But in principle, yes.
-Mole - dattaway, on 10/12/2007, -0/+5I've used the biquad design from seattlewireless.net for wifi and it turned a hundred feet into many miles in the country. Very easy antenna to build and seems better than the more complex yagi. The antenna is everything.
- Crass22, on 10/12/2007, -0/+5very clever hack indeed
- dhughes, on 10/12/2007, -0/+3 The best part was the comment from "Adrian", way to go psycho over nothing.
- BIGmog, on 10/12/2007, -0/+3Neat but would it work for US based cell phones?
- atmicrat, on 10/12/2007, -0/+3I would like to know how he connected the thing to his phone?
- inactive, on 10/12/2007, -0/+1If a phone rings in the middle of a dead spot does it make a sound?
- kevin_ou, on 10/12/2007, -0/+1FYI, New Par towers belong to Verizon.
- JayRod, on 10/12/2007, -0/+1And here I was thinking it was just this all along.

http://en.wikipedia.org/wiki/Universal_Mobile_Telecommunications_System - dougmc, on 10/12/2007, -0/+0Ham radio operators (and I guess other guys who understand antennas) have been doing this sort of thing for a while now ...
Build a Yagi antenna for the band that your phone operates on. Mount it outside, pointing at your closest tower.
Build a dipole antenna inside for your band, perhaps two or three of them in different orientation so the signal inside won't be directional. (But a single dipole might be good enough.)
Connect the two antennas via some good coax (It has to be good, because 2 GHz signals are strongly attenuated by cheap coax. Of course, if you can keep the length of the coax short, it won't matter so much.)
Presto ... signal where there was none!
Actually, you might not even need a Yagi antenna outside -- a dipole will do the job too, but if you're a distance from the tower, you might need that Yagi or another form of high gain antenna.
(And yes, this is basically what this guy did.) - BigRedBall, on 10/12/2007, -0/+0The phone rests in a car ‘cradle’ - a Nokia CR-47. This is the only way to hook up an external antenna to an E61. The CR-47 comes with an antenna fly-lead with an FME connector on the end - to which my ersatz antenna is attached.
- BigRedBall, on 10/12/2007, -0/+0Hi S1mba:
Perhaps you can enlighten me - I don't understand your comment: how could the antenna damage the phone if I adapted the dimensions for 2.1Ghz? - Desertsnowman, on 10/12/2007, -1/+0Going to try build one ASAP!
- S1mba, on 10/12/2007, -2/+1"However, in an incredibly geeky flash of inspiration, I realised that there really isn%u2019t much difference in operating frequency between WiFi (around 2.4Ghz) and UMTS (2.1Ghz)."
But not quite geeky enough, since you failed to realize that there is enough difference that your SWR (standing wave ratio) is probably unacceptably high, and you risk damaging the final amplifier stage in your phone when transmitting. - avaloncourt, on 10/12/2007, -2/+0DCMarkie: That link is really awful. It's supposed to be showing cell towers but it's showing any tower regardless of use. I ran my area and it's showing radio station towers, paging towers, a cable company off-air antenna reception tower, and private company radio towers. None of these have anything to do with cellular.
- inactive, on 10/12/2007, -2/+0you want reception!
why did you not come to the GREAT Raid517
raid517 please share your infinite wisdom with us
add a couple of insults if you please ... - bzaks, on 10/12/2007, -8/+3Don't buy a cell phone.That'll give you a FREE service plan.
- inactive, on 10/12/2007, -24/+15/me watches rick1dude@yahoo.com get spammed
- piratebill, on 10/12/2007, -22/+5n00b
- rick1dude, on 10/12/2007, -64/+2Please how do i hack my network provider so i can make calls free of charge or at very low cost, pls mail me : rick1dude@yahoo.com
