I'd like recommendations for improving my cell service in Winter Harbor 04693 which has spotty cell coverage.
You can use external antenna like Trucker Antenna. This antenna can be mounted on truck mirrors or on a pole. It can also be bolted onto the side of a building. Adding an external antenna to your cell phone is the most cost effective way to improve reception. The price range for adding an external antenna to your cell phone ranges from $40 to over $100 depending on antenna, adapter and cable type.
Thanks for the recent responses. My solution was to install a "Wireless Extender" from Verizon. This unit is about the size of a router and is connected to my homes D-Link router via another ethernet cable. It's placed close to a window and acts like a mini cell phone tower. Our cell phones (it handles multiple phones at once) went from "searching for signal" to 4 out of 4 bars on both phones! Prices range from $200 - $250, it's not cheap but was half the price of other systems which require an outside antenna, a booster unit, and a second inside antenna. I'm very satisfied.
Adding an external antenna to a phone is no longer an option . The phone manufacturers have stopped putting RF ports on the phones so end users can no longer do this. - - - Updated - - - A Femtocell ( Wireless extender ) is only a solution for folks that have a high speed wired internet connection . Also keep in mind that they only generate signal for the carrier they are issued by . If you have other users in household on other carriers , they are out of luck.
