyway - even on
nokia 3650 (this model has internal tri-band patch antenna)- when You
remove front panel - there is a connector - to simplify test setups.
