Comon, now - The image is crappy but that velcro antenna may be a good
idea for those phones that do not have an external antenna port.
Enlighten me about why you think it is junk. I mean, I would really
like to know if you care to elaborate just a tad bit more to support
your argument. Thanks.

Well, if you have worked with antennas at all, you would know why...

.... but then, even sugar pills (placebos) cure illnesses... and in that
sense--could just work!

I mean, I go to extremes to attempt to keep an open mind... that cell
antenna even closes my mind... frown

Warmest regards,
John

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.

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.

Yea, I've seen that. They also make a "sleeve" version
which is a perfect match for my nokia phone. I just wonder
how well they actually work...Actually, I would prefer to make
one myself, but I'm not sure how I would want to go about it..
IE: would I need a resonant 800 mhz "coupling antenna", etc..
I tried just making a experimental patch out of foil, and sticking
it on the back, behind the internal antenna, but it didn't seem to
work.. Anyone have any good ideas how to homebrew one?
Actually, I've also been considering just drilling a hole in the phone,

and installing a antenna port....

Send me $29.99 and I'll send you the plans and a roll of aluminum foil with
some copper tape... grin

Dave:

Interesting design, can't wait to show this to the 2.4 Ghz guys here...
simple, eloquent and even looks like it will work!!!

Warmest regards,

How big should this cardboard be? I might try this. I bought some
cheap tv antenna rabbit ears and got a minimum signal to check
messsages in my basement. What actually is the antenna inside my cell
phone anyway? I just need a larger version of that maybe?

Here's a cut-out template parabolic reflector. Works for all frequencies.
Uses cardboard and aluminum foil (from the kitchen):

Check the Nokia Web site, most, but not all, phones have an antenna
coupler option available.
