This is the third part of our series “Signal Improvement On The Road”.
If low cost is your priority in a cellular signal booster, here are a few options.
External Antenna

Extenal Antenna to Cellular Data Card
The lowest cost signal improvement option is to connect an external antenna directly to your cell phone or data card. You’ll need an external antenna adapter that fits your phone or data card’s RF port. You will get considerable improvement with this option but not as much as if you used an amplifier. A big challenge to this option is finding an adapter for your device. Many cell phones these days don’t come with a port that you can reliably attach too. Another downside is that your device is tethered to the antenna. The external antenna option runs in the $30 – $100 range depending on the antenna and cable required.
Low Cost Cell Signal Boosters

Wilson Sleek
The Sleek cellular signal booster by Wilson offers a price point under $100. It features a cellular amplifier built into a phone cradle holder. It comes with a cigarette lighter power cord and external antenna that you mount on your vehicle’s roof. The Wilson Sleek cradle has a built in inside antenna so any phone sitting in the cradle will receive a signal boost.
You can use your current car charger to charge your phone or use a Mini USB to Mini USB cable or a Mini USB to Micro USB cable.
We’ve found the Sleek to be very effective to boosting the signal of most any phone placed inside it’s cradle.
Direct Connect Power Boosters

Direct Connect Signal Booster
A direct connect type power booster requires a connection to your cell phone or mobile broadband card the same as the external antenna option above. If there is no external antenna adapter for your device, another option is a universal type direct connect like the Wilson SignalBoost Universal which uses a universal adapter that attaches to your device using velcro. Direct connect amplifier options run in the $190-$250 range.
