I have seen some references to the antenna circuitry being tuned between the 180 and the 270. (mostly from that "leaked" FCC application)

Has anyone noticed the 270 having better signal strength than the 180?

I love my 180, but my office moved a block away, and I landed in a pretty bad coverage hole. The phone MOSTLY stays connected enough to ring, but when it rings I have to grab the phone and run and stick my head out the window to talk.

Obviously this can't go on for long. Any chance that upgrading my 180 to a 270 would be enough to make the difference?

Alternatively, is there any antenna upgrades I can do to my 180? (not the sticker type...)

Wishful thinking? ;>
